3-苯氧基苯甲醛的合成工艺

Synthesis of 3 Phenoxybenzaldehyde

以３－苯氧基甲苯为原料，在紫外光照射下进行侧链氯化转化成３－苯氧基－α，α－二氯甲基苯，经硫酸－醋酸水解得高纯度的３－苯氧基苯甲醛，总收率８０％～８５％。

Phenoxybenzaldehyde,a key intermiediate for preparation of pyrethroid pesticides,was synthesized from 3 phenoxytoluene via 3 phenoxybenzal chloride,by chain chlorination followed by hydrolysis with 80%～85% overall yield.
