ABSTRACT:
Petroleum sulfonates are manufactured by reacting a hydrocarbon stock with a sulfonating agent and neutralizing the sulfonation product. The hydrocarbon stock is pretreated with hydrogen, in the presence of a NiW or NiMo catalyst, under specified conditions: its sulfur content is decreased by at least 50%, but its aromatic hydrocarbon content is decreased by not more than 35%, so that the aromatic hydrocarbons content remains at least 20% b.w. after completion of the pretreatment.
