Cyclic diol- and diol-ester phosphite adducts of olefins and polymeric olefins provide superior multifunctional and lubricating fluid media with internal synergistic multifunctional antiwear, antioxidant properties and extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as liquid hydrocarbon fuels.

Diol phosphite adducts of olefins as multifunctional lubricants and

Sulfur derivatives of unsaturated oligomers formed from alpha-olefins of 2 to 20 carbon atoms which oligomer has a branch ratio of less than 0.19.

Sulfide adducts of high viscosity index polyalphaolefins

It has now been discovered that oligomers of C.sub.6 - C.sub.20 alpha-olefins, such as 1-decene, with branch ratios below 0.19 and high viscosity indices (HVI) can be functionalized to provide unique phosphite derivatives. Functionalized polyalpha-olefin lubricants compositions are prepared with superior properties by adding functionalized organophosphites to the olefinic bond of HVI-PAO. The invention encompasses a process for the preparation of lubricant range hydrocarbons containing phosphonate functional groups, comprising;

Phosphonate adducts of olefinic lubricants having enhanced properties

Novel phosphite derivatives of propylene based lube olefins are novel lubricating fluid media with internal synergistic multifunctional extreme pressure, antiwear and antioxidant properties. These compounds exhibit the same multifunctional characteristics when used in minor additive amounts in either mineral or synthetic lubricating oils as well as fuels.

Phosphite derived propylene based multifunctional lubricants and

Sulfurized propylene based lube olefin derivatives are superior lubricating fluids with internal synergistic multifunctional extreme pressure/antiwear and antioxidant properties as well as multifunctional extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as fuels.

Organosulfur adducts as multifunctional additives for lubricating oils

Hydrocarbyl thiophosphoric acid-phosphite derived olefin and polymeric olefin adducts are superior as lubricating fluid media with internal synergistic multifunctional antiwear, antioxidant properties, and as multifunctional extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as fuels.

Multifunctional lubricants and multifunctional additives for lubricants

Aminic orthoester derivatives of the formulae ##STR1## are effective in stabilizing organic materials against oxidative, thermal and actinic degradation.

Arylsubstituted amidines

An improved process for preparing dithiobisphenols wherein the appropriate phenol is reacted with sulfur monochloride in the presence of substantially molar amounts of an aliphatic or heterocyclic amine.
