Abstract
The invention discloses a methanol gasoline additive. The methanol gasoline additive comprises methanol and modifying agent in a weight ratio of (92-97):(3-8), wherein the modifying agent comprises the following materials in percentage by weight: 15-25% of isobutanol, 10-20% of oleic acid, 18-22% of dimethyl carbonate, 7-13% of dimethyl ether, 1-3% of methyl tertiary butyl ether, 12-18% of diethyl ether, 9-11% of acetone, 3-7% of tertiary butanol, 0.8-1.2% of hexamine, and 1.6-2.4% of benzotriazole. The invention further discloses a preparation method for the additive. According to the methanol gasoline additive and the preparation method for the additive provided by the invention, the mutual synergistic effect of a plurality of organic substances is adopted, so that the additive effectively disperses various hydrocarbons in the finished product gasoline, the combustion process is complete and sufficient for reducing the oil consumption by about 6.5-9.8%, reducing the content of CO in the exhausted tail gas by about 40%, and reducing the content of the hydrocarbon compound by about 60%.
Description
Technical field
The present invention relates to the gasoline dope technical field, methanol gasoline additive especially, and preparation method thereof.
Background technology
Improve the motor spirit cleanliness factor and gasoline is fully burnt, it is very problems of concern of current chemical field and automotive industry, particularly in the gasoline that China uses at present, the catalytically cracked gasoline proportion is also quite high, so colloid, paint film and sedimental problem that gasoline oxidation generates are also more serious.Address this problem, except refinery production reduces the peace and quiet gasoline of olefin(e) centent, adding additive in gasoline product also is domestic and international chemical industry method commonly used; Although have a lot of reports to mention gasoline dope, all can not effectively reduce specific gasoline consumption.
Summary of the invention
The present invention is directed to deficiency, propose a kind of methanol gasoline additive, can effectively improve the rate of combustion of gasoline product, reduce its consumption, and carbon monoxide content and hydrocarbons content are low in the emission.The preparation method of this methanol gasoline additive has also been proposed, easy and simple to handle.
In order to realize foregoing invention the first purpose, the invention provides following technical scheme: a kind of methanol gasoline additive, by weight ratio 92～97: 3～8 methyl alcohol and properties-correcting agent form, and wherein properties-correcting agent is made of the material of following weight ratio:
Preferably, the weight ratio of the material of formation properties-correcting agent is as follows:
Preferably, the weight ratio of methyl alcohol and properties-correcting agent is 95: 5.
In order to realize foregoing invention the second purpose, the invention provides following technical scheme: a kind of preparation method of as mentioned above methanol gasoline additive comprises:
(1), measures by weight each material;
(2), each material of step (1) is added in reactor, be heated to 50～55 ℃, react 30～45 minutes, filtration, clear liquid is methanol gasoline additive.
Compared with prior art, the present invention adopts gas chromatography matter mutually to act synergistically, so that this additive scatter various hydro carbons in the gasoline product effectively, thereby guarantee combustion processes fully and completely, reach and reduce oil consumption about 6.5～9.8%, the CO content decrease about 40% in the emission, and hydrocarbons content descends about 60%.
