Alkyl-guanidino-heterocyclic compounds, their manufacture and use as additives for fuels and lubricants

Abstract

Alkyl-guanidino heterocyclic compound produced by alkylation with a halogenated hydrocarbon of the general formula RX.sub.n, of a guanidino-heterocyclic compound (A) of general formula: ##STR1## in which R is substantially a hydrocarbon radical containing about 10 to 200 carbon atoms, X is a halogen atom and n is 1 or 2; Y is an oxygen atom, --O--, a sulfur atom --S--, a --NH-- group, or a --COHN-- group in which the carbon atom is directly bound to the benzene ring, R' and R" are each a hydrogen atom, an alkyl radical having from 1 to 10 carbon atoms, or a --Z--Ar group in which Z is a divalent atom or group and Ar is a substituted or unsubstituted aromatic radical, R' and R" being capable of forming together, when they are in ortho position, an aliphatic or aromatic cycle fused to the benzene ring.
