    Abstract: A process for the production of mainly linear aldehydes by hydroformylation of an olefinically unsaturated compound of from two to twenty carbon atoms with carbon monoxide and hydrogen at elevated temperature and superatmospheric pressure in the presence of a cobalt carbonyl complex prepared prior to the hydroformylation from an aqueous solution of a cobalt salt, wherein in a first stage an aqueous solution of a cobalt salt is treated with carbon monoxide and hydrogen at a temperature of from 50* to 200*C and at a pressure of from 100 to 400 atmospheres in the presence of activated carbon, a zeolite or a basic ion exchanger which has been loaded with cobalt carbonyl, the aqueous solution containing cobalt salt and cobalt carbonyl hydride thus obtained and the mixture of carbon monoxide and hydrogen, without releasing the pressure, are extracted at a temperature of 20* to 100*C and at a pressure of 100 to 400 atmospheres in a second stage with a saturated hydrocarbon or the olefinically unsaturated compound used for the hydroformylation (provided they are insoluble in water and liquid under the conditions used), water-insoluble oxo reaction product or hydrogenated oxo reaction product, the aqueous phase is separated and the organic phase containing the carbonyl complex thus obtained and the mixture of carbon monoxide and hydrogen are transferred to a third stage and, after supplying olefinically unsaturated compound (if this has not been used or has only partly been used for extraction in the abovementioned stage) hydroformylation is carried out at a temperature of from 70* to 170*C and a pressure of from 100 to 400 atmospheres. The products of the process are suitable for the production of detergent alcohols and plasticizers and for the production of carboxylic acids and amines.

    Abstract: IMPROVED PROCESS FOR THE PREPARATION OF SALCOMINE AS WELL AS THE PREPARATION OF TRIMETHYL-p-BENZOQUINONE FROM TRIMETHYLPHENOL USING THE RESULTANT SALCOMINE of the Disclosuore Improved process for the preparation of salcomine useful as an oxidation catalyst for the oxidation of alkylated phenols to the corresponding alkylated p-benzo-quinones by reacting salicylaldehyde with ethylenediamine in a mole ratio of about 2:1 and a cobalt salt in a liquid reaction medium wherein the reaction medium is a linear or cyclic carboxamide which is disubstituted on the nitrogen, in particular dimethylformamide, and the cobalt salt is cobalt carbonate or with the cobalt hydroxide carbonate, 2 CoCO3.3 Co(OH)2.H2O. Preparation of the salcomine in accordance with the invention offers significant advantages, both in the preparation of the salcomine itself and in the subsequent oxidation of the trimethylphenol to trimethyl-p-benzoquinone utilizing the salcomine.

    Abstract: Continuous production of carbonyls of metals of Group 8 of the Periodic Table by treatment of solutions of appropriate metal salts with an excess of carbon monoxide and hydrogen at temperatures of 50 DEG to 200 DEG C and at pressure of 50 to 500 atmospheres gauge in the presence of activated carbon, a zeolite or a basic ion exchanger which is loaded with the corresponding metal carbonyl. Solutions of metal carbonyls obtained by the process are suitable as catalyst solutions for carbonylatiion reactions, particularly for hydroformylation reactions.
