Abstract
1-[Di(4-octylphenyl)aminomethyl]tolutriazole is prepared in a mineral oil wherein the reaction also contains between 0.1 and 5% by weight of a polyacrylate polymer dissolved in a mineral oil. The liquid product shows increased storage stability with respect to crystallization of the 1-[di(4-octylphenyl)aminomethyl]tolutriazole when the polyacrylate polymer is added during the reaction to prepare the 1-[Di(4-octylphenyl)aminomethyl]tolutriazole. This product can be utilized in a lubricant composition as an antioxidant and corrosion inhibitor.
