The invention relates to a process for the production of dichlorohydrin which comprises reacting allylchloride, water and chlorine in a reaction zone to form an aqueous solution comprising dichlorohydrin and chlorinated organic byproducts, and contacting the aqueous solution with 1,2,3-trichloropropane to obtain an aqueous layer comprising the dichlorohydrin and an organic layer comprising the trichloropropane and chlorinated organic byproducts, separating both layers and recovering the dichlorohydrin.

Production of dichlorohydrin

A process for the removal of hydrogen from a mixture of hydrogen and one or more organic compounds, which comprises contacting the mixture with a molecular sieve containing a reducible metal cation, said molecular sieve being selectively permeable to hydrogen.

Process for removing hydrogen from the presence of organic compounds

An aldehyde is prepared by passing an aromatic carboxylic compound or an aliphatic carboxylic compound having at most one .alpha.-hydrogen atom in the acyl group, in the presence of hydrogen at elevated temperature over a catalyst comprising at least 25% w of iron oxide expressed as Fe.sub.2 O.sub.3, calculated on the total catalyst.

Process for the preparation of an aldehyde

Process for the co-production of ketones and mono-olefins from secondary alcohols and conjugated di-olefins in which dehydrogenation of the secondary alcohol and hydrogenation of the conjugated di-olefin are effected by contacting a mixture of the secondary alcohol and the conjugated di-olefin with a heterogeneous copper-containing catalytic system. The process is very useful for the co-production of methyl ethyl ketone and n-butenes from sec-butanol and butadiene at low temperatures (e.g. between 90.degree. C. and 130.degree. C.).
