以苯并三氮唑和2–氯–3–硝基–吡啶为原料,合成出1–(3–硝基–2–吡啶)–1H–苯并三唑。采用元素分析、核磁共振光谱等手段鉴定了目标产物结构,并用DSC测定了产物的熔点。考察了反应溶剂、溶剂用量、缚酸剂种类、缚酸剂用量对该反应收率和产品纯度的影响。确定的最佳工艺条件为:以工业乙醇为反应溶剂,溶剂与反应物的原料比为200 mL∶0.1 mol,Na2CO3为反应缚酸剂,缚酸剂与苯并三氮唑的摩尔比为1∶1,反应时间为12 h。 1- (3-nitro-2-pyridyl) -1H-benzotriazole was synthesized from benzotriazole and 2-chloro-3-nitro-pyridine. The structure of the target product was identified by elemental analysis, nuclear magnetic resonance spectroscopy and the like, and the melting point of the product was determined by DSC. The effects of reaction solvent, amount of solvent, acid-binding agent and acid-binding agent on the reaction yield and product purity were investigated. The optimum technological conditions were as follows: industrial ethanol was used as the reaction solvent, the ratio of solvent to reactant was 200 mL: 0.1 mol, Na2CO3 was the reaction acid-binding agent, the molar ratio of acid-binding agent to benzotriazole was 1 : 1, the reaction time is 12 h.
