✦ Synopsis

The cause of complete burnout of methanol-bromine mixture in the tube with diameter of 35 mm is shown. The study in the paper chemistry process of mixture ignition in quartz tube explains vigorous "anaerobic" burnout of methanol-bromine mixture when the tube is elongated up to 500 mm that is an order higher than the limit depth of flame penetraton into the tube at combustion of single liquid. The results of this study show that visual observations of methanol-bromine mixture combustion in the quartz tube as an engineering method for hazard estimation of halogenation technological processes similar to bromination process of m-nitroacetophenone in methanol. The study permits us to conclude that to evaluate the real hazard of methanol halogencontaining mixture compositions in different technologies, detonation tests for these mixtures are required.
