    摘要: Described are multi-ring antioxidant products comprising at least one sulfur-bridged aromatic hydrocarbon compound substituted on at least one of its aromatic rings by at least one sterically hindered 3,5-dihydrocarbyl-4-hydroxybenzyl moiety. Such products have the formula: R—Sn—R[—S—R]m wherein each R is, independently, an aromatic hydrocarbon group having 6-12 carbon atoms, wherein m is 0-20, wherein n is 1-6 when m is 0, and when n is 1, m is 1-20; and wherein at least one of R, R1, and R2 is substituted by at least one such sterically hindered moiety. The preparation of such products and their use as antioxidants in compositions normally susceptible to oxidative degradation in oxygen or air, e.g., liquid fuel and lubricants, are also described.

    摘要: A premium synthetic lubricant having antiwear properties comprises a synthetic isoparaffinic hydrocarbon base stock and an effective amount of at least one antiwear additive. The antiwear additive is preferably at least one of a metal phosphate, a metal dialkyldithiophosphate, a metal dithiophosphate a metal thiocarbamate, a metal dithiocarbamate, an ethoxylated amine dialkyldithiophosphate and an ethoxylated amine dithiobenzoate. Metal dialkyldithiophosphates are preferred, particularly zincdialkyldithiophosphate (ZDDP). The base stock is derived from a waxy, Fischer-Tropsch synthesized hydrocarbon feed fraction comprising hydrocarbons having an initial boiling point in the range of about 650-750.degree. F., by a process which comprises hydroisomerizing the feed and dewaxing the isomerate. The lubricant may also contain hydrocarbonaceous and synthetic base stock material in admxture with the Fischer-Tropsch derived base stock.
