Purification of Chlorophenol Isomers by Stripping Crystallization Combining Melt Crystallization and Vaporization

Stripping crystallization (SC) was introduced in this work to purify p-chlorophenol from the p-chlorophenol-rich liquid mixture and to purify m-chlorophenol from the m-chlorophenol-rich liquid mixture, respectively. Essentia...
