The present invention provides for the use of certain oil soluble iodides to enhance the oxidation resistance of lubricating oils and fuels, and for the novel formulated compositions containing these iodides. Oil soluble iodides such as C.sub.16 to C.sub.78 alkyl ammonium as well as oil solubilizable or dispersible iodides such as CoI.sub.2, CuI, KI and NaI in combination with a suitable dispersing agent may be used. Typically a minor amount of additive, from about 40 to about 1000 ppm is used. The additive is effective as an antioxidant in a variety of different types of base and formulated oils.

Oil soluble iodides as lubricant antioxidants

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.

Method of improving the thermal stability of quaternary ammonium

Disclosed is a process for converting solid carbonaceous material, such as coal and oil-shale, to a discriminate range of liquid and gaseous products, which process comprises treating the carbonaceous material with a hydrogen-containing gas at short gas and long solids residence times in two or more temperature zones.
