Abstract

1480636 Straight chain primary alcohols and their esters CHEMISCHE WERKE HULS AG 18 Sept 1974 [19 Sept 1973 15 May 1974] 40615/74 Heading C2C An ester of a straight chain C 6 -C 20 primary alcohol with a C 4 -C 20 monocarboxlyic acid is prepared by reacting a C 6 -C 20 straight chain 1-chloroalkane and/or 1-bromoalkane with an alkali metal salt of the monocarboxylic acid, in the presence of at least 1 mole per cent of free monocarboxylic acid relative to the alkali metal salt of the monocarboxylic acid, at a temperature of at least 150‹ C. The free acid preferably but not essentially corresponds to that forming the product ester; and alcohol for example one corresponding to that forming the ester, may also be present. The ester may then be saponified, e.g. in an alkaline medium, and the free C 6 -C 20 primary alcohol isolated; for isolation of the alcohol, a residue from an oxoalcohol or from the Alfol process, the residue being of higher boiling point and easily separated by distillation from the required alcohol, may be added to the product of saponification, the required alcohol distilled off and the residual solution of the monocarboxylic acid used for further ester formation. A mixture containing predominantly 1- chloroalkanes for use as starting material may be obtained by chlorination of one or more straight chain C 6 -C 20 paraffins, partial dehydrochlorination removal by distillation of resultant olefins, unreacted paraffins and impurities, and fractionation of the sump product to obtain the 1-chloroalkanes. 1-Bromoalkanes may be obtained by hydrobromination of α- olefins under free radical conditions, by cleavage of ethers with hydrobromic acid or by degradation of carboxylic acids or their salts. Acids used are isobutyric, caprylic, 2-ethylhexanoic, a C 8 /C 10 mixture and behenic; comparison examples using acetic and propionic acids are also given; in general the sodium salt is used, with some free acid present.
