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 A product stream comprising MSO, water, and, optionally, DAA, other by-products and/or unreacted acetone is withdrawn from the catalytic distillation zone.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 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 A MIBK rich product stream is withdrawn from this reaction zone.
