상전이촉매 용액내에서 N-actey-DL-alanine-p-nitrophenyl Ester의 가수분해반응에 미치는 o-Iodosobenzoate 이온의 영향 = The Effect of O-Iodosobenzoate Ion on Hydrolysis of N-aetey-DL-alanine-p-nitrophenyl Ester in Phase Transfer Catalyst

다국어 초록 (Multilingual Abstract)

This study is mainly focused on phase transfer catalysis(PTC) effects of ethyl tri-octyl ammonium bromide(ETABr) and ethyl tri-octyl ammonium mesylate(ETAMs) solution including o-iodosobenzoate ion(IBθ) on hydrolysis of N-actey-DL-alanine-p-nitrophenyl ester(NAAP) in Carbonate buffer(pH 10.4).
The first order rate constants(kEIB) of the reaction in ETABr and ETAMs solution mediated by o-iodosobenzoate ion(IBθ) are increased by about 220~250 times as compared with those in aqueous solution(kwIB) respectively. The reaction rate of NAAP was very faster than that of p-nitrophenylpropionate(p-NPV) under the same condition(pH 7.4).
We have a apparent evidence that aggregation ability of this o-iodosobenzoate ion(IBθ) to ETABr and ETAMs is very high and the reaction orders for three substrate, NAAP, IBθ and ETABr are respectively larger than unit.
