<p>In the processing of residues contg. carboxylate salts, which occurs in the large-scale synthesis of alcohols by hydroformylation of C2H4 and C3H6, following by hydrogenation of the aldehyde formed initially, the residues are treated with strong aq. mineral acids, in an amt. to give an aq. phase with pH 2-6, and the total amt. of water present in this mixt. is 1.5-4 times the amt. of bound carboxylic acid: and the aq. and org. phases are sepd. and further processing of the residues is carried out in known manner. Simultaneous redns. are achieved in processing costs by economical processing and in environmental pollution. The org. phase contains most of the org. acids (n- and iso-C3H7.COOH and C2H5.COOH), which can be isolated economically and used in numerous org. syntheses.</p> |
