Summary

Results of experiments carried out in small silica and pyrex vessels are presented, continuing the work reported in Part I of the series. The results are correlated roughly by means of a radical-molecule mechanism. A model based on this mechanism allows a prediction of the results on the full-scale to be carried out.

The effect of increasing surface-age on the reaction has been determined with reasonable reproducibility. A large number of by-products have been detected and chromatograph assignments made. In general, the by-products represent a small part of the organics conversion to carbon tetrachloride.
