Abstract:
A process for preparing branched alkyl ethoxy sulfate surfactants, comprising the steps of:(a) dimerizing alpha olefins of the formula RCH&boxH;CH2 and Râ€²CH2&boxH;CH2, to form olefins of the formula: wherein in the above formulas R and Râ€² may be the same or different C3 to C7 linear alkyl substituents; followed by either(b) isomerizing the olefins from Step (a) and the subsequent reaction of said isomerized olefins with CO/H2 under Oxo conditions; or directly reacting the olefins from Step (a) with CO/H2 under Oxo conditions; (c) recovering the desired branched alcohols of the formula: (d) ethoxylating the alcohols recovered in Step (c) to produce corresponding alcohol ethoxylates; and (e) sulfating the alcohol ethoxylates to produce corresponding branched alkyl ethoxy sulfate surfactants.
