摘要:
Tetra-alkylated phenylenediamine compounds useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials and meet copper corrosion requirements, and lubricating oil compositions containing such phenylenediamine compounds.
摘要:
Provided is a composition comprising fatty acid bis-amide, inorganic particulate such as pumice, cellulosic particulate, thermoplastic and maleic anhydride grafted polyolefin. The combination of an ethylene bis-amide and a minor amount of pumice produces cellulosic-thermoplastic composite that has superior extrusion properties over conventional metal stearate/ethylene bis-stearamide (EBS) compositions such as improved flex strength and resistance to water absorption.
摘要:
Fuels, especially hydrocarbon fuels, and lubricants, especially lubricating oils, contain dithiocarbamyl β-hydroxy fatty acid esters, a class of anti-corrosion, anti-wear, anti-fatigue, and extreme pressure additives that are derived from epoxidized fatty acid esters. The additives exhibit synergistic anti-wear activity in combination with phosphorus containing additives.
摘要:
Fuels, especially hydrocarbon fuels, and lubricants, especially lubricating oils, contain a class of anti-corrosion, anti-wear, anti-fatigue, and extreme pressure additives that are derived from 1,3-dithiolane-2-thiones.

摘要:
A composition comprising: (A) a lubricant, and (B) at least one alcohol that is the reaction product of mercaptobenzothiazoles, mercaptothiazolines, or mercaptobenzimidazoles with various epoxies.
摘要:
Disclosed herein is a composition comprising: (A) a lubricant, and (B) at least one imidazole thione compound of the formula: wherein R1, R2, R3, and R4 are independently selected from the group consisting of alkyl, functionalized alkyl, and hydrogen.
摘要:
An alkylated 1,3-benzenediamine compound used as a deposit-control lubricant additives for organic materials including lubricating oil, gasoline, and diesel fuels. The invention improves the oxidative stability of the lubricants and fuels by adding the alkylated 1,3-benzenediamine compound. The alkylated 1,3-benzenediamine compound is formed using a catalytic hydrogenation that alkylates the 4 and/or 6 position of the central aromatic ring.
