실험 절차

133 g of o-tolylisocyanate and 5 g of solid, insoluble catalyst from Example 2a were heated to 140° C. with stirring. After evolution of 12.1 liters of carbon dioxide, which took place within 2 hours, the catalyst was suction filtered and the filtrate was distilled. 103.5 g of di-o-tolyl-carbodiimide, b.p. 130°-132° C./0.1 Torr were obtained (94% of the theory).
