Li, Qian; Duan, Zheng-kang; Luo, He-an; Yao, Yuan-yuan published an article in 2016, the title of the article was Analysis of solvent extracts from coal with gas chromatography-mass spectrometry.Related Products of 34413-35-9 And the article contains the following content:
Shanxi coal was extracted with acetone, DMF, cholamine and ethylenediamine by soxhlet extraction and stirring extraction, resp. With ethylenediamine as the solvent and using simple stirring extraction, the extraction yield was up to 17.1%. A gas chromatog.-mass spectrometry (GC/MS) method for determination of ethylenediamine extracts and cholamine extracts was developed. The results showed that 53 organic species were identified from the ethylenediamine extracts, and they can be classified into four groups components: arenes, aliphatic hydrocarbons, nitrogen compounds and oxygen compounds The nitrogen compounds are the most abundant compounds of which relative contents of area normalization is 75.64%. Compared with the detected species of ethylenediamine extracts, the detected species of cholamine extract is less, and the components of cholamine extract are different from that of ethylenediamine extract The experimental process involved the reaction of 5,6,7,8-Tetrahydroquinoxaline(cas: 34413-35-9).Related Products of 34413-35-9
