Method for the removal of acetylenes from olefins using ionic liquid-based solution |
| 초록 |
The removal of acetylenic hydrocarbons in olefins is very important. Because terminal alkynes often serve as catalyst poisons in the process of producing polyolefins and also lower the product quality of polyolefins. Various nonimidazolium ionic liquids were tested as extractants for the removal of alkynes from isoprene. When the feed containing 1% of isopropenyl acetylene (IPA) in isoprene was contacted with nonimidazolium ionic liquids, about 50~70% of IPA was extracted from isoprene to the ionic liquid layer. Further more we used metal containing nonimidazolium ionic liquids. The extraction ability of the ionic liquids was greatly enhanced, resulting in the removal of 80~90% IPA in the feed. |
