Abstract
Abstract Fluid compositions containing a lubricant or liquid hydrocarbon fuel and a minor amount of a complex salt containing a 5- or 6-member ring are provided. These derivatives are made by complexing (1) the reaction product of an alcohol or an aminoalcohol with a succinic compound containing a long-chain hydrocarbon with (2) a metal salt. One such complex is one made by reacting a metal salt with the product of reaction between an alkylsuccinic acid or anhydride and said alcohol or aminoalcohol.
