摘要：Elutions of vinyl chloride monomer (VCM) from polyvinyl chloride (PVC) resin pipes in the absence and presence of chlorine in water were compared by the method of head space analysis. The VCM concentrations in the absence of chlorine in water after contact with PVC pipes were dependent on the residual VCM contents in these pipes. In the presence of chlorine, however, lower concentrations of VCM in comparison with those values obtained in the absence of chlorine were observed for all PVC pipes examined. The decrease in both VCM and chlorine concentrations were also recognized when these chemicals were mixed in water, especially under acidic conditions. Gas chromatography-mass spectrometry of ether extract from the aqueous solution showed the reaction product of VCM and chlorine to be 2, 2-dichloroethanol.
