PREPARATION METHOD OF GLYCIDYL TERTIARY CARBONIC ESTER

摘要

The present disclosure provides a preparation method of glycidylester of tertiary carbonic acid. The synthesis is performed in two steps: first, the tertiary carbonic acid reacts with a halo substituted epoxide under a catalyst to produce tertiary carbonic halo substituted alcohol ester; after dehydrohalogenation of the halo substituted alcohol ester of tertiary carbonic acid, the glycidylester of tertiary carbonic acid is formed. In the first step of preparing the halo substituted alcohol ester of tertiary carbonic acid through synthesis, the reaction between the tertiary carbonic acid and the halo substituted epoxide is only performed in the existence of water and the catalyst, and the water comprises water added before the reaction. The present disclosure significantly increases the product output in the unit volume, and is particularly suitable for industrial production of glycidylester of tertiary carbonic acid having the low cost, high purity, low color and stable color.
