Abstract

Compositions useful as additives for fuels and lubricants can be made by reacting (A) an aromatic compound having an OH or SH group attached to an aromatic nucleus and an aromatic hydrogen atom (e.g., a substituted phenol wherein the substituent is an alkyl group of at least 50 carbon atoms); (B) an aldehyde or reactive equivalent thereof (e.g., formaldehyde); (C) a non-amino hydrogen, active hydrogen compound (e.g., a phenol, N,N-dimethyl aniline, etc.) and optionally, (D) an aliphatic alkylating agent of at least 30 carbon atoms (e.g., a polyisobutene of about 50 carbon atoms).
