Triazole-organodithiophosphate reaction product additives for functional fluids

Abstract

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: ##STR1## wherein R.sub.7 is hydrogen or a C.sub.1 -C.sub.20 alkyl residue; R.sub.8 and R.sub.9 are the same or different and each is C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 alkenyl, C.sub.5 -C.sub.12 cycloalkyl, C.sub.7 -C.sub.13 aralkyl, C.sub.6 -C.sub.10 aryl or R.sub.8 and R.sub.9, together with the nitrogen atom to which they are attached, form a 5-, 6- or 7-membered heterocyclic residue or R.sub.8 and R.sub.9 is each a residue of formula: R.sub.12 X[(alkylene)O].sub.n (alkylene)-- II wherein X is O, S or N(R.sub.12), R.sub.12 is hydrogen or C.sub.1 -C.sub.20 alkyl, "alkylene" is a C.sub.1 -C.sub.12 alkylene residue and n is 0 or an integer from 1 to 6; R.sub.10 is hydrogen, C.sub.1 -C.sub.20 alkyl or C.sub.6 -C.sub.10 aryl or C.sub.7 -C.sub.18 alkyl phenyl; and R.sub.11 is hydrogen, C.sub.1 -C.sub.20 alkyl or a residue --CH.sub.2 NR.sub.8 R.sub.9 wherein R.sub.8 and R.sub.9 have their previous significance; with (B) an organodithiophosphate having the formula: ##STR2## in which R.sub.13 is a C.sub.1 -C.sub.20 alkyl or C.sub.7 -C.sub.18 alkyl phenyl or C.sub.7 -C.sub.13 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.
