Analysis of pyrolysis liquids obtained from the slow pyrolysis of a German brown coal by comprehensive gas chromatography mass spectrometry was written by Rathsack, Philipp. And the article was included in Fuel in 2017.Product Details of 638-02-8 The following contents are mentioned in the article:
Due to the upcoming shortage of crude oil and natural gas, alternative resources for the production of chems. are needed and long-term research should be conducted. One of the future possible methods for the production of valuable chems. is the use of coal and its conversion by pyrolysis. During pyrolysis, macromol. organic compounds are decomposed into smaller compounds, which can be used. The development of these processes requires compositional knowledge of the products, which are very complex mixtures of organic compounds Pyrolysis liquids obtained in a fixed bed reactor at different pyrolysis temperatures between 400 and 700° is analyzed qual. and quant. by comprehensive gas chromatog. mass spectrometry (GC×GC-MS). More than thousand compounds were observed in each of the samples. Selected compound classes (alkanes, alkenes, alkylbenzenes, phenols, carboxylic acids and thiophenes) are discussed. Quantification results of 94 compounds are given, visualized and discussed in relation to the pyrolysis conditions. It is demonstrated, that the application of GC×GC-MS is highly beneficial for the anal. of pyrolysis liquids from coal. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Product Details of 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The core structure is a part of various pharmaceutical substances and natural products. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Product Details of 638-02-8
