Thermodynamic function of microemulsions in sodium salt of dialkylphosphoric acid extractant systems

Abstract

Free energy of transfering alcohol from organic phase to interface (DG0?) for the microemulsion systems containing saponified dialkylphosphoric acid extractants NaDEHP, NaEHEHP and NaDTMPP has been measured. The effects of the type of extractant, organic solvent, length of alkanes, length of alcs. and temperature on the thermodn. function have been discussed. The free energies of transition of the sodium salts of these acid at the organic/ interface were calculated in different organic solvents.

Key words: EXTRACTIVE AGENT, PHOSPHONIC ACID ESTER, THERMODYNAMIC FUNCTION, PHOSPHORIC ACID ESTER, ETHYLHEXYL PHOSPHONIC ACID MONOETHYL HEXYLESTER, MICROEMULSION, TRIMETHYLPENTYL PHOSPHINIC ACID
