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