化学师用化学的方法造成与天然物完全一样的东西,并且比天然物纯洁而价廉,这是谁都知道的事情。究竟他们用什么方法完成这个惊人的工作呢?一、他们先从天然物中提出极纯粹的东西。二、分析其成分,而查察这些原素是以怎样的比例相结合的。三、更行亚佛加特罗(Avogadro)的分子量决定法定出分子式(molecular formulas)。四、次更用合成方法阐明构造式(structural formula)。五、构造式阐明之后,从便宜的原料中照样配合,于是制成同天然品一样的东西。
Chemists use chemical methods to make exactly the same thing as natural things, and they are cleaner and cheaper than natural ones. After all, what methods do they accomplish this amazing job? First, they put forward extremely pure things from the natural world. Second, analyze its composition, and investigate what is the proportion of these elements combined. Third, make Avogadro’s molecular weight decision legal molecular formula (molecular formulas). Fourth, times more use of synthetic methods to clarify the structural formula (structural formula). Fifth, the elucidation of the structural formula, the same from the cheaper raw materials, so made with the same natural products.
