摘要:
Triazole compounds are grafted onto alkyl or alkenyl succinimides by using diisocyanates to effect the coupling. The process is carried out by first reacting a 1,2,3 -triazole with a diisocyanate to produce a triazole substituted urea addition product containing a single unreacted isocyanato group. This intermediate reaction product is then reacted with an alkyl or alkenyl succinimide ashless dispersant prepared from an alkyl or alkenyl succinic acid or anhydride and a polyamine by known methods. The novel composition so produced comprises a multifunctional hydrocarbon fuel or lubricant additive.

This invention is directed to a lubricant composition that is comprised of a continuous phase and a discontinuous phase, i.e., a two phase lubricant composition. The continuous phase and the discontinuous phase of the lubricant of this invention are oil or oil type compositions that are essentially insoluble in one another. The lubricant composition is comprised of a continuous phase base oil that is comprised of a low viscosity Group II, III, IV or GTL base stock or a blend of at least two of the Group II, III, IV and GTL base stocks, optionally including a low viscosity Group V base stock, with the continuous phase base oil having, independently, a viscosity of from 1 to 100 cSt at 100° C. The lubricant composition is further comprised of a discontinuous phase that is comprised of an ester composition having a mean average droplet size of from 0.01 microns to 20 microns, in which the ester composition is comprised of an ester compound having no ether linkages.

Reaction products, in which aromatic acid bis(polyether ester) is added to succinimides, are effective antioxidants, dispersants, and detergents for fuels and lubricants.
摘要:
A lubricant or fuel composition contains a major portion of a lubricant or fuel and a minor portion of an additive composition which is the reaction product of long chain epoxides and polyamines such as polyethyleneamines.
摘要:
Disclosed is an additive for lubricant or fuel compositions comprising the boronated reaction product of polyalkenyl-substituted succinimides, aldehydes and triazoles.
摘要:
Disclosed is an additive for liquid hydrocarbon fuel composition, particularly diesel fuels. The additive composition is the reaction product of polyalkenyl-substituted succinimides, aldehydes, and triazoles. It also finds use in lubricant compositions.
