Effect of Catalysts on the Kinetics of the Water-toluene Diisocyanate Reaction
The water-isocyanate reaction is important in the production of polyurethane-polyurea foams and films. This reaction is usually investigated with emphasis upon the kinetics of foam formation or film curing and the final properties of the polymer product. The reaction involves a carbamic acid intermediate which decomposes into carbon dioxide and an amine which may further react with isocyanate. This paper describes the evolution of carbon dioxide from the reaction of the diisocyanate with water conducted in an organic solvent under a variety of conditions and catalytic influences.
