Treatment of contaminated hydrocarbon from olefin polymerization |
| abstract |
In conventional olefin polymerization using TiCl3-containing Ziegler type catalysts, the catalyst-containing reaction product may be de-ashed by treatment with titanium-solubilizing compounds such as alcohols and the polymer product from the de-ashing step washed with a hydrocarbon to separate it from catalyst residue. It is desirable to treat the dirty hydrocarbon wash liquid to recover purified hydrocarbon suitable for recycle to the polymerization reaction. According to this invention the dirty hydrocarbon wash liquid is treated with an epoxy compound in the presence of an alcohol and distilled to recover purified hydrocarbon suitable for recycle. |
