Hydroformylation reaction processes

A hydroformylation reaction process, the process comprising:

• (a) contacting an olefin, hydrogen, and carbon monoxide in the presence of a homogeneous catalyst in a reactor to provide a reaction fluid, wherein the reactor comprises one or more reaction zones;
• (b) removing a portion of the reaction fluid from a first reaction zone;
• (c) passing at least a portion of the removed reaction fluid through a shear mixing apparatus to produce bubbles in the portion of the removed reaction fluid, wherein at least a portion of hydrogen and carbon monoxide provided to the reactor is introduced through the shear mixing apparatus;
• and
• (d) returning the removed reaction fluid to the first reaction zone through one or more nozzles wherein the returning reaction fluid exiting each nozzle is a jet, wherein the mixing energy density provided to the reactor by the jets meets the following formula:
