摘要
在一项针对异佛尔酮二异氰酸酯(IPDI)于氨基甲酸酯反应中的选择性之模型研究中,提示了催化剂类型和温度的影响。同时通过选择伯丁醇和仲丁醇作为反应对象,介绍了羟基类型的影响。 需特别指出的是,催化剂的选择对最终产品的组成有着极重大的影响。模型研究的最重要结论在NCO预聚物的合成中得到了肯定。
In a model study for the reactivity of two isocyanate groups of isophorone diisocyanate, it reveals the influence of temperature and catalyst in urethane reaction. Using primary and secondary butanol as coreagent the article decribes the influence on type of hydroxy group. It is emphasized that the selection of catalyst has great influence on the composition of final product. In NCO prepolymer synthesis the most important conclusion of this model study is confirmed.
