| titleOfInvention | Method for preparing isophorone by acetone liquid condensation with alkali catalyst |
| abstract | The invention discloses a method for preparing isophorone by acetone liquid condensation with an alkali catalyst. The method comprises steps of: heating an aqueous solution of acetone and the alkali catalyst to 230-280 DEG C under continuous stable operation conditions; controlling the pressure to maintain the acetone and water in liquid phase state; then introducing the two together through a mixer and a micro channel reactor with a total staying time of 3-15 min; carrying out a condensation reaction on the acetone with catalysis effect of the alkali catalyst to generate isophorone; and sending the reaction products into a reaction rectifying tower, removing unreacted acetone and hydrolyzing high boiling products with carbon atom number higher than 12, so as to obtain the isophorone crude product in a column bottom. A acetone one-way conversion rate exceeds 20%, and isophorone effective selectivity reaches higher than 90%. The method of the invention generates good mass transfer and heat transfer effects and has accurately controlled reaction time, high one-way conversion rate and good effective selectivity. |
