Abstract:
A φ24 mm distillation column was established to separate 2-Chloro-3-methylpyridine and 2- chloro- 5-methylpyridine from mother liquor by extractive distillation. The purity of both products was over 95%( wt. ) . The results show that the recovered extractant can be reused. The main operational parameters in the extractive distillation process is also disussed.
