摘　　要：近年来我国丙酮产量持续增长,丙酮产能逐渐过剩,与此同时,丙酮的高附加值利用相对较少;丙酮缩合制异佛尔酮,随后生产异佛尔酮二胺、异佛尔酮异氰酸酯等能够大大提高丙酮利用的附加值。本文对目前丙酮缩合制异佛尔酮的生产路线及催化剂研究进展进行了总结,重点介绍了有工业化应用的代表性工艺及催化剂,如以碱性氢氧化物为催化剂的丙酮液相缩合法以及以镁铝水滑石为催化剂的气相缩合法;在此基础上,进一步介绍了镁铝固体碱催化剂催化效果的影响因素,并对现有异佛尔酮合成工艺方法进行了分析、比较。最后对异佛尔酮的发展前景进行了展望。In recent years,the acetone production keeps growing,resulting in excess production capacity in China. On the other hand,high value-added applications of acetone are relatively limited. The process of making acetone self-condensation into isophorone,and subsequently into isophorone diamine,isophorone diisocyanate,can greatly enhance the added value of acetone. The paper reviewed the production routes of isophorone by acetone self-condensation and the research progress of the catalysts. We emphasized to introduce the representative industrial production processes and catalysts,such as acetone liquid phase condensation with alkaline hydroxide as catalyst and acetone gas condensation with hydrotalcite as catalyst. Then,we further discussed the factors influencing the catalytic performance of Mg-Al solid base,and compared the advantages and disadvantages of the production routes of isophorone. Finally,the prospects of isophorone is forecasted.
