ABSTRACT OF THE DISCLOSURE Oil-soluble sulfonated polyols and oil-soluble, partially sul- fonated polyol ester reaction products of C6-C10,000 hydrocarbon substi- tuted C4-C10 dicarboxylic acid materials, e.g. alkenyl succinic anhydride, have been readily produced under reaction conditions characterized by con- ducting said reaction in the presence of at least a sediment-reducing amount of a hydrocarbon soluble C12-C80, preferably a C24-C36, hydrocarbon substituted sulfonic acid whereby sediment resulting from said reaction is markedly reduced to less than 1 vol. % and filtration of the reaction product is facilitated.
