INTERFACIAL TENSION OF ALIPHATIC ESTERS WITH SURFACE ACTIVE AGENTS. PART II

The interfacial tension measurements of some aliphatic esters have been carried out against aqueous soap solutions. A number of esters, e.g. propyl, butyl and amyl acetates etc. show an exceptional behaviour in a sense that the tension increases to a sharp maximum initially with increasing soap concentration in dilute solutions, followed by a great lowering and thereafter reaching a limiting value.
