Abstract

The invention relates to a process comprising: reacting isobutyraldehyde with an aqueous solution of urea in the presence of a phase transfer catalyst to form isobutylidene diurea. Preferably the phase transfer catalyst is a quaternary ammonium salt more preferably benzyltriethylammonium chloride. Even more preferably the process is performed in one pot.
