CAS: 528-75-6
分子式: C7H4N2O5
分子量: 196.12
沸点: 190℃(10
熔点: 65-71℃
中文名称: 
2,4-二硝基苯甲醛
间二硝基苯甲醛
英文名称: 
2,4-dinitrobenzaldehyde
m-Dintrobenzaldehyde
2,4-dinitro-benzaldehyd
性质描述: 白色或浅黄色结晶。熔点72℃,沸点190℃/10mmHg 。易溶于乙醇、乙醚,溶于苯和冰醋酸,微溶于水。受热易升华。
生产方法: 以N,N-二甲苯胺为起始原料,经下列步骤制得该品。将N,N-二甲苯胺和浓盐酸配成溶液,加入冰块冷至5℃。搅拌,缓缓加入亚硝酸钠溶液,保持8℃以下,1h加完,再放置1h,过滤。滤饼先用盐酸洗涤,后用乙醇洗涤,在空气中干燥,得对亚硝基二甲苯胺盐酸盐。把上述盐酸盐及无水碳酸钠加入乙醇中,加热半小时,过滤。将滤液和2,4-二硝基甲苯一起搅拌加热5h,冷却后滤出缩合物,用乙醇重结晶一次。将缩合物加入盐酸中,通入水蒸气15min,冷却,倾出水层,再加稀盐酸通入水蒸气搅拌。最好滤出固体物,水洗,在真空干燥器中干燥,得2,4-二硝基苯甲醛。
用途: 用于有机合成、照相、制备席夫碱(Schiff's bases)。
