摘　　要：为解决工业废水中溴化氢污染环境问题,有效回收稀缺资源溴素,采用氧化铜和溴化亚铜为溴素回收剂合成溴化铜,再以溴化铜为溴源合成四溴双酚A。在摩尔比n(双酚A)∶n(CuBr_(2))=1∶9、温度20℃下溴化2 h,再升温到70℃溴化3 h,合成四溴双酚A收率97.43%。通过反应动力学计算,得出以溴化铜溴代双酚A合成四溴双酚A为一级反应,反应活化能为27.73 kJ/mol,并且进一步得出反应后期升温有利于三溴双酚A冲破能垒向四溴双酚A转化。In order to solve the problem of environmental pollution caused by hydrogen bromide in industrial wastewater and effectively recover scarce resource bromine,copper oxide and cuprous bromide were used as bromine recovery agents to synthesize copper bromide,and then TBBPA was synthesized with copper bromide as bromine source.The yield of TBBPA was 97.43%when n(BPA)∶n(CuBr_(2))=1∶9,brominated at 20℃for 2 hours and then brominated at 70℃for 3 hours.Through the calculation of reaction kinetics,it is found that the synthesis of TBBPA from BPA by copper bromide is a first-order reaction,and the reaction activation energy is 27.73 kJ/mol.Furthermore,increasing the temperature in the late stage of the reaction is beneficial to the conversion of tribromobisphenol A to tetrabromobisphenol A.
