PROCESS FOR THE PREPARATION OF ISOBUTYLIDENE DIUREA

摘要

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.
