Abstract

A method of preparing an ester of the formula RCOOR'SO3M, where R is an aliphatic hydrocarbon radical having 7 to 19 carbon atoms, R'is a divalent aliphatic radical containing 2 to 4 carbon atoms or a radical divalent aryl or alkylaryl containing from 6 to 8 carbon atoms, and M is an alkali metal cation, by direct esterification of a HOR'SO3M hydroxy sulfonate with an aliphatic acid R.COOH, characterized in that the esterification It is carried out in two phases: a first phase comprising reacting with the hydroxysulfonate a first acid containing a higher proportion of C8-C14 acids, the amount of the first acid being between approximately 0.8 and 1.1 mol per mole of hydroxy-sulfonate; and a second phase comprising the addition to the reaction product of the first phase of a second acid consisting essentially of C14-C20 acids and termination of the esterification; the total amount of the first and second acids being at least about 1.2 moles per mole of hydroxy sulfonate.
