The synthesis of phenoxymethyl ethylene carbonate from carbon dioxide and phenyl glycidyl ether was investigated in a semi-batch reactor using crosslinked polystyrene beads containing pendant quaternary ammonium salts as catalysts. The catalysts were prepared by suspension copolymerization of styrene, divinylbenzene (DVB) and vinylbenzyl chloride (VBC), followed by quaternization using trialkylamines. The influence of VBC and DVB concentration, the structure of trialkylamine, and the type of solvent, on the catalytic behavior are discussed. A kinetic study was also carried out to better understand the reaction steps. [ABSTRACT FROM AUTHOR]

A kinetic study on the absorption and reaction of carbon dioxide with 2,3-epoxypropyl phenyl ether (phenyl glycidyl ether, PGE) in benzene solution has been carried out at room temperature in the presence of tricaprylylmethyl ammonium chloride (Aliquat 336) as catalyst. A simple method of measuring the absorbed volume of CO was proposed to obtain the reaction rate constant, and it was based on the film theory accompanied by a chemical reaction. The enhancement factor (β-N/N ) increased with increasing bulk concentration of PGE and Aliquat 336. The flux of CO was proportional to the agitation speed. [ABSTRACT FROM AUTHOR]
