Abstract
Esterolysis reactions of PNPDPP (p-nitrophenyldiphenylphosphate) by DCI ( dichloroisocyanuric acid sodium salt) in borate buffer pH8.0 micellar phase were studied. The rate of hydrolysis reaction was rapidly increased by adding cationic surfactants, CTAC (cetyltrimethylammonium chloride) or CTAB (cetyltrimethylammonium bromide), to the DCI solution. Especially in CTAB micellar system, the N-Cl bond of DCI was transformed to the N-Br bond during the reaction.
DCI (dichlorolsocyanuric acid sodium salt)에 의한 PNPDPP (p-nitrophenyldiphenylphosphate)의 미셀 내에서의 분해 반응을 pH 8.0 borate 완충용액에서 속도론적으로 살펴보았다. 양이온성 계면활성제인 CTAC (cetyltrimethylammonium chloride) 또는 CTAB (cetyltrimethylammonium bromide)를 첨가하면 반응은 빠르게 촉진되었으며, 특히 CTAB의 경우는 DCI의 N-Cl 결합이 N-Br 결합으로 전환되어 반응이 진행되었다.
