Abstract:
The invention relates to novel compositions comprising ene and free radical adducts of unsaturated and saturated hydrocarbons, and acyclic and cyclic vicinal polycarbonyl compounds such as diethyl ketomalonate and indantrione. The adducts are reacted with nucleophiles such as amines, electrophiles such as anhydrides and esters, and metal ions. Post-products are obtained via reaction of said products with capping reagents such as boric acid. Compositions containing said adducts, products and post-products include oleaginous substances such as fuels and lube oils.
Abstract:
The presence of a minor amount of an anti-oxidant, a metal detergent, a dispersant or mixtures thereof in a hydrocarbon liquid containing certain quaternary ammonium hydroxides has been found to be effective in improving the thermal stability of the hydroxides.
Abstract:
A lubricant or fuel composition contains a multifunctional antioxidant and antiwear amount of an O,O-diorgano-S-(2-hydroxyalkyl) phosphorodithioate derived hydrogen phosphonate which can be made by reacting a diorganophosphorodithioic acid with an epoxide and a dialkyl phosphite, such as dimethyl phosphite.
Abstract:
According to the present invention, oleaginous compositions having improved stability are provided, wherein high molecular weight ashless dispersants and metal detergents are pre-blended at a temperature of at least 100.degree. C. for a period of from 1 to 10 hours, cooled to at least 85.degree. C. and admixed with additional additives, including oil soluble copper antioxidants and zinc dialkyl dithiophosphate antiwear agents.

Abstract:
A fuel composition for internal combustion engines, and more particularly, a fuel composition for internal combustion engines containing less than about 0.5 gram of lead per gallon of fuel is described. The fuel provides acceptable valve seat protection in engines designed to operate on leaded fuels. A further aspect of the invention is to reduce deposit formation within the cylinders.
Abstract:
Highly effective antioxidants that are particularly useful in crankcase lubricating oil formulations of relatively low ash content are prepared by the condensation of phosphorodithioates of alkyl phenol sulfides with compounds having activated double bonds, particularly with styrene, alkyl styrenes, highly reactive olefins, vinyl esters and acrylate esters.
Abstract:
A gasoline additive and method for making such additive wherein bituminous coal is successively immersed into a mixture of (1) mineral spirits and carbide, (2) a ketone and carbide, and (3) benzene and carbide, for a period of from about 10 to 30 hours in each mixture. The mixtures are then combined and to 100 parts by volume thereof are added, by volume, 60 parts methyl isobutyl ketone, 300 parts orthodichlorbenzene, 370 parts mineral spirits and 75 parts tri-o-cresyl phosphate. When this final mixture is added to gasoline in an amount of about one ounce per ten gallons of gasoline, automotive vehicles - operating on such gasoline have their mileage per gallon of gasoline improved up to about thirty to forty percent and more.

Abstract:
A method of reducing manganese containing deposits formed on the surfaces of jet engines from burning fuel containing organomanganese compounds as a smoke reducer is described. The deposits are reduced by adding an organic molybdenum compound to the organomanganese containing fuel. Cyclopentadienyl manganese tricarbonyl compounds are useful organomanganese compounds; molybdenum naphthenate is a useful molybdenum compound.
