对硝基苯甲醛制备

1.以对硝基甲苯、乙酐为原料，经氧化、水解而得。

2. 以对硝基甲苯、乙酐为原料，冰醋酸为溶剂。将三者混匀且完全溶解。冷却到5℃以下，搅拌下缓慢加入硫酸，并控制温度不超过15℃，加完硫酸后继续搅拌冷却到0℃，然后分次少量加入三氧化铬，控制加入速度，使温度不超过10℃，加完后继续搅拌半小时，将混合物倒入适量冰水中，析出结晶，过滤，所得结晶用冷水洗至无色，再用4%的碳酸钠溶液洗涤，充分搅拌后过滤，用冷水重新洗涤结晶至中性，所得结晶为对硝基苄基  二乙酸酯。将对硝基苄基  二乙酸酯与水、乙醇和浓硫酸混合，回流2h，每kg对硝基苄叉-二乙酸酯需水、乙醇各2L，浓硫酸200ml 。回流结束后，静置，滤出结晶，用水洗至中性，即为对硝基苯甲醛粗品：反应式为：

粗品对硝基苯甲醛用1∶ 1乙醇重结晶，即得成品。
