摘    要:研究了在温和条件下硒催化水合肼还原间二硝基苯(m—DNB)制备间硝基苯胺(m—NA)。考察了溶剂配比、水合肼用量、硒粉用量和NaOH用量等因素对反应的影响。结果表明,在温和条件下,硒对水合肼还原m—DNB制备m—NA有很高的催化活性和选择性。得到较适宜的工艺条件为:V(乙醇)/V(水)=10:1,2mmolm—DNB,3.1mmol水合肼,0.04gNaOH和0.02g硒粉,于75℃反应2h,m—DNB的转化率为100%,m—NA的选择性为98.7%。

关 键 词:间硝基苯胺    还原  间二硝基苯  水合肼

Abstract:The reduction of m-Dinitrobenzene (m-DNB) to m-nitroaniline (m-NA) with selenium and hydrazine hydrate was studied under mild conditions. The effects of ratio of solvents, hydrazine hydrate amount, selenium amount and NaOH amount on the reduction of m-DNB to m-NA were investigated. The results show that selenium has high catalytic activity and selectivity for the reduction under mild conditions. Under the optimized conditions of V (ethanol)/V(water) = 10 : 1, 2 mmol of m-DNB, 3. 1 mmol of hydrazine hydrate, 0. 04 g of NaOH, 0. 02 g of selenium, 75℃ and 2 h, the m-DNB conversion and the m- NA selectivity can reach 100% and 98.7%, respectively.
Keywords:m-Nitroaniline  Selenium  Reduction  m-Dinitrobenzene  Hydrazine hydrate
