Abstract

In this study, we synthesized reactive surfactant which have functional radical group for effective chemical reaction. Reactive surfactant have been synthesized using synthesis of polyoxyethylene lauryl ether(POE 23) which is nonionic surfactant and methacrylic acid, acrylic acid. benzene was used as the solvent, p-TsOH was used as the catalyst. synthesized surfactant was confirmed by FT-IR, $^1H$-NMR spectra, and elemental analysis. Evaluation of physical properties was measured HLB, cloud point, surface tension, the critical micelle concentration, emulsifying power. HLB number was evaluated 11.62 to 12.09 range. The Critical Micelle Concentration(cmc) values evaluated was $1{\times}10^{-4}{\sim}5{\times}10^{-4}mol/L$ by surface tension method. The cloud point was $35^{\circ}C$, $39^{\circ}C$ each. The emulsifymvcqa ing properties of the synthesized surfactants was lower than polyoxyethylene lauryl ether. In addition, soybean oil was better than benzene. The experimental results confirmed the ester bond, the yield of 93.27%, 94.49% was found.

이 연구에서는 계면활성제에 작용기를 첨가하여 유화제 뿐만 아니라 합성에서의 모노머로 작용할 수 있는 반응성 계면활성제를 합성하였다. 반응성 계면 활성제는 메타아크릴 산, 아크릴산과 비이온성 계면 활성제인 폴리 옥시 에틸렌 라우릴 에테르 (POE 23)를 사용하여 합성되었으며 벤젠을 용매로서 사용하였고, P-TsOH를 촉매로서 사용 하였다. 합성된 계면 활성제는 FT-IR, $^1H$-NMR 스펙트럼, 원소 분석을 하였다. 물성 평가는 HLB, Cloud point, 표면 장력, 임계 미셀 농도를 측정 하였다. HLB 값은 11.62~12.09 범위로 평가 하였다. cmc 값은 표면 장력 법으로 측정하였을 때 $1{\times}10^{-4}{\sim}5{\times}10^{-4}$의 값을 가졌다. 실험을 통해 측정된 Cloud point은 35, $39^{\circ}C$ 이었다. 합성 계면 활성제의 유화 특성은 polyoxyethylene lauryl ether보다 낮았다. 또한, 유화력은 벤젠에서 보다 대두유에서 더 좋았다. 실험결과 합성 수율은 93.27 ~ 94.49%로 확인되었다.
