摘要： An oil composition comprising a first component having pendant groups and a second component but free of a third component and process for making such oil composition, where a single molecule of the third component can form large shearable stable complex structure with two molecules of the first component via van der Waals force between pendant groups and the terminal carbon chains, and a single molecule of the second component is capable of adjoining no more than one molecule of the first type. The oil composition has high shear stability making it suitable for use in lubricants subject to repeated high shear stress events.

摘要： An oil composition comprising a first component having pendant groups, a second component having two or more terminal carbon chains, and optionally a third component, where a single molecule of the second component can form shearable stable structure with two molecules of the first component via van der Waals force between pendant groups and the terminal carbon chains. Shear stability of the oil can be improved if the total concentration of the heavy fraction of the shearable stable structure is controlled at a low concentration.

摘要： A PAO lubricant base stock having a KV100 of at least 200 cSt and comprising multiple PAO molecules comprising at least 200 carbon atoms per molecule, wherein each of the PAO molecules comprises multiple pendant groups; and the average pendant group length of all the pendant groups excluding one methyl on each of the PAO molecules among at least 90 mol % of all of the PAO molecules, if one or more methyl is present, is at least 6.0. The PAO base stock exhibits high EHL thicknesses at 40° C., 80° C., and 120° C., rendering it particularly useful in lubricant compositions experiencing high-stress events such as gear oils, automotive transmission oils, and the like.

摘要： Disclosed is a lubricant base stock blend comprising a PAO base stock and an alkylated aromatics (AA) base stock, wherein at least the longer portion of the pendant groups attached to the carbon backbones of the PAO molecules have comparable length to at least the longer portion of the side chain groups attached to the aromatic ring structure of the AA molecules. The comparable lengths of at least the longer portion of the pendant groups and the side chain groups lead to enhanced improvement in oxidation stability of the blend.

摘要： Alkylated naphthalene compositions are usually formed by reacting naphthalene with an electrophilic agent under acid-catalyzed conditions to afford a mixture of monoalkylated naphthalenes, dialkylated naphthalenes, and sometimes polyalkylated naphthalenes. Reaction conditions are usually chosen to change the product distribution for purposes of modifying lubricant properties such as viscosity or volatility. Rarely does the product distribution exceed 90 wt. % monoalkylated naphthalenes. Viscosity and volatility may alternately be modified by obtaining a first fraction enriched in monoalkylated naphthalenes and a second fraction enriched in dialkylated naphthalenes and combining the first fraction and the second fraction in a specified ratio to produce a modified alkylated naphthalene composition having a targeted value of one of the viscosity or the volatility. The first fraction and the second fraction may be obtained by fractional distillation of a first alkylated naphthalene composition to afford an overhead fraction and a bottoms fraction.
