ABSTRACT:
An improved method for the direct production and recovery of oil soluble polyvalent metal sulfonates of petroleum hydrocarbons is provided wherein a hydrocarbon feed stock is sulfonated and mixed with water and a hydrocarbon solvent to form a top layer and a bottom sludge layer containing undesirable water soluble sulfonic acids and ions. The top layer is treated with a partition breaking solvent causing it to separate into three phases, a top oil phase, a middle phase containing most of the desired oil soluble sulfonic acids and a lower brine phase containing undesirable water soluble sulfonic acids and ions. The middle phase is directly treated with an oxide or hydroxide of a polyvalent metal without a prior neutralization step to produce neutral oil soluble polyvalent metal sulfonate which can readily be recovered from solution.
