| titleOfInvention | A kind of preparation method of methyl 3-methoxyacrylate |
| abstract | The invention relates to a method for synthesizing methyl 3-methoxyacrylate, which is characterized by comprising the following steps: (1) using alcohols as a solvent, under the catalysis of basic substances, diketene and trimethyl orthoformate are prepared in Synthesize methyl 3,3-dimethoxypropionate at 25-90°C, and control the molar ratio of diketene to trimethyl orthoformate and basic substance to be 1:1.0-5.0:0.5-5.0; (2) Reaction After finishing, 3,3-dimethoxy methyl propionate cracks under catalyst action and generates 3-methoxy methyl acrylate, controls the mol ratio 1 of 3,3-dimethoxy methyl propionate and catalyzer: 1.0-5.0, and the reaction temperature is 100-200 o C. The invention has the advantages that the raw materials are cheap and easy to obtain, the synthesis method is simple to operate, the reaction conditions are mild, the equipment requirements are low, and the method is suitable for the needs of industrialized large-scale production. |
