    • A process for producing methyl isobutyl ketone includes introducing acetone into a catalytic distillation. Some of the acetone is converted to mesityl alcohol ('MSO'), water and, optionally, diacetone alcohol ('DAA') and/or other by-products. A product stream comprising MSO, water, and, optionally, DAA, other by-products and/or unreacted acetone is withdrawn from the catalytic distillation zone. When the product stream includes DAA, other by-products and/or unreacted acetone, it is treated in a treatment zone to remove at least some of the DAA, other by-products and/or the unreacted acetone therefrom. The products stream and hydrogen are fed into a reaction zone in which MSO present in the product stream and hydrogen react to form methyl isobutyl ketone ('MIBK'). A MIBK rich product stream is withdrawn from this reaction zone.
    • 一种生产甲基异丁基酮的方法包括将丙酮引入催化蒸馏。 一些丙酮被转化为均三甲醇(“MSO”),水和任选的双丙酮醇(“DAA”)和/或其它副产物。 从催化蒸馏区取出包含MSO,水和任选的DAA,其它副产物和/或未反应的丙酮的产物流。 当产物流包含DAA,其它副产物和/或未反应的丙酮时,在处理区中处理至少一些DAA,其他副产物和/或未反应的丙酮。 将产物流和氢气进料到产物流中存在MSO的反应区,氢反应形成甲基异丁基酮(“MIBK”)。 从该反应区中取出富含MIBK的产物流。

    • A method for the catalytic manufacture of MIBK and DIBK from DMK and/or IPA (optionally in the presence of water) while obtaining improved control over the ratio of DIBK to MIBK in the product stream, comprising reacting, in the presence of an aldol condensation catalyst, a reactant mixture comprising DMK and/or IPA and an effective amount of an additional reactant selected from the group consisting of mesityl oxide (MSO) and methyl isobutyl carbinol (MIBC) and mixtures thereof. Reaction temperature may also be changed to affect the product ratio obtained. The preferred catalyst is copper-based. An overall excess of hydrogen is desired, and this may be achieved by introducing or recycling hydrogen, and/or by balancing exothermic and endothermic reactions. By this invention, the product ratio of DIBK to MIBK is altered such that, as DMK and/or IPA conversion is increased, a lesser amount of DIBK than normal is produced, resulting in improved ability to control the product ratio of these materials.
    • 一种从DMK和/或IPA(任选地在水存在下)催化制备MIBK和DIBK的方法,同时获得对产物流中DIBK与MIBK比例的改进控制,包括在醛醇缩合物 催化剂,包含DMK和/或IPA的反应物混合物和有效量的选自意大利氧化物(MSO)和甲基异丁基甲醇(MIBC)的其它反应物及其混合物。 也可以改变反应温度以影响获得的产物比例。 优选的催化剂是铜基。 需要全部过量的氢气,并且这可以通过引入或循环氢气和/或通过平衡放热和吸热反应来实现。 通过本发明,改变了DIBK与MIBK的产物比例,使得当DMK和/或IPA转化率增加时,产生比正常量少的DIBK,从而提高了控制这些材料的产物比例的能力。
