Abstract: The kinetics of dehydrochlorination of polyvinyl chloride is frequently monitored by means of hydrogen chloride which is split off and expelled from the reaction vessel with the appropriate carrier gas. Hydrogen chloride is in turn trapped in an aqueous solution and its amount is determined by conductometric or Potentiometrie titration. This paper points out the influence of the eliminated hydrogen chloride by its adsorption on the surface of glass parts of the device on results of the measurement. A device for countercurrent absorption of hydrogen chloride from the carrier gas in silver nitrate solutions is also described.
