【摘要】 讨论了溶剂、温度、催化剂对苯酚单封端异氰酸酯反应的影响。结果表明 :极性溶剂参与了反应而非极性溶剂只起分散作用。催化剂可以有效地加速反应的进行。此外温度也是反应的函数更多还原

【Abstract】 In this paper, effects of solvent, catalyst and temperature on the reaction of diisocyanate monoblocked by phenol were examined. It was found that polar solvent may actively participate the blocking reaction while nonpolar one only played a dispersion role. Catalyst remarkably accelarated the reaction rate. In addition, temperature is function of this reaction.更多还原
