Butyl acrylate Use and Manufacturing

Methods of Manufacturing

Acrylic ester production methods are acrylonitrile hydrolysis, β-propiolactone method, Lei Pei method and modified Lei Pei method , cyanoethanol and propylene direct oxidation method.1 Cyanoethanol method:Use chlorohydrin and sodium cyanide as raw materials, after rhe reaction to get cyanide alcohol, cyanide ethanol and in the presence of sulfuric acid hydrolysis of acrylic acid2 Acrylonitrile hydrolysis method:As a source of acrylonitrile is rich, we developed the use of acrylonitrile as raw materials to produce acrylic acid.Now the method of industrialization is Societe Ugine and Standard Oil Co(O-hio) .Acrylonitrile with sulfuric acid heated to 90 ℃ Hydrolysis of acrylonitrile to acrylamide, sulfate esters further esterified acrylic acid .In recent years, a patent report, acrylonitrile as raw material, using one-step production, ester yield up to 95%.3 Propiolactone method:Acetic acid (or acetone) as raw materials, triethyl phosphate catalyst at 625-730 ℃ pyrolysis generated diketene And then with the anhydrous vinegar in the presence of NAHCO3 or BF3 catalyst at 25 ° C gas phase reaction to produce β-propiolactone If the desired product is acrylic acid, the propiolactone is contacted with the hot 100% phosphoric acid to form isomeric acrylic acid , If the desired product is an acrylic ester, the crude propiolactone can be directly reacted with the corresponding alcohol and sulfuric acid without purification.4 Lei Pei method and modified Lei Pei method:During the Second World War, Reppe found in the research work of two ways to acetylene, carbon monoxide and water or alcohol synthesis of acrylic acid or acrylic ester.The

Uses

Mainly used to make synthetic resins, synthetic fibers, synthetic rubbers, plastics, coatings, adhesives, etc. Acrylic acid and its esters are widely used in industry. In the process of use, acrylic esters are often polymerized into polymers or copolymers. Butyl acrylate (as well as methyl, ethyl, 2-ethylhexyl) is a soft monomer, which can be combined with various hard monomers such as methyl methacrylate, styrene, acrylonitrile, vinyl acetate, etc., and functional Monomers such as hydroxyethyl (meth)acrylate, hydroxypropyl ester, glycidyl ester, (meth)acrylamide and base derivatives are copolymerized, crosslinked, grafted, etc., to produce more than 200-700 acrylic resins Products (mainly emulsion type, solvent type and water-soluble type) are widely used in coatings, adhesives, acrylic fiber modification, plastic modification, fiber and fabric processing, paper treatment agents, leather processing, and acrylic rubber. Uses It is used as a monomer of polymers and resins and as intermediates in organic synthesis. It is produced in industry by direct esterification of acrylic acid and butanol under sulfuric acid catalysis. It is a monomer for the synthesis of acrylic resins, mainly used in the preparation of coatings, adhesives, resins and acrylic rubbers. Butyl acrylate is a soft monomer and can be combined with various hard monomers such as methyl methacrylate, styrene, acrylonitrile, vinyl acetate, etc. and functional monomers such as hydroxyethyl (propyl) acrylate and methacrylate. (C) esters, glycidyl esters, acrylamides, etc. are copolymerized to make acrylic resins with different properties.
