Abstract
The addition of carbon dioxide to phenyl glycidyl ether (PGE) was investigated in a semi-batch reactor using immobilized quaternary ammonium chloride catalysts. Five different catalysts were prepared with the following supports : (1) soluble poly(ST-co-VBC)[C1] (2) insoluble poly(ST-DVB-VBC)[C2] (3) macroporous poly(ST-DVB-VBC)[C3] (4) poly(ST-co-VBC)-MMT[C4] (5) modified MCM-41[C5]. The addition of carbon dioxide to PGE can be considered as pseudo first-order with the concentration of PGE. The order of pseudo first-order rate constant for the catalysts was C1 > C3 > C2 > C4 > C5. The activation energy for C1 to C5 catalysts was 8.6, 20.9, 19.9, 23.9, and 26.8 kJ/mol, respectively. The immobilized catalysts can be reused at least 4 successive runs without any considerable loss of their initial reactivities.
