Abstract: The improved prepn. of Aldehydes are prepd. by the hydroformylation of olefinically unsatd. cpds., using catalysts contg. Co, by effecting the reaction also in the presence of noble metal catalysts selected from cpds. of Pt, Rn or Pd. The formation of isoaldehydes and polymsn. of starting materials, e.g. styrene is repressed. Rh catalysts are not required.

Abstract: The novel prepn. of diethyl ketone comprises reacting ethylene, CO and H2O at 150-300 degrees C/100-350 atmos. press. in the presence of an inert solvent and a Ru halide or its hydrate as catalyst. Diethyl ketone is obtained in high yields and purity, almost free from by products and contg. only small amts. of ethane. The reaction is smooth. The catalyst is specif RuCl3 or RuCl3.3H2O.

Abstract: Ethyl esters of 3-4C unsatd. monocarboxylic acids are prepd. by reaction of ethylene with the unsatd. acid (I) in presence of acid catalysts at 70-250 degrees C and 5-500 atmos., in presence of a satd. carboxylic acid (II) and/or its ethyl ester. High reaction rates are achieved, without polymerisation occurring. Distillative sepn. of the ethyl ester of I requires low energy consumption. Acid catalysts include (poly)phosphoric acids, HCl, H2SO4 and/or sulphonic acids, opt. on carriers. Strong acid cation-exchangers or de-cationised zeolites are pref. the amt. of catalyst is 0.1-20 (1-10) wt.% Cu, Ag, Ru, Pd or Pt, as metals or complexes, may be used as promoters, in amt. of 0.1-20 (0.5-5) wt.% w.r.t. acid catalyst. Mono- or di-carboxylic acids which are liquid at reaction temp. and which easily form ethyl esters which can be trans-esterified, are used as II, e.g. beta-ethoxy- or beta-acetoxy-propionic acid or acetic acid. Pref., the b.pt. of the thyl ester of II is higher than that of the ethyl ester of I. Halogenated acids, e.g. chloroacetic aced are pref. Reaction is pref. continuous, esp. by the trickle process. The reaction mixt. esp. contains 2-60 (10-30) wt.% I.
