| titleOfInvention | Method of producing methyl methacrylate |
| abstract | Process 1 for preparing acetonecyanhydrin with cyanide and acetone, process 2 for producing α-hydroxyisobutyric acid amide by hydrating acetonecyanhydrin, and α-hydroxy with α-hydroxyisobutyric acid amide and methanol Step 3 of preparing methyl isobutyrate and ammonia, step 4 of preparing methyl methacrylate by dehydrating α-hydroxyisobutyrate methyl, and ammonia obtained in step 3 of methanol and solid catalyst in the presence of molecular oxygen A process for producing methyl methacrylate as step 5 of reacting in a phase to produce a gaseous clear liquid.n n n Since methanol is used in step 3, the ammonia generated from the reaction system is removed to easily shift the equilibrium of the reaction to the production side, thereby increasing the conversion rate from alpha -hydroxyisobutyric acid amide to alpha -hydroxyisobutyrate.n n n The use of methanol in process 3 has the additional advantage of efficiently linking the process by eliminating the separation and purification process and reducing the manufacturing cost. |
