It is found that Brij-35 is the most efficient surfactant forsolubilization of C60 and the possible states of C60 existed in surfactants are also studied.Experiments of surface tension show that the sites for solubilization of C60 not only depend on thesorts of surfactants but also on their structures.展开更多

In this paper, with 1-bromocyclohexane (1-BrCH) as an external heavy atom perturber, 7,8-benzoquinoline (7,8-BQ) was used as a model compound, hydrogen and carbon dioxide are used for deoxygenation in CD-RTP and compared with two traditional deoxygenation techniques. The results show that the new deoxygenation techniques have obvious advantages such as simpler facilities, faster speed of deoxygenation and wider acidity range etc.展开更多
