【摘要】 研究三种异氰酸酯与双（三正丁基）氧化锡在等摩尔比时的反应。证明相互作用的产物是以缔合形式存在的相应锡的氨基甲酸酯。双（三正丁基）氧化锡碳酸酯，氨基甲酸酯及其在异氰酸酯环三聚反应中水解产物催化活性的研究，证明氨基甲酸酯或它与异氰酸酯相互作用的产物，在双（三正丁基）氧化锡参加下，对三聚过程的催化起决定作用。更多还原

【Abstract】 The reaction of three isocyanates with bis(tri n butyltin) oxide in equimolar ratio was investigated.Tin carbamates,existing as associates,were shown to be the products of this interaction.The catalytic activity of bis (tri n butyltin) oxide carbonate,carbamate and their hydrolytic products were studied in the trimerization of isocyanates.The carbamate and the products of its interaction with isocyanate were shown to be responsible for the catalysis of trimerization in the presense of bis (tri n butyltin) oxide.更多还原
