Abstract

1,133,388. Preparation of pure anhydrous dioxolane-(1,3). BADISCHE ANILIN- & SODA-FABRIK A.G. 30 March, 1966 [31 March, 1965], No. 14032/66. Heading C2C. Pure anhydrous dioxolane-(1,3) is prepared by mixing an aqueous solution of formaldehyde or a polymer thereof, with a more than stoichiometric amount of an alcohol of at least 4 carbon atoms which does not have unlimited miscibility with water at ambient temperature and transacetalating the resulting formal with ethylene glycol. The alcohol is preferably butanol or isobutanol in an amount of 200-1000 moles per cent based on the formaldehyde in the presence of a strong acid (1 to 10% by weight) or an acid ion exchanger (1 to 20%) as a catalyst at temperatures between 20‹ and 100‹ C. The water formed may be removed by azeotropic distillation, and the transacetalation is suitably effected by an excess of ethylene glycol (up to 300 moles per cent based on the formal).
