TLDR
In this article, a process for the production of methyl isobutyl ketone from acetone and hydrogen utilizing a catalytic distillation column reactor is described, where reactions take place in a reaction zone with the reaction products being removed from the reaction zone and unreacted acetone being refluxed.Abstract:
A process for the production of methyl isobutyl ketone from acetone and hydrogen utilizing a catalytic distillation column reactor. The reactions take place in a reaction zone with the reaction products being removed from the reaction zone and unreacted acetone being refluxed. The equilibrium is thus continuously disturbed allowing for greater than equilibrium conversion of acetone.read more
