| titleOfInvention | Preparation method of 3-alkoxy alkyl propionate |
| abstract | The invention belongs to the technical field of chemical synthesis and provides a preparation method of 3-alkoxy alkyl propionate. The method is characterized by using solid alkali as a catalyst and alkyl acrylate and lower alcohol as raw materials to carry out heterogeneous catalytic alkoxylation reaction, and comprises the steps that an alkoxylation reaction product enters a light component removal rectifying tower to be separated, and lower alcohol and an alkyl acrylate light component, which are recovered from the tower top, are cycled into the step of alkoxylation reaction; a heavy component mainly containing a product 3-alkoxy alkyl propionate is obtained in a tower reactor; the heavy component material in the light component removal rectifying tower reactor is separated by a refined rectifying tower, the product 3-alkoxy alkyl propionate is obtained at the tower top and a few high-boiling substances are obtained in the tower reactor. The preparation method has the beneficial effects that after being separated and recovered by the rectifying tower, the used raw materials and solid alkali serving as the catalyst can be directly put into reaction again without being reprocessed, thus greatly improving the utilization efficiency of the raw materials and the catalyst, reducing the production cost and avoiding environmental pollution. |
