Abstract:
Additives which improve the low-temperature properties of distillate fuels are the oligomeric/polymeric reaction products of one or more bicyclic or alkyl anhydrides or their diacid equivalents and one or more long-chain epoxides or their corresponding acid/diol equivalents, with optional termonomers.
Abstract:
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.
Abstract:
Sulfurized olefins, particularly sulfurized isobutylene, are reacted with glycerol monooleate. The resulting product is useful as an additive for lube oil compositions.
Abstract:
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.
Abstract:
A fuel composition contains an antiwear additive comprising the reaction product of heterocyclic compound having antiwear activity such as a triazole e.g. benzotriazole, tolyltriazole, and a copolymer with succinic anhydride moiety, such as an olefin/maleic anhydride copolymer.
Abstract:
Products of reaction between 1-alkyl-N,N-dialkyl ethanolamines and copolymers of maleic anhydride are new additives which are effective in lowering the cloud point of distillate fuels.
Abstract:
Reaction products in which polyethers are connected to polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for various oils of lubricating viscosity.
Abstract:
Reaction products in which polyethers are connected to polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for fuel.
Abstract:
(2,6-Dimethyl-3-substituted phenyl)methyl cyclopropanecarboxylates and insecticidal compositions containing these esters are useful for the control of a broad range of insects and acarids.
