Method for purification of pyridine, and method for production of chlorinated pyridine |
| abstract |
A method of purifying crude pyridine on an industrial scale at low cost and in a simple manner is provided. More specifically, a pyridine purification method including subjecting crude pyridine to an alkali treatment and then to distillation, or a pyridine purification method including adding an acid or water to crude pyridine, and subjecting the resulting mixture to an alkali treatment and then to distillation is provided. According to the purification method of the present invention, crude pyridine can be purified on an industrial scale at low cost and in a simple manner. Moreover, the pyridine purified by this method is useful as a starting material for various organic syntheses because of its high purity. For example, the pyridine can be reacted with chlorine to produce a chlorinated pyridine in a high yield. |
