<P>PROBLEM TO BE SOLVED: To provide a process for preparing branched olefins, a method of using the branched olefin for making a surfactant. <P>SOLUTION: The process for preparing the branched olefins comprises dehydrogenating an isoparaffinic composition comprising 0.5% or less quaternary aliphatic carbon atoms over a suitable catalyst, which isoparaffinic composition comprises paraffins having a carbon number in a range of from 7 to 35, of which the paraffins at least a portion of molecules is branched, the average number of the branches per paraffin molecule being from 0.7 to 2.5 and the branch comprising methyl and optionally ethyl branches, and which isoparaffinic composition may be obtained by hydrocracking and hydroisomerisation of a paraffinic wax, the branched olefins having a quaternary carbon content of 0.5% or less; and the process of using the olefins for making an anionic surfactant, a nonionic surfactant or a cationic surfactant, in particular a surfactant sulphate or sulfonate, includes converting the branched olefins into the surfactants. <P>COPYRIGHT: (C)2011,JPO&INPIT |
