Function&Application
Crotonic acid is an unsaturated fatty acid, which contains double bonds and carboxyl groups in the molecules. Therefore, it has strong reactivity and has various USES in industry, mainly used in the preparation of various resins, fungicides, surface coatings, plasticizers and drugs.The main application is as raw material for polyvinyl acetate coating.In addition, vinyl-butylenic acid copolymer can be used as a hot fusion adhesive for binding books, as well as as a adhesive for wallpapers and paper, laminates, film developer and electrostatic reprographic fluid components.Crotonic acid series products: butylenic acid amide: obtained by the reaction of oleic acid or its acyl chloride with ammonia.Butyl aniline: obtained by reacting alkyl chloride or butenic anhydride with aniline and used in insecticides.Butyric anhydride: obtained by the reaction of alkyl chloride with sodium butyrate, and also produced by the reaction of butyrate with acetic anhydride or vinyl ketone, used in the preparation of cellulose butyrate and its derivatives.Butylenic acid chloride: obtained by the interaction of alkenic acid with trichlorocarbon or pentachloride, benzoyl chloride or thioyl chloride, used in the preparation of butylenic acid ester and its derivatives.The important butyrate esters are methyl butyrate, ethyl butyrate, butyrate, butyrate, allyl butyrate and allyl butyrate.Valerate, geranide, 2-methylallyl and 2-ethylidene are used in spices, and benzyl ester, methyl cyanide and trimethylidene are pesticides.Crotonic acid peroxide is a catalyst for polymerization of vinyl chloride and vinylidene chloride.Crotonic acid is also used as a synthetic rubber softener.
