Monoalkylated diphenyl oxides are high-temperature stable lubricant fluids having excellent low temperature viscometrics, and excellent additive solubility. These monoalkylated products are obtained by the alkylation of diphenyl oxide using, for example, an olefin alkylating agent, usually in the C.sub.8 to C.sub.18 range, in the presence of an acidic zeolite alkylation catalyst such as USY, which provides the selectivity for the monoalkylated product.

Alkylated diphenyl ether lubricants

Alkoxylated- or polyalkoxylate-amine-phosphite derived olefin adducts are superior as lubricating fluid media and as multifunctional additives with internal synergistic antioxidant and extreme pressure/antiwear properties for both mineral and synthetic lubricating oils as well as fuels.

Monoalkylated phenoxathins are high-temperature stable lubricant fluids having extreme pressure and antiwear properties, additive solubility and inherent EP/antiwear properties. These novel phenoxathin fluids may also be used as additives in other lubricant fluids and are prepared by alkyating a phenoxathin in the presence of an acidic zeolite catalyst.

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;
