New reaction products, useful as additives for functional fluids, are obtained by reacting, at elevated temperature, (A) a triazole having the formula IA or IB: <IMAGE> IA <IMAGE> IB wherein R7 is hydrogen or a C1-C20 alkyl residue; R8 and R9 are the same or different and each is C1-C20 alkyl, C3-C20 alkenyl, C5-C12 cycloalkyl, C7-C13 aralkyl, C6-C10 aryl or R8 and R9, together with the nitrogen atom to which they are attached, form a 5-, 6- or 7-membered heterocyclic residue or R8 and R9 is each a residue of formula: R12X[(alkylene)O]n(alkylene)-II wherein X is O, S or N(R12), R12 is hydrogen or C1-C20 alkyl, "alkylene" is a C1-C12 alkylene residue and n is 0 or an integer from 1 to 6; R10 is hydrogen, C1-C20 alkyl or C6-C10 aryl or C7-C18 alkyl phenyl; and R11 is hydrogen, C1-C20 alkyl or a residue -CH2NR8R9 wherein R8 and R9 have their previous significance; with (B) an organodithiophosphate having the formula: <IMAGE> III in which R13 is a C1-C20 alkyl or C7-C18 alkyl phenyl or C7-C13 aralkyl group, M is a metal ion of Group IA, IB, IIA, IIB, VB, VIB, VIIB or VIII of the Periodic System of Elements, and y is the valency of M. |
