Compilation - Cyclohexane with Water (IUPAC SDS Volume 37)

SDS Volume (324)

Volume 37. Hydrocarbons in Water and Seawater, Part I, p 243

Original Measurements

Rebert, C. J.; Hayworth, K. E.; AIChE J. 1967, 13, 118-121.

Variables:

Pressure: 2.42 - 23.48 $\pu{MPa}$
Room Temp: 403 - 643.8 $\pu{K}$

Prepared by:

C.L. Young

Method/Apparatus/Procedure:

Samples of mixtures of known composition confined over mercury. Samples heated in a vapor bath and the pressure-temperature phase boundaries determined by direct observation of appearance of disappearance of a phase. Apparatus similar to that described in [1].

Source and Purity of Materials:
  1. No details given.
Estimated Errors:

Ambient temperature: δT/K = ±0.05; deltap/psi = ±1.
