The invention also provides a method of lubricating an internal combustion engine using such a lubricating composition.

The lubricating oil composition of the present invention contains a base oil, a 2,6-di-tert-butylphenol (A), and at least one compound (B) selected from a benzotriazole compound and a sorbitan compound.

Zinc complex greases with different complexing acids having dropping points comparable to lithium greases and tailor-made dropping points can be made by processing at low temperature in open as well as close kettle process. The present invention discloses a process of manufacturing Zinc complex greasesthrough reaction of fatty acid and complexing acid with zinc oxide in mineral oil to obtain zinc complex greases having high dropping points of 180 to 280 C.

Stable, solid triamine compositions are disclosed. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating. Beneficially, the solid triamine compositions are at least partially neutralized, allowing activity of 90% and greater of the biocidal triamine, and provide at least substantially similar or superior performance and micro efficacy to liquid formulations.

The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.

The present disclosure relates to viscosity index modifiers that have dispersant properties and lubricating oil compositions comprising said viscosity index modifiers. The viscosity index modifier is the reaction product of an acylated olefin copolymer, a polyamine, and a dicarboxylic acid or anhydride thereof that can react with a free primary amine of the polyamine to form a ring moiety. The disclosure also relates to the use of lubricant compositions comprising the viscosity index improvers of the disclosure for improving the soot or sludge handling characteristics of an engine lubricant composition, while minimizing the deterioration of engine seals.

A sulfur- and phosphorus-free extreme pressure lubricant and a preparation method thereof is disclosed. The lubricant is prepared by using Turkey red oil, a cyclic anhydride compound, triethanolamine, nano polytetrafluoroethylene powder, an alcohol compound, and water as raw materials. The lubricant does not contain hazardous substances such as sulfur and phosphorus. This reduces the harm to the environment, equipment, and human body, and conforms to the development trend of modern industrial production. Moreover, the lubricant has excellent extreme pressure performance, and can effectively reduce the downhole friction and torque, thereby meeting the construction requirements of extended reach wells and horizontal wells.

Provided is a lubricant composition for plastic working which lubricant composition is excellent in lubricity and mold releasability. The lubricant composition for plastic working which lubricant composition contains: (a) silica; and (b) an alkali metal salt of an organic acid, a weight ratio of (b) the alkali metal salt of the organic acid to (a) the silica (a weight of (b)/a weight of (a)) being not less than 2, is used.
