Production method

There are six production methods for acrylic esters: Ethylene cyanohydrin method, high pressure Reppe method, improved Raper method, β-propiolactone method (Goodrich method), hydrolysis of acrylic nitrile and alcohol and propylene oxidation. Now the production methods are acrylonitrile method, β-propiolactone method, raypo method using acetylene as raw material and propylene oxidation method. Among them, propylene oxidation is currently the most widely used method. 1. Acrylonitrile method this method is actually the early cyanoethanol development of law. The first step is to heat and hydrolyze acrylonitrile and sulfuric acid together to generate acrylamide sulfate. The second step is to transedate with alcohol to generate corresponding acrylate and by-product ammonium bisulfate. 2.β-propiolactone method ethenone gaseous phase reaction β-propiolactone with anhydrous formaldehyde in the presence of aluminum trichloride at 25℃. Without purification, it directly reacts with alcohol and sulfuric acid to generate corresponding acrylate. The product of this method has high purity, the by-product and final reaction materials can be recycled, the yield is relatively high, the reaction conditions are simple, and it is suitable for continuous production, but the feed stock cost is relatively high. 3. During the second world war of Raper method, which uses acetylene as raw material, Raper found that there were two methods to make acetylene and carbon monoxide react with water or alcohol to produce acrylic acid or acrylate. One is called stoichiometry and the other is called catalysis. Due to the toxicity of nickel carbonyl, the consumption of nickel and the risk of acetylene at high temperature, these two methods have great difficulties in industrialization. 4. Direct oxidation of propylene propylene the first oxidation of propylene to acrolein, and then further oxidation to acrylic acid. The production of acrylate from acrylic acid is made by continuous transesterification reaction of acrylic acid and corresponding alcohol in the presence of ion exchange resin catalyst at boiling temperature.
