Values of a type of Henry's constant (actually H
–1
) were also given in the form of the following equation:
C = k·
p
C = Equilibrium concentration,
g
ethene/100 m1 of solvent
k = A type of Henry’s constant
p
= Gas partial pressure, atm
Method/Apparatus/Procedure:
The source of the data was stated to be Ref. 1. Only a graph is available in that reference. It was also stated that the Hoechst company (Germany) used these values of solubility.
There were no details of apparatus or procedure.
Source and Purity of Materials:
