摘要: A process is described for the production of synthetic basestocks from an alpha-olefin feedstock with carbon number in the range C.sub.7 -C.sub.30 the feedstock having origin in an ethylene polymerization process, the process comprising contacting the feedstock with a solid or soluble cationic AlCl.sub.3 catalyst. After separation and distilling out of the light fraction of the oligomer, a basestock of excellent viscometric, rheological and thermal stability properties is obtained. The basestocks so obtained are also described.

摘要: The present invention relates to a process for obtaining a catalyst of high activity based on a mixture of supports, more specifically, the mixture of supports being Al2O3 plus MgCl2, intended for the production of polyolefins. The catalyst of the present invention involves the use of a spherical support based on special alumina that serves as a porous matrix, which is impregnated, by precipitation, with magnesium chloride by dissolving the latter in ethers and/or alcohols.
