Abstract
A process for the production of oil-soluble sulfonates from a gas oil such as a vacuum gas oil. Water-soluble sulfonic acids are separated from the effluent of the sulfonation zone, and the remainder of the effluent is then passed through a saponification zone to produce oil-soluble sulfonates which are then recovered. The remaining hydrocarbons are fractionated, with the resultant heavy fraction being passed through a reforming zone to produce additional aromatics which are then recycled to the sulfonation zone.
