双语例句
- Iso-butene and methanol etherification proceeds according to the electrophilic addition mechanism, Iso-butene makes protonation reaction as the proton acceptor under the acid catalyst function, being born the positive carbon ion, intermediate products react rapidly with nucleophilic reagent ( CH3O-) to produce MTBE.
异丁烯在酸性催化剂作用下作为质子的接受体发生质子化反应，生成正碳离子；作为中间产物的正碳离子，再迅速同亲核试剂CH3O-反应，生成MTBE。
