New N-substituted compounds, useful as metal deactivators in functional fluids, have the formula I: <IMAGE> I in which R1 and R2 are the same or different and each is C-C20 alkyl, C3-C20 alkenyl, C5-C12 cycloalkyl, C7-C13 aralkyl, C6-C10 aryl, or R1 and R2, together with the nitrogen atom to which they are each attached form a 5-, 6- or 7-membered heterocyclic residue, or R1 and R2 is each a residue of formula II: R3X[(alkylene)O]n(alkylene)-II in which X is O, S or N, R3 is hydrogen or C1-C20 alkyl, alkylene is a C1-C12 alkylene residue and n is 0 or an integer from 1 to 6, or R1 has its previous significance and R2 is a residue of formula III: <IMAGE> III or R2 is a residue of formula III as defined above R1 is a residue of formula IV: -[alkylene]n-N(R4)-A-[N(R4)2]m IV wherein m is zero or 1 and, when m is zero, A is a residue of formula III and, when m is 1, A is alkylene or C6-C10- arylene and alkylene and n have their previous significance and R4 is a residue of formula III, as hereinbefore defined. |
