| Abstract: | The phenol made from cumene is a method used widely,there are a variety of organic impurities, which affects the stability of the color of phenol,generating in the process.The impurities are difficult to be removed by general distillation.The phenol purified by process commercialized can make the quality to meet the requirements in its downstream.Based on the problems of impurities in the purified process,the finished phenol analyzed,it has been proved that the phenomenon of azeotropy appears between 2-meth... |
