| titleOfInvention | Method for preparing tertiary butanol by using hydration of isobutene in mixed C4 |
| abstract | The invention relates to the field of chemical industry and in particular relates to a method for preparing tertiary butanol by using hydration of isobutene in mixed C4. By adopting a catalytic distillation tower, the technical process is simplified, so that the equipment and operation costs can be reduced; the mixed C4 and deionized water enter the tower by using a reverse flowing manner; the concentration difference of the gas phase and the liquid phase is improved; the product tertiary butanol is continuously discharged out of the tower; the reaction is accelerated to progress in the positive direction; the reaction balance limit is broken, so that the conversion rate of isobutylene is increased. In addition, the deionized water is directly charged into the top of the tower and is used for sucking tertiary butanol in the residual gas; the conversion rate of isobutylene is increased; the top of the tower is free of reflux; the energy consumption is reduced; the reflux of the isobutene is avoided, so that the generation of by-products comprising polymers and C8 ether are reduced; the selectivity of isobutylene is improved; the reaction temperature is easy to control; the heat accumulation in a catalyst layer is avoided; the generation of the polymers is reduced; the selectivity of isobutylene is improved. The conversion rate of the isobutylene is greater than 90%; the selectivity is greater than 99%; the method is suitable for industrial production. |
