Abstract: - 10 - O.Z. 0050/36690 5-Membered, 6-membered or 7-membered cyclic imines are prepared by hydrogenating a C2-C4-alkanedinitrile in the liquid phase, at from 180 to 360.degree.C and under superatmospheric pressure, in the presence of a catalyst, by a process in which an iron catalyst obtained by reduction of an iron oxide with hydrogen at 500.degree.C is used.

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.
