초록

Sodium dodecyl polyoxyethylene α-sulfa alkanoates류 15종에 대하여 표면장력, 기포력 및 그 안정성, 유화력, 분산성, 습윤성 및 가용화능 등의 계면활성을 실험하였다. 이들 시료의 묽은 수용액에 대한 임계미셀농도는 10^-4∼10^-5mol/ℓ 범위였고 그 농도범위에서의 표면장력은 30∼47dyne/cm였으며, 일정농도 수용액에 대한 기포력 및 그 안정성, 벤젠 및 대두유에 대한 유화력, 탄산칼슘 및 산화철에 대한 분산성, 그리고 습윤력과 Orange OT에 대한 가용화능을 실험하여 검토한 결과 O/W형 유제 및 분산제로서의 응용성이 기대된다.

All the activities and physical properties including surface tension, foaming power, foam stability, emulsifying power, dispersion effect, wettability and solubilization of sodium dodecyl polyoxyethylene α-sulfo alkanoates aqueous solution were measured and critical micelle concentration was evaluated. Their cmc ebaluated by the surface tension method was 10^-4∼10^-5mo1/ℓ, and surface tension of the aqueous solution was decreased to 30∼70dyne/cm. The experimental results for foaming power, foam stability, emulsifying power in benzene or soybean oil, dispersion effect in calcium carbonate, wettability and solubilization showed a good and efficient surface active properties, and then it would be expected that these products could be applied as O/W type emulsifier, dispersion agent.
