Phenyl glycidyl ether와 이산화탄소의 부가반응에서 고정화된 4급 암모늄염 촉매의 응용
Synthesis of 5-Membered Cyclic Carbonate by Addition Reaction of Phenyl Glycidyl Ether and Carbon Dioxide
In the present study, the synthesis of phenoxy methyl ethylene carbonate from carbon dioxide and phenyl glycidyl ether was investigated using polymer-immobilized quaternary ammonium salts as catalysts. The catalysts were prepared by partial emulsion copolymerization of styrene(ST), divinylbenzene(DVB) and vinylbenzyl chloride(VBC). The influence of VBC concentration, the degree of crosslinking, partial polymerization time and the structure of trialkyl amine of quaternary salts on the catalytic behavior was discussed.
