  • Method for reducing crystallization of 1-[di(4-octylphenyl)aminomethyl]tolutriazole
    Patent number: 9546339
    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.
    Type: Grant

  • Lubricant composition
    Patent number: 8889606
    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.
