标题:Process for the synthesis of 1-amino-3-halo-4,6-dinitrobenzene
发明人：HARGIS ANNALISA; RITTER JOACHIM C
权利人:HARGIS ANNALISA; RITTER JOACHIM C; DU PONT
摘要:A process is provided for the preparation of 1-amino-3-halo-4,6-dinitrobenzene and related compounds by monoamination of dihalodinitrobenzenes by ammonia in the presence of solvent and water. Using glycol as a solvent for the dihalodinitrobenzene and feeding ammonia at a rate at which it is consumed allows for the synthesis of high purity product, such as 1-amino-3-chloro-4,6-dinitrobenzene, at high yields.

摘要:A process is provided for the preparation of 1,3-diamino-4,6-dinitrobenzene by amination of 1,3-dihalo-4,6-dinitrobenzene. The presence of water advantageously results in a highly pure product, free or essentially free of glycol ether impurities.

发明人：RITTER JOACHIM C
权利人:DU PONT
摘要:A process is provided for the preparation of 1,3-dihalo-4,6-dinitrobenzene by the nitration of 1,3-dihalobenzene. The direct isolation of highly pure 1,3-dihalo-4,6-dinitrobenzene is accomplished without a water or ice quench, and involves the use of at least one equivalent of SO 3 during the reaction, slow crystallization, and isolation of product from a cold crystal slurry.

标题 :Catalytic reduction of dinitrobenzenes using a noble metal catalyst and iron or iron salts
发明人：THEODORIDIS GEORGE
权利人:FMC CORP
摘要:There is provided an improved process for the reduction of optionally substituted dinitrobenzenes to the corresponding nitroanilines with high yields which comprises contacting the dinitrobenzene with hydrogen in an acidic medium in the presence of a catalytic amount of a combination of a noble metal hydrogenation catalyst, and iron or an iron salt. Isomer specific reductions may be achieved with those compounds containing suitable directing substituents. The 2-halo-5-nitroanilines which may be produced in this process may be converted via a multi-step synthesis to useful 1-aryl-4-substituted 1,4-dihydro-5H-tetrazol-5-one herbicides.
