Abstract (en)
Benzophenone tetracarboxylic dianhydride, and esters or mixtures thereof when reacted with various hydrocarbyl amines provide automotive fuel additives for liquid hydrocarbon fuels, and such additives are highly useful as fuel detergents, intake valve and exhaust gas valve deposit reducers and as agents for preventing undesired deposits in the carburetor of an internal combustion engine in which liquid hydrocarbon fuels are normally susceptible to forming such deposits.
