Methyl Isobutyl Ketone → Toluene 2,4-Diisocyanate

Participants

Reaction Conditions

Reaction Steps

The half capped organic diisocyanate was charged into the reaction vessel and heated to about 66° C. under a blanket of nitrogen. Heating was stopped and the Imidazoline/propylene carbonate adduct was added slowly with the methyl isobutyl ketone. An exothermic reaction occurred and the temperature of the reaction mixture increased to 94° C. and then held at this temperature until all of the isocyanate was reacted which was determined by infrared analysis of the reaction mixture. The resulting reaction product had a solids content of 85.5%.
