两种亮煤用CS2-NMP溶剂抽提后的结果分析

ANALYSIS ON THE RESULTS OF TWO CLARAINS EXTRACTED BY MIXED SOLVENT OF CS_2-NMP

研究了童亭亮煤和洼里亮煤在CS2 - NMP混合溶剂中的可溶性,重点考察了原煤,萃取物,萃余物在工业分析、真密度和黏结指数方面的联系;同时运用红外光谱( FTIR)现代分析技术对原煤及其萃取物和萃余物的组成和结构特征进行了对比分析,在此基础上提出了煤中主要存在两种组分即“致黏组分”和“不黏组分”的概念,并据此对胶质体液相的来源作了初步解释.最后得出了萃取物中主要是煤中富含脂肪族和酚,醇,醚结构的组分,而萃余物中主要是富含缩合芳环的组分.

This thesis investigates the solubilities of Tongting clarain and Wali clarain in CS_2-N-methy1-2-pyrolidinone mixed solvent.Mainly examines the inherent relationships between raw coal,exacts and residues at the industrial analytic,real density and viscosity;comparative analysis for the components and structural characterizations of raw coal,exacts and residues by applying advanced analytic techniques such as FTIR.Based on the researches mentioned above,the conclusion is drawed,that extracts contains aliphatic in coal and components having the structural of alcohol,phenolic,ether,but residues contains the components having the structural of aromatic.
