説明

Author investigated the surface activities of the polyoxyethylene ethers which have the oxyethylene chains of definite lengths. Mono, di, tri, tetra and penta oxyethylene ethers of lauryl, cetyl, oleyl alcohols and nonylphenol, synthesized in our labolatory, were dissolved or suspended in water and the surface tension of the solutions was measured by using du Nouy's surface tension meter. With the exception of cetyl ethers and mono and di oxyethylene lauryl ethers, the surface tensionconcentration curves of the solutions showed same characteristics as those of ordinary surface active agents. Namely, change in the surface tension is little at higher concentration, while it increases rapidly as the concentration decreases for the range below c.m.c.<BR>Furthermore, it was observed that the surface tension of the solutions of paired ethers containing lauryl-oleyl, oleyl-nonylphenyl, and nonylphenyl-lauryl, having tetraoxyethylene chain respectively, was in a range between those of individuals of the pair ethers. Exploratory experiments were also carried out with other combinations and the effect was studied.
