摘要:
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;reacting olefinic C.sub.20 + polyalpha-olefin oligomers having a branch ratio of less than 0.19 and phosphite ester in a mixture with peroxide catalyst at elevated temperature whereby phosphite ester adduct of said polyalpha-olefin is formed;separating said reaction mixture products and recovering said adduct.

摘要:
Polyalkylene amine coupled heterocyclic compounds are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as anti-wear, friction-modifying, thermal and oxidative stabilizing properties. The beneficial effects of the product of the instant invention apparently result from an internal synergism between the polyalkylene amine groups and the heterocyclic groups.
摘要:
The invention relates to lubricant and fuel additives having antiwear and friction reducing properties. The invention also relates to compositions of oils with viscosities appropriate for lubricants, greases produced therefrom, and fuels and methods for making these compositions. Described in this invention are products of nitrogen heterocycles, such as benzotriazole and tolyltriazole, with amines, such as alkyl amines, aliphatic diamines, alicyclic amines, heterocyclic amines, propylene amines, and aliphatic etheramines, that are linked using carbonyl compounds (e.g., aldehyde, ketone or glyoxal). Additionally, products generated by the reaction of carboxylic acids or carboxylic acid generating compounds (e.g., salts or esters) with carbonyl (e.g., aldehyde, ketone or glyoxal) coupled nitrogen heterocycles and amines, including those described above, are also included in this invention. These products can be used in fuels and lubricants to produce improved antiwear and friction reducing properties.
