| titleOfInvention | A kind of preparation method of butanol |
| abstract | The invention discloses a method for preparing high-purity butanol. In the preparation method, the purity of butanol is increased to more than 99.5% by purifying the crude butanol aqueous solution with an ion exchange resin, and then mixing a solvent for recrystallization and purification. The operation is simple, the requirement for equipment is relatively low, the preparation time is short, the cost is low, the control is easy, and it is suitable for scale-up production in large-scale chemical factories. |
