Abstract: Process for producing aldehydes of formula (I) by hydrogenation of esters of formula (II), comprises gas-phase reaction of the ester with a 2-200 molar excess of hydrogen at 200-450 deg C in the presence of a heterogeneous catalyst, with recycle of unreacted hydrogen and ester. By-produced alcohol R'OH is removed from the recycle stream at least to the extent that the molar ratio of alcohol to ester in the reaction mixture is no more than 1:1. RCHO (I) RCOOR' (II) R = an aliphatic, cycloaliphatic, aromatic or araliphatic group that is optionally substituted and/or contains heteroatoms, and R' = residue of a 1-10C alcohol

Abstract: The invention concerns catalysts suitable for preparing aliphatic alpha-, omega-aminonitriles by partial hydrogenation of aliphatic dinitriles, containing: (a) metallic cobalt, a cobalt compound or their mixtures, the metallic cobalt portion being between 20 and 100 wt % relative to (a); (b) between 10 and 70 wt %, relative to (a), of metallic iron, iron oxide, a further iron compound or their mixtures, the iron oxide portion being between 20 and 100 wt % relative to (b); and (c) between 0 and 1 wt %, relative to (a), of a compound based on an alkali metal, alkaline earth metal or zinc.

Abstract: Production of an alkylene oxide (A) involves (a) epoxidation of the corresponding olefin with aromatic peroxycarboxylic acid (I) and separation of the resultant aromatic carboxylic acid (II), (b) hydrogenation of (II) to the corresponding aldehyde (III) and (c) oxidation of (III) with oxygen (or gas containing oxygen) to (I), which is re-used for the epoxidation. The novel feature is that (i) (II) and/or (III) lost in the cycle is replaced by compounds obtained by oxidation of the parent alkyl-aromatics, (ii) phenolic by-products in the aldehydes are removed before stage (c) or (iii), if the olefin has 2-6C, it is prepared by dehydrogenation of a corresponding 2-6C hydrocarbon.
