| titleOfInvention | A kind of industrialized process for preparing of high-optical-purity acetyl group tetrahydrofuran |
| abstract | The invention discloses a kind of industrialized process for preparing of high-optical-purity acetyl group tetrahydrofuran; belong to the field of chemical synthesis, using tetrahydrofuran formic acid as raw material, tetrahydrofuran formyl chloride is obtained through chlorination; it is condensed again with Maxwell acid, target compound acetyl group tetrahydrofuran is obtained through hydrolysis；The preparation method of the present invention, cost of material is low, it is not necessary to use RMgBr, and product characteristics are stable, and purity is up to more than 98%, and optical purity is up to more than 99%, and yield is up to more than 70%；This method have passed through the production checking of actual industrial metaplasia, and steady quality, reaction condition is gentle; safe operation is reliable, and dichloromethane is recyclable to be applied mechanically, technique favorable reproducibility; prepare cost low, be a kind of industrialized process for preparing of reliable high-optical-purity acetyl group tetrahydrofuran. |
