摘要： Certain citric esters and amides, and certain mixtures thereof, e.g., mixtures comprising citrate oligomers, exhibit excellent anti-wear activity in lubricants. Many of these compounds or mixtures of compounds also exhibit a high degree of anti-wear synergy in combination with zinc dihydrocarbyldithiophosphates. The compounds of the invention are thus valuable tools that can allow one to reduce the amounts of zinc, and phosphates, that are used in the lubricant without sacrificing anti-wear performance.

摘要： Diaryl amines are selectively alkylated by reaction with branched olefins, which olefins are capable of forming tertiary carbonium ions and can be conveniently prepared from readily available branched alcohols. The diaryl amine products are effective antioxidants and often comprise a high amount of di-alkylated diaryl amines and a low amount of tri- and tetra-alkylated diaryl amines.

摘要： Certain alkylated 3-hydroxyphenylamine antioxidants wherein one phenyl is substituted by at least one hydroxyl group at the 3-position relative to the amine and the other phenyl is substituted by at least one substituent having 4 or more carbon atoms are surprisingly effective antioxidants, especially in lubricating oils.

摘要： Co-distilling a mixture of para-phenylene diisocyanate (PPDI) and solvent, collecting the mixture of solvent and PPDI as a solution, reacting this solution with a polyol to form a prepolymer, and then removing unreacted PPDI by distillation in the presence of one or more solvents provides lower color prepolymer and higher quality polyurethane resin than a similar process that omits the co-distillation of PPDI and solvent prior to reaction with the polyol.

摘要： Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines.

摘要： Blocked isocyanate terminated prepolymers with improved handling and processing properties are prepared from isocyanate terminated prepolymers with very low free isocyanate monomer content. The blocked prepolymers have lower melting points and/or viscosities compared to similar blocked isocyanate terminated having traditional, higher amounts of free isocyanate monomer. Curing compositions comprising the blocked prepolymers are prepared and cured to form polyurethane polymers with excellent properties.
