摘要：

New polyethylene glycol ammonium and phosphonium salts (PEG-quat) phase-transfer catalysts were synthesized and their catalytic activity was studied in a dehydrohalogenation liquid-liquid phase-transfer system. The catalytic activity of the PEG-quat catalyst depended on the nature of the quaternary salt, the most effective compounds being those in which only one hydroxyl group is replaced by the quaternary function.
