Methodology:
Physical sorption of chlorine in PVC was determined using the constant volume cell method. The pressure changes were measured by means of a sensor (Toyoda-kouki PMS-5,5H).
Sample Information:
- PVC (SC-16, DP-600) supplied by Kaneguchi Chemical Industries Co was prepared by suspension polymerization. No information on the purity of chlorine is given.
System Components:
- Chlorine, $\ce{ Cl2 }$; [102-30-7] NIST WebBook
- Poly(vinyl chloride) (PVC), $\ce{ (C2H3Cl)n }$; [9002-86-2] NIST WebBook
Experimental Data
In the sub-atmospheric range of pressure the concentration of dissolved chlorine C(mol/m3) obeyed the following equation:
C=Sy,
where y is the concentration of Cl2 in gas phase (mol/m3). Temperature dependence of the solubility coefficient S is given below.
The following equation was obtained for the temperature dependence of S:
S=0.280 exp(ΔHs/RT).
where ΔHs is the heat of sorption, is 10,480 kJ/mol.
