| titleOfInvention | A kind of preparation method and device of isophorone |
| abstract | The invention provides a preparation method and device for isophorone, the method comprises the following steps: (1) reacting acetone with a weak acid and weak base catalyst to generate a small amount of aromatic compounds; (2) reacting the reaction of step (1) The product reacts under the condition of strong basic catalyst to generate isophorone. The device includes a fixed-bed reactor, a catalyst conveying device, a reactive rectification tower and a hydrolysis tower system. The system greatly overcomes the adverse effects of over-polymerization of acetone, and greatly improves the selectivity of acetone condensation reaction to generate isophorone. High purity and high selectivity. |
