邻硝基苯甲醛的制备

Preparation of o-nitrobenzalcdhyde

本文叙述了一种以邻硝基甲苯为原料，经特殊的侧链光溴代工艺制备邻硝基亚苄二溴，并经相转移催化水解合成邻硝基苯甲醛的新方法．通过对反应的研究证明这是一种收率高、成本低、三废少、有工业化价值的合成方法．

A Process for the preparation of o-nitrobenzaledhyde where in after a peculiar side chain bromisation of o-nitrotoluene, benzal bromide has been phase transfer catalytic hydrolysised. By studying of reaction, it has been testified that this is a commercial synthetic method of high yield, low cast and small industrial waste.
