摘要:
The invention herein is concerned with novel compositions of matter made by reacting phosphorus pentasulfide with a polyhydroxyester and then followed by reaction with a salt-forming metal-containing compound and lubricant compositions containing same.
摘要:
Zwitterionic Quaternary ammonium sulfates, and sulfonates are provided as new compounds and as highly effective additives to lubricants and liquid fuels. They have a variety of desirable effects, among them being their ability to reduce friction in an internal combustion engine, thereby reducing the amount of fuel consumed.
摘要:
The invention provides a compound effective as a friction reducer in lubricants and fuels, thus reducing the consumption of fuel. The compound is a boron derivative of a mixture of alkoxylated alcohols and hydroxysulfides.
摘要:
Certain borated additive compounds, such as borated mixed ethoxylated amines and ethoxylated amides or hydroxyalkyl imidazolines and hydroxyesters or hydrolyzed hydroxyalkyl imidazolines and ethoxylated amides and combinations thereof, provide highly effective multifunctional characteristics for various lubricating media into which they are incorporated.
摘要:
Boric acid salts and borate esters of hydroxyethyl alkyl imidazolines are effective friction reducing additives when incorporated into lubricating compositions.
摘要:
The invention herein is concerned with novel compositions of matter made by (1) reacting phosphorus pentasulfide with a polyhydroxyester and (2) reacting this product with a nitrogen-containing compound, and lubricant compositions containing same.
