The present disclosure generally relates to alkylated aromatic compounds useful as basestocks and additives for high viscosity applications. In an embodiment is provided an alkylated aromatic compound. In another embodiment is provided a lubricant formulation that includes an alkylated aromatic compound. In another embodiment is provided a lubricant formulation that includes an alkylated aromatic compound, an additive, and optionally, a Group III basestock, Group IV basestock, Group V basestock, or a combination thereof, the Group V basestock being different than the alkylated aromatic compound. In another embodiment is provided a method of forming a lubricant formulation that includes introducing a mPAO, an aromatic compound, and an acid catalyst to a reactor under reactor conditions to form an alkylated aromatic compound; and introducing the alkylated aromatic compound to an additive to form a lubricant formulation.
Dihydroxyaryl-hydroxyaliphatic borates have been found to be effective antioxidant additives when incorporated into various lubricating media.
Sulfurized phenols, e.g., phenol sulfides, disulfides or polysulfides, oligomers thereof or mixtures of same when treated with alkyl vinyl ethers provide excellent metal anti-corrosivity characteristics without significant reduction of antioxidant, antiwear or other desired properties when incorporated into organic media such as lubricants.
Ethylene terpolymers with a low number average molecular weight of from 1500 to 5500 and a vinyl acetate content of from 10 to 20% by weight, useful in wax modifiers or petroleum fraction additives, are prepared by high pressure polymerization (at least 500 bar and 150°C) in presence of 10 to 25% by weight of an iso olefin such as isobutylene. Incorporation of the iso olefin gives terpolymer products containing from 3 to 13% weight of iso olefin.
A synthetic lubricating composition is provided comprising a major proportion of a base oil and a minor proportion of a plurality of additives, added for the purpose of substantially improving properties of such composition other than viscosity index. The base oil comprises (1) a mixture of at least two fatty acid esters of specified characteristics with regard to viscosity and (2) a hydrogenated oligomer of an alpha olefin of 6 to 12 carbon atoms. The resulting blend of base oil and additives has a viscosity index which differs from that of the base oil by no more than 20.
Improvements introduced in the preparation of lubricating compositions comprising a significant amount of mineral lubricating oil, approximately 3 to 12 weight percent of mixed calcium salts of acetic acid and C7 to C12 fatty acid in a molar ratio of said acetic acid to said fatty acid of 11.5: 1 to 25: 1 and about 0.1 to 10.0 weight percent of detergent additive of the lubricating oil capable of stabilizing said composition against separation in case of water contamination of said composition, being said detergent additive selected from the group consisting of alkali metal and alkaline earth metal soluble salts of alkyl phenol having from about 5 to 20 carbon atoms in each alkyl group and about 1 to 3 alkyl groups per phenol group, treated polymers by P2S5 of C2 to C5 olefins, said polymers having molecular weights in the range of approximately 500 to 200,000 Staudinger, and products of reaction of said salts of said alkyl phenols and said polymers.
Mixed phenol/dimercaptothiadiazole-derived hydroxythioether borates have been found to be effective antiwear/antioxidant multifunctional additives for lubricants.
