Abstract
The invention discloses a preparation method of a 3-furfural product. A palladium catalyst, a heteropoly acid catalyst and a Lewis acid catalyst are selected and dissolved in a three-neck bottle containing 1 mol/L solvent, and water-bath heating is conducted till the temperature ranges from 40 DEG C to 90 DEG C; alpha, beta-unsaturated carboxylic ester and aliphatic aldehydes are selected and mixed with each other, a mixed solution is dropwise added into a flask, and stirring reflux reaction is conducted at the temperature ranging from 40 DEG C to 90 DEG C; after reaction is completed, an extraction agent is added for separation, 3-furoic acid esters are obtained through reduced pressure distillation, and the 3-furfural product is obtained after a reaction is conducted by adding a reducing agent into the flask. According to the preparation method of the 3-furfural product, the alpha, beta-unsaturated carboxylic ester, the aliphatic aldehydes, the heteropoly acid catalyst and the like which are all frequently-used chemical reagents are adopted, the cost is low, operation is convenient and easy to carry out, bulk production can be conducted, the pollution to the environment is less, and the reaction is environmentally friendly; meanwhile, the 3-furfural product is an intermediate with wide application prospect, and synthesis and applications of down-stream products of the 3-furfural product has the wide application prospect.
Description
Technical field
The invention belongs to the synthesis technical field of the pharmaceutical intermediate of 3-furfural and substituent thereof, be specifically related to a kind of preparation method of 3-chaff aldehyde product.
Background technology
3-furfural, has another name called 3-furtural, and furans lopps intermediate can be used as the intermediates such as volatile oil, makeup, fuel, photosensitizers, sterilant or medicine, and application prospect widely.The method of current existing synthesis furan derivatives is: by 1, the intramolecular cyclization of 4 diketone or be that starting raw material synthesizes with α halogenated ketone with β ketone acid (ester), because the catalyzed reaction of transition metal is widely used in the synthesis such as Furan and its derivatives, heterogeneous ring compound, the shortcoming of these reactions applies special chemical reagent, the precursor not easily obtained or needs more synthesis step.In addition, research report at home for 3-furfural synthetic method is fewer, and the main method of producing 3-furfural is backward and big for environment pollution, for this reason, seek the processing method that a kind of reaction conditions is gentle, environmental protection high yield synthesizes 3-furfural, there is potential huge environment and economy benefit.
Summary of the invention
The object of the invention is Problems existing in the synthetic method for existing 3-chaff aldehyde product, provide that a kind of raw material is cheap and easy to get, synthesis step is few, separating-purifying is easy, the synthetic method of high-quality.
In order to solve the problems of the technologies described above, the present invention realizes in the following manner:
A preparation method for 3-chaff aldehyde product, its concrete processing step and condition as follows:
1) choose the palladium catalyst of 0.01 ~ 0.1 part (being amount of substance mark herein and below), the heteropllyacids catalyzer of 0.01 ~ 0.1 part, the lewis acid catalyst of 0.01 ~ 1 part be dissolved in and be equipped with in there-necked flask that concentration is 1mol/L solvent, and by solvent in heating in water bath to 40 ~ 90 DEG C;
2) α of 1 ~ 5 part is chosen again, beta-unsaturated carboxylic acid ester mixes mutually with the fatty aldehydes of 3 ~ 5 parts, draw mixing solutions and dropwise drop to step 1) in there-necked flask in, remain in 0.5 ~ 5h and dropwise, and then under 40 ~ 90 DEG C of conditions stirring and refluxing reaction 1 ~ 8h;
3) treat step 2) in reaction carry out after, add the extraction agent of 1 ~ 5 part, under 0.40 ~ 0.55 normal atmosphere, 3-furoate class is obtained through underpressure distillation after extracting and separating, in the flask of 3-furoate class, add the reductive agent of 0.5 ~ 3 part, reduction reaction obtains 3-chaff aldehyde product.
α described in the present invention, beta-unsaturated carboxylic acid ester has following structure:
Wherein R
1for groups such as hydrogen base, methyl or ethyls, R
2for the group such as methyl or ethyl, if R
1for hydrogen base, then final product is 3-furfural, if R
1for other bases, then final product is 5 replacement 3-furfurals;
Fatty aldehydes described in the method has following structure:
Wherein R
3for groups such as methyl, ethyl or propyl group.
Further, step 1) described in the kind of palladium catalyst be one or more in palladium carbon, Palladous chloride, Palladous nitrate and palladium; The kind of heteropllyacids catalyzer is one or more in phosphorus molybdenum vanadium heteropolyacid, phospho-molybdic acid heteropolyacid, tungsten vanadium heteropolyacid and tungsten acid heteropolyacid; The kind of lewis acid catalyst is one or more in iron(ic) chloride, cupric chloride, Cerium II Chloride and zinc chloride.
Step 1) described in solvent be one or more in hydrochloric acid, glacial acetic acid, methyl alcohol, ethanol, propionic acid, Virahol, tetrahydrofuran (THF) and pyridine.
Preferably, step 3) described in the kind of extraction agent be one or more of chloroform, methylene dichloride, sherwood oil and ethyl acetate; The kind of reductive agent is one or more of diisobutyl aluminium hydride, red aluminium, sodium borohydride and lithium aluminum hydride.
Compared with prior art, the beneficial effect that the present invention has: the present invention adopts α, beta-unsaturated carboxylic acid ester, fatty aldehydes and heteropolyacid catalyst etc., be conventional chemical reagent, with low cost, easy to operation, can produce in a large number, environmental pollution is little, belongs to environmentally friendly reaction; The 3-chaff aldehyde product provided of the present invention, is the Synthesis and application of the intermediate that a class has wide application prospect, its derived product, possesses application prospect widely simultaneously.
