PREPARATION METHOD OF GLYCIDYL TERTIARY CARBOXYLIC ESTER

摘要

The present invention provides a preparation method of glycidyl tertiary carboxylic ester. The synthesis is performed in two steps: first, making the tertiary carbonic acid and a halogenated epoxy compound react under a catalyst to produce tertiary halogenated alcohol ester; after removing hydrogen halide from the tertiary halogenated alcohol ester, forming the glycidyl tertiary carboxylic ester. In the first step of preparing the glycidyl tertiary carboxylic ester through synthesis, the reaction between the tertiary carbonic acid and the halogenated epoxy compound is only performed in the existence of water and the catalyst, and the water comprises water added in advance in the reaction. The present invention significantly increases the product output in the unit volume, and is particularly suitable for industrial production of glycidyl tertiary carboxylic ester having the low cost, high purity, low color and stable color.
