Compilation - 2-Methyl-2-propanol with p-Xylene and Water (IUPAC SDS Volume 69)

SDS Volume (3773)

Volume 69. Ternary Alcohol-Hydrocarbon-Water Systems, p None

Original Measurements

Letcher, T. M.; Siswana, P. M.; van der Watt, P.; Radloff, S.; J. Chem. Thermodyn. 21, 1053 (1989).

Variables:

Room Temp: 298 $\pu{K}$

Prepared by:

A. Skrzecz

Method/Apparatus/Procedure:

The titration method was used to determine binodal curve. A binary mixture of known composition was titrated with the third component until cloudiness was observed. Tie line compositions were related to the coexisting curve; water was determined by Karl Fischer titration. The methods were described in [1].

Source and Purity of Materials:
  1. Source not specified; used as received.
  2. Source not specified; recrystallized three times.
  3. Source not specified.
Estimated Errors:

Ambient temperature: Comp. <0.005 mole fraction (estimated authors' precision on binodal curve), <0.01 mole fraction (estimated authors' precision of tie lines).
Mass concentration (m/v) (1): Not reported.
