    摘要: A method comprising contacting an olefin wax with an oxidizing agent to produce an oxidized olefin wax, contacting the oxidized olefin wax with an odor-reducing material to produce an odor-reduced oxidized olefin wax, and removing water from the odor-reduced oxidized olefin wax. A composition comprising a product of a mixture of an oxidized olefin wax and an odor-reducing material, wherein the needle penetration of the composition is less than the oxidized alpha olefin wax in the absence of the odor-reducing material.

    摘要: A method of making an olefin oligomerization catalyst, comprising contacting a chromium-containing compound, a heteroatomic ligand, and a metal alkyl, wherein the chromium-containing compound comprises less than about 5 weight percent chromium oligomers. A method of making an olefin oligomerization catalyst comprising a chromium-containing compound, a nitrogen-containing compound, and a metal alkyl, the method comprising adding a composition comprising the chromium-containing compound to a composition comprising the metal alkyl. A method of making an olefin oligomerization catalyst comprising a chromium-containing compound, a nitrogen-containing compound, and a metal alkyl, the method comprising abating all or a portion of water, acidic protons, or both from a composition comprising the chromium-containing compound, a composition comprising the nitrogen-containing compound, or combinations thereof prior to or during the preparation of the catalyst. Methods of oligomerizing olefins by contacting such catalysts with an alpha olefin.
