Abstract: This invention provides a method for producing a lubricant composition that is comprised of a continuous phase and a discontinuous phase. The method involves mixing together high viscosity ester, ether or combination thereof, and polar diluent or solvent, to produce a solution. The solution is then added to a low viscosity Group IV base oil to produce a discontinuous phase dispersed throughout a continuous phase.

Abstract: Solid, waxy 1-olefins may be converted to low viscosity liquid products by carrying out a double bond isomerization in the presence of a solid acidic catalyst such as an acidic clay or a zeolite under mild conditions. The olefin isomer products are useful in the formulation of well fluids such as drilling muds, especially useful in offshore drilling. The preferred oils for making up the well fluids are formulated with a hydrocarbon oil blend of the low viscosity olefin isomer together with a C.sub.12 to C.sub.18 paraffinic hydrocarbon of petroleum origin and a C.sub.10 to C.sub.32 olefin such as tetradecene-1. The fluids exhibit good biodegradability and are non-toxic to marine organisms; they also meet viscosity and pour points specifications for formulation into oil based muds.

Abstract: Novel homopolymer and copolymer compositions produced from the polymerization of non-conjugated dienes have been discovered. The novel compositions are produced by an equally novel process comprising cyclopolymerization of non-conjugated dienes employing reduced valence state Group VIB metal oxide catalyst on porous support. The preferred catalyst comprises carbon monoxide reduced chromium on silica. Copolymers are formed by copolymerization of non-conjugated dienes with 1-alkenes in contact with the activated chromium on silica catalyst. The compositions are useful as lubricants and additives.

Abstract: A process for the production of hydrocarbon lubricant basestock comprises contacting C.sub.2 to C.sub.20 alpha-olefin feedstock, or mixtures thereof, e.g., 1-decene, under heterogeneous oligomerization conditions with a catalyst comprising halides of a metal component anchored on an adsorbent inorganic oxide solid, e.g., silica, by an oxygen-metal bond to provide a reaction mixture containing said hydrocarbon lubricant basestock. The catalyst is prepared by contacting the inorganic oxide solid with organic metal halide of the formula RMXY wherein R is alkyl or aryl, M is aluminum, X is halogen and Y is selected from the group consisting of halogen, alkyl, alkenyl, aryl, alkoxy, and amido moieties.

Abstract: A process for the production of polyisobutylene (PIB) from isobutene-containing feed comprises contacting said feed with a catalyst composition comprising halides of a metal component anchored on an adsorbent inorganic oxide solid by an oxygen-metal bond to provide a reaction mixture containing said polyisobutylene; and thereafter separating and recovering said polyisobutylene.

Abstract: A novel method to prepare a solid acid catalyst through the reaction of a metal-alkyl halide species and the surface hydroxyl group of a solid support is disclosed. Lewis acidic metals, e.g., B, Al and Ga, etc., can then be anchored on the surface via the formation of an oxygen-metal bond. The solids containing these metals can be used as catalysts that will catalyze organic compound coversion reactions, e.g., Friedel-Crafts type reactions, olefin oligomerization, aromatic alkylation and acylation, alkane alkylation and isomerization reactions.

Abstract: Aromatic compounds are alkylated with C.sub.20 -C.sub.1300 olefinic oligomers using an acidic alkylation catalyst to produce alkylated aromatic products, usually alkylaromatic hydrocarbons. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with reduced metal oxide catalyst, preferably reduced chromium oxide on a silica support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. If the alkylation is carried out under certain combinations of conditions, especially using a Lewis acid catalysts such as aluminum trichloride and at higher temperatures, the alkyl portion of the product will undergo isomerization. The alkylaromatic compositions show improved thermal stability and are useful as lubricant basestocks and additives for improved antiwear properties, antioxidant and other properties.

Abstract: The thermal and oxidative stability of HVI-PAO olefin oligomers is improved by reaction of the oligomerization mixture containing the olefin oligomer, dimer and isomerized but unoligomerized olefin with an aromatic compound such as toluene, xylene or naphthalene. The reaction is carried out in the presence of an acidic catalyst, which may be heterogeneous solid catalyst such as an acidic clay or a crystalline zeolite such as MCM-22, a homogeneous Friedel-Crafts catalyst such as AlCl.sub.3, BF.sub.3 or their complexes or a supported catalyst such as AlCl.sub.3 on graphite or silica. The reaction improves the yield and thermal stability of the lube range products. The olefinic oligomer mixture which is reacted with the aromatic compound is prepared from 1-alkene oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica.

Abstract: Liquid olefin oligomers are produced by the oligomerization of C.sub.2 -C.sub.5 alpha olefin alone or with ethylene as a co-monomer. The oligomers having high viscosity index and a structure which is characterized by a regio-irregularity of at least 20 percent, usually from 20 to 40 percent. The olefins are oligomerized with a reduced valence state chromium oxide catalyst on a silica support, usually at a temperature from 90.degree. to 250.degree. C., although lower temperatures can also be used with ethylene as a con-monomer. The liquid oligomerization products can be produced in wide range of viscosities including the direct production of low viscosity lubricants having high viscosity index.

Abstract: Alkylaromatic lubricant products are produced by the reaction of a long chain alkyne such as octyne, decyne or dodecyne over a reduced Group VIB metal oxide catalyst, preferably reduced chromium on silica. The products, which are predominantly n-alkyl substituted, possess excellent thermal and oxidative stability and may be used as lubricant base stocks and viscosity improvers.

Abstract: A process is disclosed for improving the thermal stability of polyalpha-olefin lubricants by contacting the lubricant with an acidic catalyst for a time and at a temperature sufficient to achieve the skeletal isomerization of the molecular structure of the lubricant. The reaction is carried out preferably on unhydrogenated synthetic lubricants in contact with Lewis acid catalysts. Following the isomerization reaction, the unsaturated lubricant is hydrogenated to produce lubricant with better thermal stability. Surprisingly, when the isomerization reaction is carried out using unsaturated oligomer produced from the oligomerization of alpha-olefins in contact with reduced Group VIB metal oxide catalyst on porous support as starting material the viscometric properties of the lubricant, e.g., viscosity and VI, are not significantly altered, although the thermal stability of the lubricant is substantially increased. The reaction of the present invention may be carried out in the presence of a solvent or neat.
