GC/MS analysis of ethanolysis product from Zhaotong lignite
Abstract:Ethanolysis of Zhaotong lignite was conducted at 230-350 ℃. The highest yield of 64.9% was obtained at 305 ℃. The resulting ethanol-soluble portion was analyzed with a GC/MS. In total, 100 organic compounds were detected and they can be classified into alkanes, arenes, phenols, alcohols, methoxyarenes, ethyl esters, aldehydes, ketones, ethers, nitrogen-containing species, sulfur-containing species, and other compounds. Among them, the most abundant compounds are ethyl esters and followed by alcohols and phenols.
Keywords: lignite ethanolysis GC/MS analysis
