Abstract

Octyl alcohols are prepared by reacting a heptene fraction of B.R. 165-215 DEG F. obtained by catalytic polymerization of propene or a mixture thereof with a minor proportion of ethylene and/or normal butenes but free from isobutene, with CO and H2 in the presence of cobalt catalysts, and hydrogenating the aldehyde obtained. The products are dimethyl hexanols with the CH3 groups on different carbon atoms but with the 2- and 6-positions free, and yield on esterification with, e.g. phthalic, adipic, sebacic or phosphoric acid, plasticizers for resins and cellulose derivatives. The olefin feed is freed of any isobutene, e.g. by extracting with 60-70 per cent sulphuric acid, benzene sulphonic acid or cresol, and polymerized with phosphoric acid-kieselguhr. The desired heptene cut is separated and worked up substantially as described in Specification 679,788. With a feed of 90 per cent propene and 10 per cent normal butenes, the alcohols analysed: 3,5-dimethyl hexanol-1, 30; 4,5-dimethyl hexanol-1, 26; 3,4-dimethyl hexanol-1, 18; 3 and/or 5-methyl heptanol-1, 17; and 5,5-dimethyl hexanol-1, 1.5 per cent. Particularly suitable mixtures of dimethyl hexanols for plasticizers contain 15-45 per cent, 3,5-dimethyl, 14-40, 4,5-dimethyl, and 9-27, 3,4-dimethyl isomers. The effect on plasticizer efficiency of varying butene and isobutene content of the feed is illustrated.
