| Abstract: | The effect on the chloride content of CPVC of the reaction temperature and time in the gas-solid method was studied in this article.The results showed that the content could be increased by increasing the reaction temperature and time.Considering the quality and energy consumption,100 °C and 6 h is an appropriate condition.The rate equations were derived and mechanism of the reaction was discussed.The activation energy and pre-exponential factor was calculated. |
