能量表明,当反应发生之后,你最终会得到放热的产物,换句话说就是产物比反应物更稳定。
Energy means, you know, chemical reactions happen, and you end up with something that might be exothermic, that is, the products are more stable then the reactants.
反应产物经过分离、提纯等进一步物理处理工艺以获得期望的最终产品。
The products of the reactions must then undergo further physical treatment-separations, purifications, etc-for the final desired product to be obtained.
采用活泼二卤代烷与一种长链叔胺经过一步反应得到最终产物,产率较高。
Active saturated dihalide is adopted to further react with long chain tertiary amine to obtain a final product with high yield.
Energy means, you know, chemical reactions happen, and you end up with something that might be exothermic, that is, the products are more stable then the reactants.
