1. Process for the decomposition of mixtures containing formic acid esters or formic acid ester, which are obtained by the reaction of olefines with 4 to 12 carbon atoms with carbon monoxide and hydrogen at 100 to 250 degrees C and 100 to 300 bar in the presence of cobalt catalysts, and after separation of the catalysts and the more easily volatile reaction products, especially the aldehydes, occur as an after-running fraction, characterised in that - the mixtures containing formic acid esters or formic acid ester are fed back into the synthesis stage and - react together with olefine, carbon monoxide and hydrogen in the presence of 2 to 5 wt. % water, based on the initial mixture, - at temperatures of 100 to 180 degrees C. |
