SUCCINIMIDES AND THEIR USE AS FUEL ADDITIVES Succinimides useful as detergents in fuels are prepared by reacting (a) at least one substituted succinic acid or acid derivative thereof containing an average of from 16 to 50 carbon atoms in the molecule and having an acyclic aliphatic substituent group containing an average of at least 12 but less than 30 carbon atoms, with (b) at least one alkanol polyamine containing an average of at least 4 carbon atoms and containing at least one primary amino group. When used as fuel additives, the succinimides are effective in reducing deposits in carburetors and injectors.
