Title: Improvements in and relating to the production of organic oxygen-containing compounds
IPC: C07C45/50
Filed: 1949-09-12
Abstract: Oxygen-containing organic compounds, especially aldehydes, are obtained from an alkene feed containing also di- or poly-enes which may be aliphatic or alicyclic by arranging to have an open chain mono-olefine with at least 4, and preferably at least 6, carbon atoms in the molecule initially in the reactor having dissolved in it as a soluble compound, at least 0.1 per cent. by weight of cobalt, calculated as metal, forming an active carbonylating catalyst therein by passing, under pressure and at elevated temperature, a mixture of CO and H2, in which the partial pressure of CO is at least 50 atmospheres, and preferably with a molar CO:H2 of at least 1:3, carbonylating this material in the same or a different reactor and when the reaction is established effecting carbonylation by introducing continuously into the preformed catalyst solution at elevated temperature and pressure a mixture of CO and H2 having a molar ratio CO:H2 of not less than 3:7 together with liquid alkene feed while maintaining the cobalt concentration in the mixture at not less than 0.1 per cent. of cobalt by weight calculated as metal, by introducing a soluble compound thereof in solution.  An alkene feed comprising mono-olefines of 4-18, particularly 4-12, C atoms is especially suitable.  C6-C8 alpha-alkene mixtures obtained by cracking paraffin wax may be used.  Di-isobutene is specified. Temperatures specified are 130-190, preferably 150-175 DEG C., with pressures of carbonylating gas of 200-300, preferably 250, atmospheres gauge.  Soluble cobalt salts of organic acids are preferred catalysts, e.g. cobalt naphthenate, p  acetate, laurate, hexahydrobenzoate and 3, 5, 5-trimethyl-hexoate.  Di- and poly-enes apparently inhibit carbonylation and their presence is indicated by refractive index or density measurement or infra red spectroscopy. The aldehydes may be hydrogenated to the corresponding alcohols, e.g. at 250 DEG C. and 150 atmospheres gauge using Cu or Ni catalysts especially copper on zinc or chromia.  In an example di-isobutene containing 0.1 per cent. of cobalt as the naphthenate is treated in a reactor at 250 atmospheres gauge and 140-160 DEG C. with a gas comprising 30 per cent. CO and 70 per cent. H2 whilst liquid di-isobutene containing the above catalyst is passed continuously at 0.5 litre/litre/hrs. for 1 to 2 hours when the feed is changed to mixed C6-C8 olefines, from cracked paraffin wax, containing 0.1 per cent. of cobalt as the naphthenate and treatment is continued at 150-170 DEG C. and 250 atmospheres gauge with a gas of the above composition and a gas/liquid ratio of 1,000 cu. metres/cu. metre. the aldehydic products on hydrogenation yielding n-heptanol and 2-methyl hexanol from n-hexene and the corresponding alcohols from heptene and octene.
