Abstract
For substances that may decompose in the industrial environment forming highly toxic secondary pollutants a computer simulation of the decomposition process gives useful information to the industrial hygienist. This paper presents a model for the decomposition of a gaseous substance contacting a hot surface. Application of the model to carbon tetrachloride being oxidized to phosgene etc. on a silica surface indicates that the decomposition may be of hygienic importance from circa 200–250°C, a much lower temperature than expected from published laboratory investigations of CCl 4 . Conventional laboratory investigations are shown to be of limited value for health hazard assessment purposes under varied conditions.This publication has 0 references indexed in Scilit:
