AI Technical Summary

Technical Problem

The existing preparation methods for fluorocarbon alcohols are complex and have a monopoly on the market. They lack efficient and easy-to-produce methods, resulting in high production costs and insufficient market supply.

Method used

Hexafluoropropylene oxide is used as raw material, and specific catalysts and solvents are used to adjust the polymerization under controlled temperature and pressure to generate dimers and trimers, which are directly converted into methyl ester, and then reduced and distilled to obtain high-purity Fluorocarbon alcohol.

Benefits of technology

The efficient and low-cost preparation of fluorocarbon alcohols is achieved. The product purity reaches 99.7%, which is suitable for large-scale production. Selectivity control is achieved by adjusting the ratio of catalyst and solvent.

Abstract

The invention discloses a preparation method and application of fluorocarbon alcohol. According to the preparation method disclosed by the invention, hexafluoropropylene oxide is used as a raw material, a dimer and a trimer are generated by carrying out adjusting polymerization on the hexafluoropropylene oxide at a proper reaction temperature under the action of a catalyst solvent, the dimer and the trimer are directly converted into methyl ester without separation, dimer methyl ester and trimer methyl ester are obtained through rectification, dimer fluorocarbon alcohol and trimer fluorocarbon alcohol are obtained by respectively reducing the dimer methyl ester and the trimer methyl ester, and finally, the rectification is carried out again, so that the purity is up to 99.7 percent.
