Mischungsfunktionen im binären System N‐Methylcaprolactam – n‐Tetradecan

Mixing Functions of the Binary System N-Methylcaprolactam – n-Tetradecane
The liquid-liquid equilibria(LLE) and the vapour-liquid equilibria(VLE) at 60°C were measured in the binary system N-methylcaprolactam (1) – n-tetradecane (2). The enthalpy of mixing HE of the same system was extrapolated from HE – measurements of N-methylcaprolactam with other alkanes. The limiting activity coefficients f∞1 and f∞2 were obtained by extrapolation from values of resp. in other alkanes. For a comparison the vapour pressures of the mixture were calculated by model equations with constants from the two limiting activity coefficients and with temperature dependent constants extracted from the LLE and HE measurements.
