Abstract

A process for the production of pentaerythritol trichlorhydrin comprises dissolving pentaerythritol in a reaction product of pentaerythritol and hydrogen chloride, passing hydrogen chloride in at least the amount theoretically necessary through the resultant solution at a temperature between about 170 DEG to 200 DEG C., at a pressure between atmospheric and about 5 atmos, and recovering the pentaerythritol trichlorhydrin thus produced. Specified pentaerythritol -HCl reaction products are the mono-, di- and trichlorhydrins and 5,5-bischlormethyldioxan-1,3 and mixtures thereof. The effluent HCl may be recirculated after condensation of liquid entrained substances. Batchwise and continuous operation is possible. A series of reaction vessels may be used, the pentaerythritol, preferably dissolved in dichlorhydrin, being chlorinated up to about the dichlorhydrin stage in the first vessel at 130-175 DEG C., and converted to the trichlorhydrin at 170-200 DEG C. in subsequent vessel(s). Specification 764,664 is referred to.
