Title

Solution Kinetics of the Water-toluene Diisocyanate Reaction

Abstract

The water-isocyanate reaction is important in the production of polyurethane-polyurea foams and films. The kinetics and progress of this reaction were investigated by monitoring the evolution of carbon dioxide, the depletion of water, and the depletion of isocyanate. All investigations were conducted at 25 C in diglyme to permit a single phase system for the duration of the reaction. A difunctional isocyanate rather than a monofunctional isocyanate was used to better simulate most industrial systems which generate polyureas. Reaction profiles showing reactants, intermediates, and products are presented for the catalyst investigated.
