Embodiment 1
[0021] Put 1000Kg of acetone as raw material, 100Kg of NaOH aqueous solution containing 3 Kg of catalyst, 0.2 Kg of auxiliary catalyst magnesium oxide, aluminum oxide, calcium oxide, barium oxide, and lanthanum rare metal element into the autoclave, heat to 130°C, and rotate at 250 rpm. The reaction was continuously stirred at constant temperature for 2 hours, then cooled to 80°C, and the unreacted acetone was distilled and cooled to reflux for next use. After the root of the kettle is static, the liquid is separated, and the catalyst aqueous solution is released for use next time, and the remaining product is distilled under reduced pressure to obtain the finished product by distilling the isophorone.
