摘要
报道一种合成间硝基苯甲醛的新方法，将苯甲醛先制成苯甲醛缩亚胺，再硝化制得间硝基苯甲醛，该法具有异构体少、分离简便、收率高、产品纯度好的特点，较苯甲醛硝化法经济效益显著。
A new method for the synthesis of m-nitrobenzaldehyde is reported in this paper.First,Schiff-base is prepared from benzaldehyde and then,m-nitrobenzaldehyde is synthesized fromSchiff-base by nitration. Compared with the method of direct nitration of benzaldehyde,this process has the following advantages:less iso-compound,simpler separation,better yield,higher product purity and superior economic benefit.
