Abstract
IN continuation of preliminary experiments1, we have studied the monobromination of bromobenzene, chlorobenzene and fluorobenzene in the gaseous phase at several temperatures between 380° and 500° C., in the presence of artificial graphite as a contact substance, under well-defined conditions of temperature and rate of gas flow. A few typical results are given in Table 1.
