Studies on explosive reaction of vinyl chloride mixed with oxygen

Abstract

The explosion limits of vinyl chloride mixed with oxygen are determined at reduced pressures by the admission method. Isochors and isotherms of the explosion limit and also the colors of ignition flames are shown. There is no essential difference between the behavior of vinyl chloride mixed with oxygen and that of ethylene mixed with oxygen except the generation of hydrogen chloride under the slow reaction. Patterns of these explosion limits are similar to each other. The induction periods in the explosion peninsula of vinyl chloride mixed with oxygen have also been measured and it is found that these periods are shorter than those of ethylene mixed with oxygen. The apparent activation energy of the reaction is estimated from the explosion limits of vinyl chloride mixed with oxygen according to Semenoff's theory and its value, E, is about 34kcal.
