1. the physicochemical property of low-carbon alcohols
Industrial low-carbon alcohols (C≤4) are colourless, transparent, volatile, incendive liquid at normal temperatures.64.8 DEG C of boiling point, phase
To density (20 DEG C) 0.7914.Industrial low-carbon alcohols chemical property is more active, and the chemical reactions such as oxidation, esterification, carbonylation can occur,
Low-carbon alcohols do not have acidity, and molecular composition has the hydroxyl of basic character, but is not also in alkalinity, in being in phenolphthalein and reindeer moss
Property.Low-carbon alcohols are compared with gasoline, with calorific value is low, the latent heat of vaporization is big, anti-knock properties are good, high oxygen content.Low-carbon alcohols slightly alcohol smell,
It is toxic, it can cause to have a stomachache into human body, the symptoms such as muscle cramp, dizziness, weak can cause blindness even dead when serious.
Low-carbon alcohols have following characteristics as fuel:
(1) due in low-carbon alkanol molecule containing aerobic, by mass, low-carbon alcohols oxygen content 30%~have 50% it
Between, thus the air capacity needed for low-carbon alcohols completely burned, than gasoline much less, the tail gas for generation of burning takes away the heat of loss
It correspondingly reduces, is thus improved engine overall thermal efficiency, caused pollution level is lighter than gasoline after burning.
(2) low-carbons alcohols calorific value is relatively low, and low-carbon alcohols quality low heat value only has the 45.5% of gasoline, therefore, same
Under the thermal efficiency, the effective mass fuel consumption rate of low-carbon alcohols cleaning new energy is high；Low-carbon alcohols cleaning new energy is oxidizing combustible, it
Excess air coefficient required when completely burned is much smaller than required value when fuel oil gasoline in cylinder.
(3) latent heat of vaporization of low-carbon alcohols is 3 times of gasoline or so, and the high latent heat of vaporization and low vapour pressure will cause to mix
Gas formation and starting difficulty are closed, but intake air temperature can be made to further decrease, improves volumetric efficiency；Simultaneously because low-carbon alcohols are clear
The latent heat of vaporization of clean new energy is big, can improve the cooling condition of engine interior after burning, improve the dynamic property of engine, drops
Low exhaust temperature.
(4) low-carbons alcohols material itself has higher octane number, has higher knock resistance, is improved to passing through
Engine compression ratio is highly advantageous come the thermal efficiency for improving engine, therefore is good gasoline engine substitute fuel, and improves vapour
The excellent additive of oily octane number；Regular gasoline is mixed with 15%~20% low-carbon alcohol ate, and octane number can reach high-quality vapour
The level (97% or more) of oil.
(5) boundary of catching fire of low-carbon alcohols cleaning new energy is wider than gasoline, can burn under diluter mixing gaseity,
This will allow engine steady running under the conditions of lean mixture, highly beneficial to exhaust gas purification and reduction oil consumption.
(6) burning point of low-carbon alcohols is higher than gasoline, is susceptible to fire incident, more safe to use than gasoline；Low-carbon alcohols clean
The boiling point and vapour pressure of new energy fuel are all lower than gasoline, contribute to the formation of petrol-air mixture, but wherein lack high
Volatile ingredient, it is unfavorable to starting.So the cold start-up agent for adding independent research in the product is adjusted, to overcome this
Disadvantage.It is added to compounding cold start-up agent in fresh fuel and solves the problems, such as cold start at -10 DEG C or more, in In Shanxi Area
(Xi'an, Weinan, Hancheng, Tongchuan periphery) works well through real steering vectors.
(7) low-carbon alcohols have swelling action to certain nonmetallic materials (such as plastics, rubber), (such as to certain metal materials
Sn, Pb, Al etc.) there is slight corrosiveness, it should take appropriate measures, independently be ground so adding in the product in use
The anti-swell rubber agent of hair, to overcome this disadvantage.
As a kind of good solvent, low-carbon alcohols cleaning new energy has the rubber-plastic sealing part in automobile oil supply system and oil pump
Certain swelling action will increase rubber-plastics material aggressivity.
Swelling mechanism：
Fresh fuel has swelling action to the non-metallic component of the materials such as partial rubber in fuel system, to influence these
The performance of component.This is because 1) rubber is made of net macromolecular, and when rubber is immersed in fresh fuel, low-carbon alcohols
The organic molecules such as class can penetrate into rubber network molecule so that reticular structure expands, and infiltration reaches balance and limited expansion occurs；
2) the similar principle that mixes.Polar rubber is easy to be swollen in low-carbon alcohols, the property and low-carbon alcohols of degree of swelling and rubber
Content it is related.Anti- swelling action of the rubber in fresh fuel is not that low-carbon alcohols add with the simple of the anti-swelling action of fat hydrocarbon
With, but the compound action of the two.
Anti- swelling method：
Low-carbon alcohols does not have swelling action, aromatisation gasoline larger to oil resistant rubber swelling action oil resistant rubber, ether with
The mixture cosolvent of ester is very big to oil resistant rubber swelling action.Therefore, suitable fat hydrocarbon, anti-swelling are selected in fresh fuel
Agent helps to reduce the swellability of oil resistant rubber.In fresh fuel, using cyclic annular phenols, methyl tertiary butyl ether(MTBE), fatty amine as new
The anti-sweller of fuel, their structure are made of the non-polar group of oleophylic and the polar group of close hydroxyl, are had very strong
Surface-active, very strong suction-operated is generated to solid rubber surface energy, forms one layer of firm protective film.When absorption, sulphur
The polar end of acid is adsorbed in rubber surface, and non-polar end is outside, is linked with dye base, in this way it is prevented that plasticising in rubber
Agent is extracted and proposed by fuel, to achieve the purpose that anti-swelling.Through real steering vectors, work well.
Low-carbon Aalcohols fuel contains hydroxyl, can be miscible with water, and HC fuel hydrophobicity is strong, thus low-carbon alcohols and hydro carbons
Intermiscibility it is poor, when low-carbon alcohols and gasoline are mixed in a certain ratio, there is lamination in certain temperature range.So
The dispersant that independent research is added in product, to overcome this disadvantage.
Liquid, which dissolves each other, follows the principle of " similar to mix ", i.e., power between power and solute and solute molecule between solvent and solvent molecule
Approximately equal, then molecule similar in the good polarity sizes of two intermiscibilities, the close of molecular separating force is so the strong low-carbon alcohols energy of polarity
It is dissolved in the strong solvent of polarity (such as water), is insoluble in nonpolar solvent (such as gasoline, hydro carbons), and gasoline can only also be dissolved in non-pole
Property solvent in improve the stability of low-carbon alcohols cleaning new energy, it is necessary to find one kind can interact with low-carbon alcohols again with
The similar cosolvent of Hydrocarbon Property is current, and the cosolvent used in domestic low-carbon alcohols cleaning new energy has ethers, higher alcohol and fat
Hydrocarbon, low-carbon fusel, aromatic compound etc., for example, the .MTBE such as MTBE, isobutanol, tert-butyl alcohol addition improve low-carbon alcohols with
The intersolubility of gasoline, but its solubilization-aid effect is not so good as the alcohols such as isobutanol, this is because MTBE molecular polarities are small compared with alcohols, tertiary butyl
Presence hydrogen bond formed to oxygen atom and water, low-carbon alcohols again have certain inhibition, and the hydrophilic group-OH in isobutanol can be with
- OH in water and low-carbon alcohols effectively connects with hydrogen bond but isobutanol is expensive, and supply lacks so finding cheap
Novel cosolvent be the main problem that should solve in the application of low-carbon alcohols cleaning new energy
Low-carbon alcohols-Hydrocarbon System chance water resisting phase separation performance is poor, to make low-carbon alcohols-water-hydro carbons mutual at normal temperatures
It is molten, it is necessary to find one kind can with water or low-carbon alcohols interaction again cosolvent similar with hydrocarbons property, to improve
The water capacity of fresh fuel.Additive water capacity is big, and stationary phase is long.Compared with low-carbon alcohols cleaning new energy, the general tradition that is added helps
The low-carbon alcohols cleaning new energy of molten stabilizer, the moisture for dissolving in 0.1%~0.5% at normal temperatures just generates phase separation, and this product
Water repellent agent can generally dissolve in 5%~7% water, it is not in phase separation that highest, which can dissolve in 13%~15% water also,.
(9) method that low-carbon alcohols cleaning new energy anticorrosive additive uses passivation of metal surfaces, makes the inhibition of metal imitate
Fruit significantly improves, this is because the structure of component contains biradical group, the nonpolar alkyl of existing oleophylic in formula, and has close alcohol
Polar hydroxyl groups, alkyl can form firm coated oil with metal surface strong effect, and hydroxyl can be cleaned with low-carbon alcohols it is new
Energy matrix, which dissolves each other, to be connected, and to which the contact of metal surface and low-carbon alcohols cleaning new energy matrix be isolated, avoids low-carbon
Alcohol cleaning new energy becomes metal deactivation method to corrosion of metal, this method for making metal surface generate one layer of oil film, it is
Low-carbon alcohols cleaning new energy self-assembling formation in flow process, and the passivation of metal surface is realized at normal temperatures, generate one layer
Fine and close metal protective film, to effectively prevent the corrosion of ion.
Additive turns to overall effect, general metal inhibitor imitates red copper to the slow release of metal by single effect
Fruit is good, but poor to No. 45 copper and gasification equipment material anti-corrosion effect.Additive is to copper, aluminium, No. 45 copper, zinc, gasifier material
Equal various metals all have preferable anti-corrosion ability, and especially good with fuels mutual soluble.
Additive has the oil quality of fuel certain facilitation, because having selected to be conducive to improve low-carbon alcohols in component
The active ingredient of cleaning new energy oil quality, such as fatty alcohol, surfactant, antirust agent all contain biradical group, Ji Nengrong
It can be dissolved in dye base again in gasoline, there is the stablizing effect for further promoting hydrotropy.Meanwhile strong acid-base is not contained in formula,
The acid-base balance of oil product will not be destroyed.
Low-carbon alcohols cleaning new energy is gas barrier
Since low-carbon alcohols cleaning new energy is in the case of incomplete combustion, hydrocarbons cracking, oxidation polymerization generates carbon
Slag precipitates, and makes vaporizing chamber nozzle blockage, and vapour lock occurs.
Fresh fuel adds anti-vapour lock agent, and low-carbon alcohols cleaning is added in the substances such as ketone, aldehydes, ethers that additive uses
In new energy, hydrogen bond can be formed with the principal component of low-carbon alcohols cleaning new energy, low-carbon alcohols cleaning new energy boiling range can be improved, made
Boiling range temperature when 50% and 90% obtains suitable for adjustment, to change the vapour pressure of low-carbon alcohols cleaning new energy, effectively solves
High temperature vapour lock problem.
(11) stabilization agent of low-carbon alcohols cleaning new energy：
Antioxidant component extends oxidation induction period in additive, and dispersant has effectively disperseed sediment particle, prevented filter
It blocks and atomizer pollution, metallic blunt choline work makes deliquescent metal ion activity in oil product reduce, inhibits it to oil product oxygen
Change the catalytic action of reaction, phenol type antioxidant prevents oxidation gum deposit from having special efficacy oil product.Amine type antioxidant to oil product olefin-containing compared with
There is anti-polymerization to generate the complementation of colloid with obvious effects four, playing the role of jointly, which improves oil product, stabilizes more.
(12) cosolvent of low-carbon alcohols cleaning new energy：
It, can be directly as fuel combustion when low-carbon alcohols cleaning new energy is added in additive.
Ketone in additive and higher alcohols are conducive to low-carbon alcohols cleaning new energy matrix and dissolve each other, the ethers in additive
Be conducive to improve calorific value, advantageously reduce oil consumption.Meanwhile two kinds of auxiliary materials in additive solve cold caused by the latent heat of vaporization open
Move difficult problem.Alcohol in additive and ketone advantageously account for vapour lock problem.
In use due to low-carbon alcohols cleaning new energy itself, cleaning action is played to oil circuit, can often cause automobile
The problem of greasy dirt fast-falling accumulated for a long time in fuel tank, oil pump and filter restriction are caused, so that automobile can not start.Addition
Two kinds of raw materials in agent have the function of making inner wall of oil tank to generate thin film, prevent the greasy dirt fast-falling in oil circuit, this is thin
Film has slow releasing function, greasy dirt can be made slowly to dissolve, eventually become scattered paste shape, scattered paste shape substance is slowly dissolved, finally by
