Reaction mixtures from reacting di- and triazines with sulfur-containing compounds and lubricants and fuels containing the same

A fuel or lubricant composition of matter comprising a major amount of a lubricating oil or normally liquid fuel and a minor, oxidation inhibiting amount of a composition of matter which is the reaction mixture made by reacting:

• (A) at least one of the substituted di- and triazine compounds of the formula ##STR35## wherein Q and Q' are each independently selected from the group consisting of halo, hydrocarbyloxy of the formula --OR and hydrocarbyl of the formula --R, wherein each R independently contains up to about 20 carbon atoms, with the proviso that at least one of Q and Q' is hydrocarbyloxy or halo;
• X and X' are each independently selected from the group consisting of oxygen, divalent sulfur, .dbd.NH, or .dbd.NR.sub.1 wherein R.sub.1 is as R above;
• and each R' is independently a hydrogen or a hydrocarbyl of up to about 10 carbon atoms;
• with
• (B) at least one mercapto compound or salt thereof of the formula
• ZSY
• wherein Y is selected from the group consisting of hydrogen, a Group I or an equivalent of a Group II metal cation or an ammonium cation having up to about 20 carbon atoms or mixtures of two or more of these and Z is selected from the group consisting of:
• (1) hydrocarbyl groups of the formula --R" having from 4 to about 40 carbon atoms;
• (2) phosphorus acid groups of the formula ##STR36## wherein each R is defined as in (A);
• each n is independently zero or 1;
• and each D is independently oxygen or divalent sulfur;
• (3) amido-carbo groups of the formula ##STR37## wherein each R and X are defined as in (A);
• (4) hydrocarbyloxycarbo groups and sulfur-containing analogs of the formula ##STR38## wherein R and D are defined as in (B) (2);
• and (5) mixtures of any two or more of any of the groups within (B) (1), (B) (2), (B) (3), and/or (B) (4);
• provided that when neither of Q and Q' is hydrocarbyloxy, then Y is a Group I or an equivalent of a Group II metal cation.

A process for making a nitrogen and sulfur-containing composition comprising the step of reacting

• (A) at least one of the substituted di-and triazine compounds of the formula ##STR39## wherein Q and Q' are each independently selected from the group consisting of halo, hydrocarbyloxy of the formula --OR and hydrocarbyl of the formula --R, wherein each R independently contains up to about 20 carbon atoms, with the proviso that at least one Q and Q' is hydrocarbyl or halo;
• X and X' are each independently selected from the group consisting of oxygen, divalent sulfur, .dbd.NH, or .dbd.NR.sub.1 wherein R.sub.1 is as R above;
• and each R.sup.1 is independently a hydrogen or a hydrocarbyl of up to about 10 carbon atoms;
• with
• (B) at least one mercapto compound or salt thereof of the formula
• ZSY
• wherein Y is selected from the group consisting of hydrogen, a Group I or an equivalent of a Group II metal cation, or an ammonium cation up to about 20 carbon atoms or mixtures of two or more of these and Z is selected from the group consisting of:

• (2) phosphorus acid groups of the formula ##STR40## wherein each R is defined as in (A);
• each n is independently zero or 1;
• and each D is independently oxygen or divalent sulfur;
• (3) amido-carbo groups of the formula ##STR41## wherein each R and X are defined as above in (A);
• (4) hydrocarbyloxycarbo groups and sulfur-containing analogs of the formula ##STR42## wherein R and D are defined as in (B) (2) above;
• and (5) mixtures of any two or more of any of the groups within (B) (1), (B) (2), (B) (3), and (B) (4);
• provided that when neither of Q and Q' is hydrocarbyloxy, then Y is a Group I or an equivalent of a Group II metal cation.
