Abstract
A process of preparing 3,3-bis (chloromethyl) oxacyclobutane comprises reacting a dispersion of pentaerythritol trichloride or an ester thereof in aqueous medium with an alkali metal hydroxide or an alkaline earth metal hydroxide at a temperature of 90 DEG to 170 DEG C., the concentration of dissolved hydroxide in the aqueous phase not exceeding 70 per cent. The ester may be pentaerythritol trichloride monoacetate, propionate or hydrogen sulphate. The hydroxide may be sodium hydroxide, potassium hydroxide, calcium hydroxide or barium hydroxide. Wetting or dispersing agents, such as sodium stearate, alkylarylsulphonates and nonylphenol ethylene oxide adduct, may be present. The temperature is preferably from 100 DEG to 130 DEG C., and the concentration of dissolved hydroxide is preferably from 10 to 50 per cent. Examples of the process are given.
