| 主权项 | 1. A method of making a catalyst for use in oligomerizing an olefin, the catalyst comprising a chromium-containing compound, a pyrrole-containing compound, a metal alkyl, a halide-containing compound, and optionally a solvent, the method comprising: abating all or a portion of water from a composition comprising the chromium-containing compound by contacting the composition comprising the chromium-containing compound with an azeotropic solvent to form a solution and subjecting the solution to an azeotropic distillation. | ||
