Glass Ball as Bullet Solubility System: Chlorine with Poly(vinyl chloride) (PVC)
Components:
   (1) Chlorine; Cl2; [7782-50-5]  NIST Chemistry WebBook for detail
   (2) Poly(vinyl chloride) (PVC); ; [9002-86-2]  NIST Chemistry WebBook for detail
Original Measurements:
   S. Wachi, H. Morikawa and H. Inoue, AI.Ch.E. Journal. 34, 1683-1690 (1988).

 Variables:
   Temperature = 293 K - 345 K
   Concentration = 0-35 mol/m3

 Prepared By:
   Yu. P. Yampol'skii

 Experimental Remarks:
   In the subatmospheric 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.

 Method/Apparatus/Procedure:
   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).

 Source and Purity of Materials:
   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.
