C (エチレン部) -アルキルEDTAキレート界面活性剤

抄録

The new type of complexanes (I_{a, b, c}) having hydrophobic alkyl groups (decyl (a), dodecyl (b), hexadecyl (c)) were synthesized and their properties as surfactant were investigated.
An aqueous solution of complexane (I_b) -copper chelate (5×10^-3M) showed 0.40 in specific surface tension and 0.12 in specific interfacial tension (kerosene/water). The iron chelates of those complexanes had excellent dispersing power (TiO₂/toluene) compared with commercial dispersants.
