Compositions made by reacting (A) an acylated amino hydrocarbyl sulfonic acid having an acyl portion containing a substantially saturated hydrocarbyl substituent of at least about 12 carbon atoms and bonded to the amino hydrocarbyl sulfonic acid through an acyl, acylimidoyl or acyloxy linkage, (B) a

Compositions made by reacting (A) an acylated amino hydrocarbyl sulfonic acid having an acyl portion containing a substantially saturated hydrocarbyl substituent of at least about 12 carbon atoms and bonded to the amino hydrocarbyl sulfonic acid through an acyl, acylimidoyl or acyloxy linkage, (B) a heterocyclic reagent such as an epoxide, episulfide or aziridine and (C) an amino compound having about 1 to about 400 carbon atoms or an organo-sulfide having 2 to about 50 carbon atoms are useful in fuels and lubricants as dispersants, antistatic agents and corrosion inhibitors.
