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.
摘要:
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.

摘要:
Reaction products in which polyethers are grown from substituted phenol-containing mannich bases have been found to be effective ashless dispersants and detergents for fuels and lubricants.
摘要:
Reaction products in which polyethers are connected to hydroxyalkylated polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for various lubricants and fuels.
摘要:
Reaction products which provide antioxidant properties to lubricants and fuels while serving as effective dispersants and detergents in these mediums. These products, of the reaction of a hydroxyalkylene substituted polyamines and substituted succinic anhydrides, contain mixtures of esters, amides and imides. Furthermore, preferred embodiments of the reaction products have pendent alcohol groups which provide extra dispersancy and detergency over traditional dispersants which typically do not have alcohol groups.
