Efficient gas-phase bromination of 1, 1, 1, 2-tetrafluoroethane (HFC-134a) for the preparation of 1, 1-dibromo-1, 2, 2, 2-tetrafluoroethane (CF3CFBr2) has been described for the first time. A wide-ranging experimental investigation on the influence of some relevant process parameters was performed with the use of optimized parameters, resulting in the HFC-134a conversion yield and the selectivity to
已经描述了用于制备1、1-二溴-1、2、2、2-2-四氟乙烷(CF 3 CFBr 2)的1、1、1、1、2-四氟乙烷(HFC-134a)的高效气相溴化。第一次。使用优化的参数对一些相关工艺参数的影响进行了广泛的实验研究,结果得出HFC-134a的转化率和对CF 3 CFBr 2的选择性分别高于98%和60%。此外,通过最新的密度泛函理论计算确定了可能的反应途径和产物。HFC-134a的气相溴化提供了一种生产CF 3 CFBr 2的潜在方法 在当前相关行业领域。
