发明名称 PROCESS FOR MAKING PROPARGYL ETHERS OF HYDROXYAROMATIC COMPOUNDS
摘要 A process of preparing an aromatic propargyl ether, preferably bispropargyl ether, from hydroxyaromatic compounds comprising vigorously stirring a propargyl halide, preferably propargyl chloride, with a hydroxyaromatic compound, such as bisphenol A, in an aqueous sodium hydroxide solution at a temperature of from 0 DEG C to 100 DEG C, in the presence of a phase transfer catalyst such as tetrabutylammonium bromide. The mixture is then filtered to recover a solid product. That product is washed with water and propanol. This process provides a product having greater than 95 percent purity in yields ranging from 85 to 97 percent of theoretical.
