METHOD FOR PRODUCTION OF VINYL FURFURYL ETHERS Russian patent published in 2009 - IPC C07D307/12 C07D307/42

Abstract RU 2359965 C1

FIELD: chemistry.

SUBSTANCE: invention is related to improved method for preparation of vinyl furfuryl and vinyl tetra hydrofurfuryl ethers by vinylation of appropriate alcohols by acetylene at atmospheric pressure of acetylene in medium of DMSO (dimethylsulfoxide) at the temperature of 70-100°C, for 3.5-6 hours, in presence of sodium hydroxide.

EFFECT: process simplification due to implementation of process at atmospheric pressure of acetylene and moderate temperature and increased yield of target product up to 90%.
