摘要:
A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.
摘要:
The invention provides a composition comprising a mixture of tridecanols wherein at least about 60 wt % of the mixture is linear tridecanol and at least about 10 wt % of the mixture is branched tridecanols wherein the branched tridecanols have branching on the second carbon atom. The mixture of tridecanols may be converted to one or more derivatives, and these derivatives may be used in laundry detergents, cleaning products or as an agricultural adjuvant, an emulsifying agent, a lubricant additive, a pour point depressant, or a personal care ingredient.

摘要:
This disclosure is directed to a method of forming an additive package for a lubricant composition. The method includes the step of providing a base oil and a dispersant, the step of heating the base oil and the dispersant, and the step of combining the base oil and the dispersant to form a first mixture. The method further includes the step of providing a detergent, the step of heating the detergent, and the step of combining the first mixture and the detergent to form a second mixture. The method further includes the step of providing an anti-wear additive and a seal compatibility additive, the step of heating the anti-wear additive the seal compatibility additive, and the step of combining the second mixture, the anti-wear additive, and the seal compatibility additive to form the additive package.

摘要:
Disclosed are compositions of a major amount of alkylated aromatics compounds, in particular alkylated naphthalene and alkylated benzene, optionally combined with API Group II, Group III, Group IV and/or ethylene copolymers, showing improved thermo-oxidation performance when containing an additive combination including an alkylated or non-alkylated diarylamine and a sulfur-containing metal passivator. Particularly, the lubricating compositions include at least 55 wt % of a base oil selected from the group consisting of alkylated naphthalene, alkylated benzene and combinations thereof, and from 0 wt % to 45 wt % of another base oil component. The ratio of amine component to sulfur component in the additive combination is from 1:1 to 20:1. The compositions contain an amount of base oil other than alkylated naphthalene, alkylated benzene and API Group II, Group III, Group IV and/or ethylene copolymers of less than 10 wt % based on the total weight of the components comprising the lubricating composition.
摘要:
Compositions comprise first antioxidants and first additives, such as, a surface additives, performance enhancing additives and lubricant protective additives and optionally second additives and/or second antioxidants. The compositions are useful to improve lubricants, lubricant oils and other lubricant materials. The compositions and methods generally provide longer shelf lives, increased oxidative resistance, improved quality and/or enhanced performance to lubricants or lubricant oils.
摘要:
