Non-pollutional process for producing aromatic nitro compounds without using a mineral acid |
| abstract |
PCT No. PCT/JP91/01151 Sec. 371 Date Mar. 27, 1992 Sec. 102(e) Date Mar. 27, 1992 PCT Filed Aug. 29, 1991 PCT Pub. No. WO92/04313 PCT Pub. Date Mar. 19, 1992.The present invention relates to a process for producing an aromatic nitro compound by introducing a nitrogen oxide gas and ozone-containing oxygen or air into a halogenated organic solvent dissolving or suspending therein an aromatic compound, thereby subjecting the aromatic compound to nitration. By the use of a system comprising the nitrogen oxide and ozone-containing oxygen or air as the nitrating agent, the aromatic nitro compound can be produced under mild conditions without using any mineral acid. In addition, the various disadvantages due to the use of mineral acid in the conventional process can be avoided by the process of the present invention. |
