Abstract

N-propyl-N,N-dimethylethanolamine was directly ultrasonicated in acidic water for 6 minute to give clear stock solutions. The catalytic hydrolysis of N-propyl-N,N-dimethylethanolamine was studied at $30{\sim}55^{\circ}C$ in the presence of uni-lamellar vesicle and mixture of uni- and multi-lamellar aggregates. The difference of rate between uni- and mixture was observed, where uni-lamellar reaction was more catalytic effect. The phase transition temperature of vesicle was $37{\sim}44^{\circ}C$. The particle size of multi-lamellar than that of uni-lamellar of biological membrane was measured more largely.

N-propyl-N,N-dimethylethanolamine의 용액을 만들기 위해 산성 조건 하에서 6분간 초음파처리하여 제조하였다. N-propyl-N,N-dimethylethanolamine 의 촉매 가수분해는 온도 $30{\sim}55^{\circ}C$에서 uni-lamellar vesicle과 uni-lamellar와 multi-lamellar가 뭉쳐진 혼합물에서 연구되었다. 이들의 차이는 촉매효과에 대해 multi-lamellar보다 uni-lamellar에서 영향이 크게 나타났다. Vesicle의 상전이 온도는 $37{\sim}44^{\circ}C$이며, multi-lamellar의 분자 입자의 크기는 uni-lamellar의 입자의 크기보다 크게 나타 났다.
