Abstract
1-[di(4-octylphenyl)aminomethyl]tolutriazole is prepared in a mineral oil and blended with a liquid alkylated diphenylamine. The liquid product shows increased storage stability with respect to crystallization of the 1-[di(4-octylphenyl)aminomethyl]tolutriazole when the amine is added. This blend product can be stored for a prolonged period of time, and then utilized in a lubricant composition as an antioxidant and corrosion inhibitor.
