A PROCESS FOR THE SELECTIVE ESTERIFICATION OF TERTIARY ALCOHOL BY AN ACID ANHYDRIDE USING A REUSABLE SOLID CATALYST

摘要

A process for the selective esterification of a tertiary alcohol by contacting a mixture of tertiary alcohol and an organic acid anhydride optionally in presence of a non aqueous solvent with the fine particles of solid catalyst in a stirred batch reactor provided with a reflux water condenser at atmospheric pressure at the reaction conditions, the reaction temperature is below about 80°C; and the reaction period is in the range from about 0.1 h to about 50 h, removing the solid catalyst from the reaction mixture by filtration; and reusing the separated solid catalyst for subsequent batch of the process.
