Title: Process for production of MIBK using CD technology

Abstract: A process for producing methyl isobutyl ketone includes introducing acetone into a catalytic distillation. Some of the acetone is converted to mesityl oxide (`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 A product stream comprising MSO, water, and, optionally, DAA, other by-products and/or unreacted acetone is withdrawn from the catalytic distillation zone.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 product 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 A MIBK rich product stream is withdrawn from this reaction zone. Both a markup and clean copy of the substitute Abstract are attached to this amendment.
