A process for preparing an aromatic propargyl ether, preferably bispropargyl ether, from phenolic compounds comprising vigorously stirring a propargyl halide, preferably propargyl chloride, with a phenolic compound, such as bisphenol A, in an aqueous sodium hydroxide solution at a temperature of from about 0.degree. C. to about 100.degree. 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 98% purity in yields ranging from 85 to 97% of theoretical.
从酚类化合物中制备芳香丙炔醚,最好是双丙炔醚的工艺过程,包括在水合氢氧化钠溶液中将丙炔卤化物(最好是丙炔氯化物)与酚类化合物(如双酚A)剧烈搅拌在温度约0°C至约100°C的条件下,同时加入相转移催化剂(如四丁基溴化铵)。然后将混合物过滤以回收固体产物。该产物经水和丙醇洗涤。该工艺提供了产物,其纯度大于98%,产率在85%至97%的理论产率范围内。
