Abstract
A composition of matter useful in lubricating oil for reducing friction in an internal combustion engine, said complex comprising the reaction product of alkoxylated amine, trithiocyanuric acid and adenine and having the formula: ##STR1## where R is a hydrocarbyl group of 2 to 22 carbon atoms, R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 20 carbon atoms, x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20, and a, b and c are independent numbers from 1.0 to 3.0 wherein the ratios between a:b, a:c and b:c range from 1.0:3.0 to 3.0:1.0.

A composition of matter comprising a complex which is the reaction product of alkoxylated amine, trithiocyanuric acid and adenine, said complex having the formula ##STR5## where R is a hydrocarbyl group of 2 to 22 carbon atoms, R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 20 carbon atoms, x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20, and a, b and c are independent numbers from 1.0 to 3.0 wherein the ratios between a:b, a:c arid b:c range from 1.0:3.0 to 3.0:1.0.
A lubricant oil composition comprising
- (a) a major amount of a lubricating oil basestock, and
- (b) a minor amount of a complex comprising the reaction product of alkoxylated amine, trithiocyanuric acid and adenine, said complex having the formula ##STR6## where R is a hydrocarbyl group of 2 to 22 carbon atoms, R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 20 carbon atoms, x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20, and a, b and c are independent numbers from 1.0 to 3.0 wherein the ratios between a:b, a:c and b:c range from 1.0:3.0 to 3.0:1.0.
