Regression curves:

Vapour pressure [bar] as a function of concentration [% dry mass]:

30 °C:

y = -1E-06 x² - 7E-05 x + 0.0424

R² = 0.9995

50 °C:

y = -4E-06 x² - 0.0002 x + 0.123

R² = 0.9964

The fugacity coefficient of Vinasses for the different concentrations were calculated by relating the measured vapour pressures to the vapour pressure of pure water. Provided that fugacity coefficients are constant for the whole temperature range the following vapour pressures were calculated:
