Methyl Methacrylate (MMA) Ua li cas?

1. Acetone cyanohydrin txoj kev: Acetone cyanohydrin reacts nrog sulfuric acid los tsim methacrylamide sulfate, uas yog hydrolyzed thiab ces esterified nrog methanol kom tau crude methyl methacrylate. Cov khoom nyoos yog tom qab ntawd tau los ntawm kev salting tawm, crude distillation, thiab rectification. Acetone cyanohydrin feem ntau yog npaj los ntawm sodium cyanide.

2. Isobutylene txoj hauv kev: Isobutylene raug ob-theem oxidation nrog huab cua nyob rau hauv lub xub ntiag ntawm molybdenum catalyst. Isobutylene yog thawj zaug oxidized rau methacrylaldehyde, thiab tom qab ntawd ntxiv oxidized rau methacrylic acid. Methacrylamide yog esterified nrog methanol kom tau methyl methacrylate. Tsis ntev los no, ib qho - cov txheej txheem oxidation tau tsim. Isobutylene ncaj qha oxidized rau methacrylic acid siv N₂O₄ ua cov oxidant thiab K₂CO₃ lossis Mr₁O₂ ua cov catalyst. Tom qab ntawd nws yog esterified nrog methanol.

3. Propylene Route: propylene, carbon monoxide, thiab methanol raug cov tshuaj tiv thaiv carbonylation los tsim methyl 2-methoxyisobutyrate, uas tom qab ntawd hydrolyzed rau methyl methacrylate thiab methanol.

4. Isobutyraldehyde Ib-Txoj Kev Oxidation: Siv heteropoly acids thiab lawv cov ntsev ua catalysts, isobutyraldehyde yog oxidized nyob rau hauv ib kauj ruam los tsim methacrylic acid, uas yog ces esterified nrog methanol los ua methyl methacrylate.

Methyl Methacrylate (MMA) siv rau dab tsi?

Methyl methacrylate mma yog siv rau hauv kev tsim cov plexiglass, coatings, lubricant additives, plastics, adhesives, resins, ntoo infiltration agents, motor coil penetrants, ion exchange resins, paper polishes, textileprinting and dyeingauxiliaries, tawv kho cov neeg ua hauj lwm, luam ntawv thiab dyeing insulating thiab lwm yam.
