ABSTRACT:
A reaction product of detergent-dispersant properties in lubricating oil prepared by the sequential method of (1). reacting polyalkene of from 30 to 300 carbons with maleic anhydride to form alkenyl succinic anhydride, (2). contacting the alkenyl succinic anhydride with chlorine or bromine in the absence of hydroxylic and solvent compounds to form halogenated alkenyl succinic anhydride, (3). contacting the halogenated alkenyl succinic anhydride with alkylene polyamine to form crude reaction product of halogenated alkenyl succinic anhydride and alkylene polyamine and (4). preferably contacting the crude reaction product with a strong inorganic base and recovering the purified reaction product. Lubricant compositions containing a detergent-dispersant quantity of said halogenated succinic anhydride-alkylene polyamine reaction product.
