| Abstract: | Principle and character of the bubbling crystallization method was studied in this paper.The paradichlorobenzene is separated from the by-produ ct of chlorobenzene,the mixture of dichlorobenzene by this method. The purity of the paradichlorobenzene is more than 99.5%,The number of separation step and the operative conditions of each step were also determined. |
