EFFECT OF PHASE-TRANSFER CATALYSTS ON THE INTERFACIAL-TENSION OF WATER TOLUENE SYSTEM

The effect on the interfacial tension of the water/toluene system has been studied at 25-degrees-C in the presence of four phase-transfer ca talysts i.e. tricaprylmethyl ammonium chloride, hexadecyltrimethyl amm onium chloride, hexadecytrimethyl ammonium bromide and hexadecyltribut yl phosphonium bromide. The interfacial tension of aqueous phenol/reso rcinol-toluene in the presence and absence of tricaprylmethyl ammonium chloride has also been reported. Attempt has been made to elucidate t he change in volumetric rate of extraction with different catalysts fo r two phase reactions, on the basis of interfacial tension.
