Study on Separating Mixed Dichlorophenol by Cross-Current Dissociation Extraction
Based on the detailed analysis on the properties of each component in the system of dichlorophenol mixture in this paper, a new technique was proposed, which is used to extract 2,4- dichlorophenol through the method of cross-current dissociation extraction. The experimental results show that the quality content of 2,4- dichlorophenol can be refined to more than 98% with the yield reaching to 95% at a blow from raw material mixture after three grades of dissociation extraction. Compared with the traditional technique, the new method can bring about a comparatively simple processing step, meanwhile, the quality of products can be stable and the energy consumption can also be reduced.
