Abstract:
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.

Abstract:
A motor fuel composition which inhibits engine ORI and resists engine deposit formation comprises a mixture of hydrocarbons boiling in the range of 90.degree. F.-450.degree. F. and the reaction product of a dibasic acid anhydride, a polyoxyalkylene diamine, and a heterocyclic azole.
Abstract:
An additive composition for use in Diesel fuel to be combusted in a Diesel engine, the composition comprising, in admixture form:(a) about 6.0 weight percent di-tertiary butyl peroxide,(b) about 1.0 weight percent tall oil fatty imidazoline,(c) about 0.5 weight percent neo decanoic acid,(d) the balance being a hydrocarbon solvent carrier thoroughly mixed with the peroxide, imidazoline, and acid.
Abstract:
A process for the preparation of a natural liquid fuel and, more particularly, a process that allows a high sulfur natural fuel to be converted into energy by combustion with a substantial reduction in sulfur oxide emissions.
Abstract:
Hydroxylalkyl hydrocarbyl imidazoline-acyl sarcosine reaction products exhibit good friction reducing and antirust properties when formulated into a variety of lubricants and fuels at low concentrations.
Abstract:
Alcohols may be inhibited against corrosion by addition there to of an amide reaction product of (i) ##STR1## (preferably in the form of the acid, acid chloride or ester) and (ii) an amino tetrazole.
Abstract:
The reduction of octane requirement in a spark-ignited, internal combustion engine is achieved by introducing, with the combustion intake charge, a fuel and/or lubricant composition containing an octane requirement reduction amount of a substituted urea compound represented by the formula: ##STR1## in which X is an oxygen or sulfur atom, R.sub.1 and R.sub.3 are hydrocarbyl radicals having from 1 to 3 carbon atoms, and R.sub.2 is selected from the group consisting of ##STR2## Particularly useful as ORR agents are: (a) 4-[N-(2,4-xylyl) carbamoyl] morpholine;(b) 1-[N-(2,4-xylyl) carbamoyl] piperidine; and(c) 1-(2-pyridyl)-3-(3,4-xylyl)-2-thiourea.
Abstract:
The oxidation of a lubricating oil caused by metal components can be suppressed effectively by adding to the lubricating oil a compound represented by the formula ##STR1##
Abstract:
Novel zinc N,N'-alkenylsuccinoyl dipyridyl succinate is prepared by the novel reaction between an alkenylsuccinic anhydride, pyridine and zinc catalyzed by zinc chloride in pyridine reaction solvent. The novel zinc salt is useful to inhibit oxidation of hydrocarbon distillates and lubricant oils.
