35.石炭および石油重質溶媒可溶成分の溶解度に及ぼす添加物効果

抄録

The addition of some organic and inorganic compounds such as TCNE and LiCl has been found to be effective for the increase in extraction yields of coals and solubility of coal-derived ultra-heavy component, i.e., pyridine insoluble, CS_2/NMP soluble materials at our laboratory. The addition of basic compounds such as riethylamine were also reported to increase coal extraction yields. While, solubility of petroleum asphaltenes in alkanes increases by the addition of amphiphiles such as p-(n-dodecyl) benzenesulfonic acids. The mechanisms for solubilization are discussed.
