Hexadecyl Pyridinium Bromide의 임계미셀농도에서 온도의 효과

The Effect of Temperature on the Critical Micelle Concentration of Hexadecyl Pyridinium Bromide

화장품과 유처리제 등에 응용할 수 있는 계면활성제인 hexadecyl pyridinium bromide를 사용하여 온도 $40{\sim}60^{\circ}C$ 범위에서 임계미셀농도를 적하법으로 측정한 결과를 이용하여 미셀형성에 따른 열역학적 양을 다항식으로 계산하였다.

Surfactants can be used as a cosmetics and chemical dispersants. The variation of critical micelle concentration(CMC) with temperature for hexadecyl pyridinium bromide over the range $40^{\circ}C$ to $60^{\circ}C$ has been measured by drop methods. Thermodynamic quantities for micellization of hexadecyl pyridinium bromide in water have been calculated by polynominal equation.
