中低温煤焦油重油正庚烷萃余物的反应(甲醛)分离与分析
Reaction ( formaldehyde) separation and analysis of n-heptane extraction residue from heavy oil of medium and low temperature coal tar
摘要
Abstract
The n-heptane extraction residue ( H-CT) from heavy medium and low temperature coal tar made in northern Shaanxi by n-heptane was reacted with formaldehyde. The product ( P) was divided into n-heptane soluble ( HS-P ) , n-heptane insoluble but toluene soluble ( HI-TS-P ) , toluene insoluble but quinoline soluble ( TI-QS-P) and quinoline insoluble ( QI-P) . The structure and composition of P were analyzed by means of GC-MS, TG-FTIR and FT-IR. The results show that P has more contents of TI-QS-P, oxygen atoms and a higher C/H atom ratio comparing with H-CT. The contents of HS-P, HI-TS-P, TI-QS-P and QI-P are 11. 63％, 26. 42％, 57. 08％ and 4. 88％, respectively. HS-P and HI-TS-P contain mainly neutral components ( mainly aromatics) , few acidic components ( mainly phenols) , and some heteroatom compounds including O, N, S. TI-QS-P, with highly thermal stability, is rich in carbonyl groups, methylene bridge bonds and fused ring aromatic compounds. Besides, it also contains phenolic hydroxyl groups and aromatic ring substitutes.关键词
