Solubility System:
Hydrocarbon gases C1-C4 with Poly(vinyltrimethyl silane) (PVTMS)
Components:
(1) Hydrocarbon gases C1-C4; ; []
NIST Chemistry WebBook
for detail
(2) Poly(vinyltrimethyl silane) (PVTMS); ; [25036-32-2]

Evaluator:
Yu. P. Yampol-skii, A. V. Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences, April, 1994
Critical Evaluation:
The solubility of gaseous hydrocarbons in PVTMS has been measured using three different techniques: volumetric,
1
gravimetric,
2,4
and inverse gas chromatography.
5-8
The data for the following gases are available: methane [74-82-8],
1
acetylene [74~86.2],
2-4,8,9
ethylene [74-85-1],
2-5,7-9
ethane {74-84-0],
2-5,7-9
propadiene [463-49-0],
2-4,8,9
propyne [74-99-7],
2-4,8,9
propene [115-07-1],
2-5,7-9
propane [74-98-6],
2,9
n
-butane [106-97-8].
5,7
Except propane and butane for which the dual mode sorption isotherms have been obtained,
4,6
the solubility of all other gases was measured in the range of pressure corresponding to the linear part of the sorption isotherm, i.e., the solubility coefficients have been reported. There is a general tendency for the solubility to increase with the critical temperature of gases, the variation of solubility with critical temperature is shown below. Values of critical temperature were taken from Ref. 10.
