人类的历史,就是一个不断地从必然王国向自由王国发展的历史,人类总是在不断地发展的,永远不会停留在一个水平上,因此人类总得不断地总结经验。我们在摸索处理石油醚的过程中,也要按照主席的教导,不断地进行总结,才能使我们在认识事物的客观规律中不断地前进。 石油醚的质量对族组份分析质量的影响非常大,族组份所需要的石油醚是纯饱和烃,既不能含有芳香烃,又不能含有有杂原子的烃(包括杂环,含氧、含氮、含硫化合物等)。若石油醚中含有上述杂质,会使族组份空白值增大,当石油醚中杂质超过一定量时,在族组份分析中淋洗饱和烃时必然会将芳香烃和非烃一起冲
Human history is a history of continuous development from a necessary kingdom to a free kingdom. Human beings are constantly developing and will never stay at one level. Therefore, mankind always has to sum up his experience. As we grope for the petroleum ether, we must continue to summarize according to the teaching of the chairman so that we can keep moving forward in the objective laws of knowing things. The quality of petroleum ether has a great impact on the quality of the components of the clan. The petroleum ether required by the clan is purely saturated hydrocarbons, which can not contain aromatic hydrocarbons nor heteroatoms (including heterocyclic, oxygen, Nitrogen, sulfur compounds, etc.). If the petroleum ether contains the above impurities, will make the blank value of the family component increases, when the petroleum ether impurities exceed a certain amount, in the analysis of the components of the composition of saturated saturated hydrocarbons inevitably will be aromatics and non-hydrocarbon together red
