| Abstract: | Extractive acid used as the continuous phase, the separation of m-chloroanilme and p-chloroanilme is carried out by continuous countercurrent dissociation extraction in a filling power equipment. We compared the effection of different filling, remain time and height of filling. We also separated a mixture of m-and p-chloroaniline. The purity of m-chloroaniline is higher than 99%. |
