ABSTRACT A process for 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°C to 100°C, in the presence of a phase transfer catalyst such as tetrabutylammonium bromide. The mixture id 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.
