摘要 |
The present invention provides a process for removing oxygenate impurities, e.g., dimethyl ether, from an olefinic product stream by converting the oxygenate impurity to a compound whose boiling point differs by at least about 5° C. from the oxygenate impurity. Typically, the compound is more readily removable from the product stream than the oxygenate impurity.
