초록
본 실험에서 반응성 계면활성제는 비이온성 계면활성제인 polyoxyethylene(23) lauryl ether(Brij 35)와 polyoxyethylene(20) stearyl ether(Brij S20)를 acrylic acid 또는 3-butenoic acid를 사용하여 합성하였다. 계면활성제는 FT-IR과 1H-NMR로 확인하였으며, 물성은 임계미셀농도, 유화력, 기포력을 측정하였다. 합성한 반응성 계면활성제의 표면장력과 임계미셀 농도는 35 dyne/cm~41 dyne/cm에서 1.0 × 10-4 mol/L~9.7 × 10-5 mol/L의 값을 가진다. 또한, 계면활성제의 유화력은 대두유, 벤젠, 모노머에서 측정하였으며, 기포의 초기 높이 및 5 min 후의 높이를 측정하여 비교하였다.
In this paper, reactive surfactants were synthesized by using acrylic acid or 3-butenoic acid as nonionic surfactants, polyoxyethylene(23) lauryl ether (Brij 35) and polyoxyethylene(20) stearyl ether (Brij S20). The synthesis of surfactants was confirmed by FT-IR and 1H-NMR. The surface tension, emulsifying property, and foam power and stability were also measured. The surface tension value was 35~41 dyne/cm at an critical micelle concentration (cmc) which was measured as 1.0 × 10-4~9.7 × 10-5 mol/L using a surface tension method. The emulsifying power of synthesized surfactant was measured with benzene, soybean oil and monomer. Also, the initial height of the bubbles and the height after 5 minutes were measured and the values were compared with each other.
