三氟化硼-苯甲醚络合物的解离方法研究

Research of boron trifluoride-benzene methyl ether complex dissociation method

对三氟化硼-苯甲醚络合物体系的解离条件进行了研究,考察了温度、压力和助剂DCM对络合物解离的影响。随着温度的升高,络合物的络合度逐渐降低;压力升高,络合物的解离温度、杂质含量也相应升高。助剂DCM的加入可以破坏原有络合平衡,降低解离所需温度,并有效减少苯酚等杂质的生成。

The decomposition condition of BF3-anisole complex system was studied.The effect of temperature,pressure and the auxiliary(dichloromethane)were investigated.With the increase of temperature,complexing degree of the complex was gradually reduced;temperature and the impurity content of the complex were also increased according to the increase of the pressure.The addition of DCM can destroy original complexing balance,lower the temperature needed to decomposition,and reduce the generation of impurities such as phenol effectively.
