| titleOfInvention | Acetonitrile purification method |
| abstract | After adding alkali to acetonitrile containing water produced by an ammoxidation reaction, the reaction mixture was supplied to the first distillation column, and the resulting distillate was further mixed with alkali to form an acetonitrile phase. A method for purifying acetonitrile comprising the steps of: separating the aqueous phase and then removing the aqueous phase and supplying the acetonitrile phase to a second distillation column, wherein the distilled vapor from the second distillation column is A method for purifying acetonitrile as a heat source for the reboiler of the first distillation column. |
