| titleOfInvention | Purification of m-dinitrobenzene |
| abstract | PURPOSE: Crude m-dinitrobenzene is combined with sodium sulfite and a dialkylamine and they are heated in the presence of water, separated into the oil phase and the aqueous phase, then impurities are removed to give in high yield, the titled compound of high purity which is used as an intermediate. n CONSTITUTION: m-Dinitrobenzene containing o- and/or p-dinitrobenzenes is combined with sodium sulfite and a dialkylamine such as dimethylamine, diethylamine, di-n-proplylamine, di-isopropylamine and heated in the presence of water. Then, phase separation is effected and impurities included in the oil phase is removed by extraction with an inorganic acid to effect the purification of m-dinitrobenzene. The process according to the present invention is advantageous, since a dialkylamine is allowed to act simultaneously to permit the removal of unreacting substance in a shorter time. n COPYRIGHT: (C)1986,JPO&Japio |
