20080220999 | NOVEL MOLYBDENUM COMPOUNDS - Novel molybdenum compounds are prepared by reacting a hindered amine with a molybdenum source, in the presence of one of (a) water, (b) a diol and water, and (c) the reaction product of a fatty oil and a multifunctional amine, and water. Lubricant compositions containing these new compounds are more stabilized against oxidation and have improved friction reducing properties. Synergy is observed when the novel compounds are combined with a diaryl amine in a lubricant composition. | 09-11-2008 |

20120264666 | MOLYBDENUM DIALKYLDITHIOCARBAMATE COMPOSITIONS AND LUBRICATING COMPOSITIONS CONTAINING THE SAME - A novel molybdenum dithiocarbamate composition is produced by preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene, and preparing a molybdenum dithiocarbamate composition from the DTDA intermediate. The resulting molybdenum dithiocarbamate composition are according to formula (1), wherein R | 10-18-2012 |
20130123156 | LUBRICANT COMPOSITION - 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 | 05-16-2013 |
20140213493 | ASHLESS LUBRICANT COMPOSITION - A lubricant composition with improved antioxidant capability is provided by way of an additive composition containing a metal free sulfur-containing compound, an aromatic amine, and a hindered amine. Particularly effective metal-free sulfur-containing compounds include ashless dithiocarbamates, such as methylenebis(dibutyldithiocarbamate), and sulfurized fatty acids. | 07-31-2014 |
20140342957 | METHOD FOR REDUCING CRYSTALLIZATION OF 1-[DI(4-OCTYLPHENYL)AMINOMETHYL]TOLUTRIAZOLE - 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 | 11-20-2014 |
20150087568 | ASHLESS LUBRICANT COMPOSITION - A lubricant composition with improved antioxidant capability is provided by way of an additive composition containing a metal free sulfur-containing compound, an aromatic amine, and a hindered amine.
