We have, therefore, in both of the examples above, heterocyclic compounds with "built-in" or latent functionality . 上述两例中的杂环化合物,都具有“固有的”或潜在的官能基。
The oh functionality of the polyether may be controlled by using modifiers such as glycidol, ethylene glycol, water or trimethylol propane . 用缩水甘油、乙二醇,水或三羟甲基丙烷等改良剂,可控制聚醚的羟基官能团。
