    Abstract: A catalytic process for producing isocyanurate compounds from isocyanates is disclosed. The catalyst is N-(2-hydroxyethyl)ethyleneimine. The isocyanate can be a monoisocyanate, a polyisocyanate or a polymeric isocyanate. The isocyanurates are known compounds having known uses. The foamed isocyanurate polymers have the same utilities known for the foamed urethane polymers.

    Abstract translation: 公开了从异氰酸酯制备异氰脲酸酯化合物的催化方法。 催化剂是N-(2-羟乙基) - 乙烯亚胺。 异氰酸酯可以是单异氰酸酯,多异氰酸酯或聚合异氰酸酯。 异氰脲酸酯是具有已知用途的已知化合物。 发泡异氰脲酸酯聚合物具有与发泡聚氨酯聚合物相同的用途。
