Conditions:

Room Temp: 303 - 343 $\pu{K}$
Pressure: 0 - 26 $\pu{kPa}$

Compiler:

A.K. Bokarev

Methodology:

Sorption was determined by a gravimetric method using a Calm microbalance (Model KG). Corrections were made for buoyancy effects.

Sample Information:
  1. Gases: purity 99.99%. EC (Ethocel 10 cp): Dow Chemical Co., contained 48%-49.5% ethoxy groups, $\rho = \pu{1.13 g mL-1}$, $T_{\rm{g}}$ = 396 K.
Measurement Errors:

Ambient temperature: No information given.

System Components:
  1. Ethane, $\ce{ C2H6 }$ ; [74-84-0] NIST WebBook
  2. Ethyl Cellulose, $\ce{ C23H24N6O4 }$ ; [9004-57-3] NIST WebBook
