A process for removing acetic acid from an aqueous stream containing yellow oil. According to the process, yellow oil is removed from the aqueous stream prior to the removal of acetic acid by a reverse osmosis membrane.

Disclosed in certain embodiments is an electron donor for a polyolefin polymerization catalyst. In some embodiments, a solid catalyst component includes a metal component and the electron donor that form a catalyst on a support.
