3-溴-4-羟基苯甲醛的制备

Synthesis of 3 - Bromo - 4 - hydroxybenzaldehyde

以工业对羟基苯甲醛和溴素为原料,CHCl3为溶剂高收率地制备了一溴醛。一溴醛收率94.5％, 二溴醛收率5.5％,溶剂CHCl3之回收率为98％。

Using p - hydroxybenzaldehyde and bromine as materials and CHCl3 as solvent, the high yield of reaction in synthesis of 3 -bromo - 4 - hydmxybenzaldehyde has been obtained. The yield of 3 - bromo - 4 - hydroxybenzaldehyde was 94.5% and 3.5- dibromo - 4 - hydroxybenzaldehyde was 5.5%. The rate of recovery of CHCl3 was 98% .
