Surface Chemical Properties of Surface Active Aminocyclitol Derivatives

계면활성(界面活性) 아미노싸이클리톨 유도체(誘導體)의 계면화학적(界面化學的) 성질(性質)

Surface chemical properties including surface tension, Ross-Miles foaming power, foam stabilities, emulsifying properties, emulsion stabilities, effectiveness of dispersion, dispersion stabilites of the quaternary ammonium salt type deoxyaminoimositol derivatives such as sixteen kinds of dimethylafkyl-deoxyscyllo-inosityl- dimethylalkyl-2-deoxy-2-myo-inosityl-, dimethylakyl-2-deoxy-2-epi-inosityl- and dimethylalkyl-4-deoxy-4-myo-inosityl ammonium chlorides are tested. And critical micelle concentration of these compounds are estimated from the curves of surface tension and concentration. The experimental results show that the members of this class of compounds have necessary surface active properties to make them effective surfactants.
