摘要:
In the oxidation of a substituted aromatic compound such as p-xylene using a heavy metal catalyst promoted by bromine the effluent gases from the oxidation contain methyl bromide and are treated for the recovery of bromine. A variety of methods are described whereby the bromine may be recovered, preferably in a form suitable for reuse in the oxidation process.
