Vapor-Liquid Equilibria for Binary Systems Made of N,N-Dimethylformamide with Acrylonitrile or Trichloroethylene.

Abstract

Vapor-liquid equilibrium relations were measured for binary systems made of N,N-dimethylformamide with acrylonitrile or trichloroethylene at 98.66kPa by the dew-bubble point temperature method. Combining the dew point temperature curve and the bubble point one, vapor-liquid equilibrium relationships were obtained for the binary systems. Literature data are not available for the systems of the present study. The present experimental method does not require any analytical instrument for the vapor-liquid equilibrium measurements. For the correlation of the experimental data, the Wilson equation was applied.

Confirmation of universality of time–humidity superposition principle for various water‐absorbable polymers through dynamic viscoelastic measurements under controlled conditions of relative humidity and temperature

“…Another unique point of the system is the ability to control the RH of the sample box in an arbitrary fashion 26–29. This stepwise change in the RH is useful for an investigation of frequency dispersion of the mechanical property under the same humidity condition during the humidity scanning experiment.…”
