| titleOfInvention | Synthesis of oxygenated organic compounds |
| abstract | Oxygenated organic compounds are obtained by reacting olefines in the liquid phase with carbon monoxide and hydrogen at elevated temperature and pressure, the reaction being carried out in the presence of between 0.1 and 5 per cent by volume, based on the olefins, of an aqueous solution of a water-soluble salt of cobalt, iron or nickel and in the presence of up to 2.5 per cent by weight based on the olefin of an emulsifier, preferably an amount of up to 2 per cent by weight of the olefin. The preferred emulsifiers are non-ionic emulsifiers such as the polyether alcohols but other emulsifiers such as soaps, alkyl sulphates, sulphonates, glycol esters, sulphonated castor oil, monosulphates of mono-glycerides, alkyl aryl sulphonates or the amine salts of fatty acids may be employed. The water-soluble salt of cobalt, iron, or nickel may be an inorganic salt such as the chloride, nitrate, iodide or bromide or an organic salt such as the acetate, propionate, benzoate or naphthenate. The synthesis may be carried out batchwise or continuously and under conventional conditions for the Oxo process and the product may be hydrogenated to convert the aldehydes obtained to the corresponding alcohols. In an example the reaction is carried out with a C7 olefin fraction (obtained by fractionation of a product obtained by the polymerization of propylene and a mixture of equal volumes of hydrogen and carbon monoxide at 320 DEG F. and 2700-2900 pounds per square inch pressure and a table is given comparing the reaction rates when a saturated aqueous solution of cobalt acetate in a concentration of 2 per cent by volume of olefin is employed as catalyst in the presence of various concentrations of a polyether alcohol as emulsifier. Comparative results are also given when cobalt oleate and cobalt metal are used and when cobalt acetate solution is used in the absence of an emulsifier. Experiments are also described which show that good yields of alcohol are obtainable when the aqueous solutions are employed as catalyst in the absence of an emulsifier but in these cases the reaction rate is lower. In these experiments diisobutylene is reacted with a gas mixture containing hydrogen and carbon monoxide in the volume ratio of 1.2 : 1 at 272 DEG F. and 300 lb. per square inch pressure and using an aqueous solution of cobaltous chloride hexahydrate and of ferric chloride hexahydrate respectively as catalyst, the products being then hydrogenated over a nickel on kieselguhr catalyst at 350 DEG F. and 2700 lb. per square inch hydrogen pressure to form C9 alcohols. |
