ABSTRACT:
Processes for producing higher molecular weight ketones are disclosed that include the steps of feeding an aldol catalyst solution, a lower molecular weight aldehyde, and a lower molecular weight ketone, through a reactor provided with a solid hydrogenation catalyst and hydrogen gas; recovering a liquid reactor effluent containing the higher molecular weight ketone as a reaction product; and recycling a portion of the recovered liquid reactor effluent back through the reactor.
