PROCESS FOR THE PREPARATION OF 2,6-NAPHTHALENEDICARBOXYLIC ACID |
| 摘要 |
The invention is directed to a process for the preparation of 2,6-naphthalenedicarboxylic acid by liquid phase oxidation in acidic solution of 2,6-dimethylnaphthalene in the presence of a cobalt-manganese-bromine-catalyst. An oxygen containing feed gas is introduced into the reaction zone such that the oxygen content in the dry exhaust gas does not exceed 1 percent by volume.
