More Information
Summary:Succinimides of aminoaryl sulfonic acid salts provide exceptional detergency, viscosity control and anticorrosion properties to lubricants and greases and to other fluid compositions useful in hydraulic systems. Ammonium, alkylammonium, alkali metal, alkaline earth metal and groups IB, IIB, VIB, VIIB, VIII metal salts of aminoaryl sulfonic acid salts, and the salts of sulfanilic acid in particular, can be reacted with alkenyl or alkylsuccinic anhydride, acid or ester, in which the alkenyl or alkyl group may contain from 8 to about 500 carbon atoms, to yield the products of this invention. These products are understood to be novel. Suitable modifications of the aforementioned are the succinimides of di(aminoaryl sulfonic acid) salts, aniline disulfonic acid salts and corresponding aminonaphthalene sulfonate salts which are also useful in the compositions of this invention.
