    摘要： 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.

    摘要： 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.

    摘要： 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. Improvements in thermal stability are observed over a wide range of catalyst concentration. Concentrations of about 10 weight percent are preferred with aluminum chloride catalyst.

    摘要： 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.
