실험 절차
133 g of o-tolylisocyanate and 5 g of solid, insoluble catalyst from Example 1a were heated together to 180° C. with stirring. After the evolution of 12.3 liters of carbon dioxide, which took place within 1.5 hours, the catalyst was suction filtered and the filtrate distilled. 95.3 g of di-o-tolyl-carbodiimide, b.p. 135°-137° C./0.1 Torr were obtained (87% of the theory).
