Continuous flow hydrolysis of phosphate esters using membrane reactor containing cyclodextrins

摘要

Membranes of poly(oxa-p-phenylene-3,3-phtalido-p-phenylenxoxa-p-phenylenenexoxi-p-phenylene) (PEEK-WC) containing #beta#-cyclodextrin (#beta#-CD) derivatives (O-octyloxycarbonyl #beta#-CD and monotosyl #beta#-CD) have been prepared to investigate their catalytic behaviour towards the p-nitrophenyldiphenylphosphate (PNPDPP) hydrolysis. Membranes containing CD lead to very high reaction rate during the hydrolysis of PNPDPP. Best results were obtained using monotosyl #beta#-CD 2.5 wt% containing membrane at pH 8.
