The invention comprises a process for making 3 : 31 - bis - (chloromethyl) cyclo - oxabutane (3 : 31 - bis - chloromethyl - oxetane) by the action of excess of alkali hydroxide on pentaerithritol trichlorohydrin or its monoacetate in an inert organic solvent so that the water present and formed is removed azeotropically. Highly concentrated alkali solutions and potash are advised. In examples, the pentaerithritol trichlorhydrin is dissolved in benzene and treated with excess of strong aqueous potash while distilling a mixture of solvent and water; a similar process is performed with the monoacetate.
