Methyl Methacrylate MMA it is used as monomer of organic glass and also used to manufacture other resin, plastic, paint, adhesive, lubricant, wetting agent of wood and cork, paper Polish, etc.
1. Acetone cyanohydrin route acetone cyanohydrin reacts with sulfuric acid to generate methacrylamide sulfate. After hydrolysis, methyl methacrylate crude product is obtained by transesterification with methanol, and then the finished product is obtained by salting out, crude distillation and distillation. Usually acetone cyanohydrin is made from sodium cyanide. Raw material consumption quota: methyl ketone cyanohydrin 1100 kg/t, sulfuric acid 2100 kg/t, methanol 490 kg/t.
2. Isobutene route Isobutene is oxidized by air in the presence of molybdenum catalyst. Isobutene is oxidized to methacrolein first, and then further oxidized to methacrylic acid. Methyl acrylic acid and methanol are reacted to obtain methyl methacrylate. Recently, another one-step oxidation process has been developed. Isobutene is directly oxidized to methacrylic acid by using N204 as oxidant and k2co 3 or MnO 2 as catalyst. Then, methanol was used for further transesterification.
3. Propylene route propylene, carbon monoxide and methanol undergo carbonylation reaction to generate methyl 2-methoxyisobutyrate, and then decompose into methyl methacrylate and methanol through hydrolysis reaction.
4. Isobutyraldehyde one-step oxidation using heteropolyacid and its salts as catalyst, methacrylic acid is produced by one-step oxidation of isobutyraldehyde, and methacrylic acid is then reacted with methanol to methyl methacrylate.
S24: avoid contact with skin.
S37: use appropriate protective gloves.
S46: in case of accidental swallowing, seek doctor's advice immediately (display product container or label).
R11: very flammable. R43: skin contact will produce allergic reactions. R37/38: it can stimulate respiratory tract and skin.
