摘要
以氯仿为溶剂直接溴化制备对溴苯酚 ,在工艺上减少了减压蒸馏步骤 ,避免了对溴苯酚在高温下发生岐化异构化反应 ,结果纯度达到 99.7%以上 ,收率为 91%。
Para-bromophenol was synthesized with purity of 99.7 % and yield of 91 % by selecting composite chloreform as solvent. Based on property of para-bromophenol, the procedure of the distillation under vacuum was omitted and the disproportionation reaction of para-bromophenol was avoided under the high temperature.
