Excess and partial excess molar volumes of mixing trimethyl- and triethylphosphate with water

  • 51 Accesses

Abstract

Excess and excess partial molar volumes of mixing of the systems trimethylphosphate (TMP) and triethylphosphate (TEP) with water were determined at 15, 20, 25, 30 and 35°C. Negative deviation from ideal behavior were observed for the two systems studied, with a minimum at x TMP =0.40 and x TEP =0.35. Excess volume values in general decrease with temperature, and are smaller for the TMP-water system.
