Abstract:
Components extracted from coals contained a lot of monomers , which can be synthesized into many kinds of important and valuable polymers. Nantong bituminous and Yunnan lignite are extracted with carbon disulfide-N-methyl- 2-pyrrolidinone (CS2-NMP) mixed solvent and Acetone at room temperature in turn. The Acetone soluble fractions are analyzed by GC/MS. Experimental results demonstrate that the Acetone soluble fractions mainly consist of aliphatic hydrocarbons, aromatic hydrocarbons, nitrogen-containing compounds and oxygen-containing derivatives. Nitrogen-containing compounds mainly consist of cholesterin, oxygen-containing derivatives mainly consisted of ester and hydroxybenzene,etc.However, sulfur-containing compounds, phosphorus-containing compounds and polycyclic aromatic compounds can not be detected. Moreover, hexadecanoic acid trimethylsilyl ester and Hexadecanoic acid, trimethylsilyl ester are tested in Nantong coal's Acetone soluble fraction.
