Abstract

Motor gasoline additives which inhibit the formation of deposits in carburetters consist of one or more tetrahydropyrinidines of formula <FORM:0903032/III/1> in which R is an aliphatic hydrocarbon radical containing 8 - 18 carbon atoms and R1 is a naphthenyl radical. The tetrahydropyridines are usually used in the form of mixtures and are added to motor gasoline in an amount of 1 -200 lbs. per thousand barrels. The gasoline may also contain small amounts of tetraethyl lead, phenylene diamine, N,N1-disalicylidene-1, 2-propamediamine, 2,6-di-tert-butyl-4-methyl phenol, cresyl diphenyl phosphate and glyceryl mono-oleate.ALSO:The invention comprises tetrahydropyrimidines of formula <FORM:0903032/IV (b)/1> in which R is an aliphatic hydrocarbon radical containing from 8 to 18 carbon atoms and R1 is a naphthenyl radical. They may be prepared by reacting at elevated temperature at least one naphthenic acid with at least one aliphatic hydrocarbon substituted propylenediamine of formula RNHCH2CH2CH2NH2, and removing the water as formed. Generally the tetrahydropyrimidines are obtained as mixtures from mixtures of diamines and mixtures of naphthenic acids.
