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 DEG C. to about 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 98% purity in yields ranging from 85 to 97% of theoretical. |
