METHOD OF OBTAINING PRIMARY ALCOHOLS WITH STRAIGHT CHAINS FROM C4 HYDROCARBON CUTS ABSTRACT OF THE DISCLOSURE A method of preparing primary alcohols, virtually all with a straight chain, in which the molecular proportions are distributed on both sides of a maximum centered at 8 to 16 carbon atoms. It comprises: reaction between a C4 hydrocarbon cut and activated aluminum and hydrogen, during which the concentra- tion of dibutylaluminum monohydride in the reaction medium is adjusted between 20 and 80 molar %, to form a mixture of butyl- aluminum isomers; then a reaction wherein the isobutyl and secondary butyl groups contained in the mixture of isomers are displaced by the 1-butene in a C4 hydrocarbon cut, in at least two reaction zones arranged in series and fed in counter-current flow with the said mixture of butylaluminum isomers and with the C4 hydrocarbon cut; fixing ethylene on the tri-n-butylaluminum thus obtained to a chain length of C8 to C16; then oxidation with a gas containing oxygen and hydrolysis in a mixture of aliphatic primary alcohols. Such alcohols find use in deter- gent compositions after alkoxylation and/or sulphation of such mixtures of primary alcohol.
