对溴苯甲醛合成新方法的研究

New Synthetic Method of P-bromobenzaldehyde

本文用三氧化二锰作为氧化剂,以对溴甲苯为原料,在不同条件下进行反应合成对溴苯甲醛,探讨了酸度、温度、三氧化二锰用量等因素对对溴苯甲醛产率的影响。结果显示,该方法具有反应条件温和,产率高,工艺简单,无污染等特点,易于实现工业化生产。

P - bromobenzaldehyde was prepared from p - bromotoluene by manganese sesquioxide oxidation. Various factors affecting the yields of p-bromobenzaldehyde, such as concentration of surphric acid, temperature, weight of manganese sesquioxide have been studied. The result shows that in this new synthetic route, the yield is high, the quality of product is good and operations are simple.
