催化剂、多环芳烃及硫对1-甲基萘以及二(1-萘)甲烷氢转移的影响

Effect of Catalyst, Polynuclear Aromatic Hydrocarbons, and Sulfur on Hydrogen Transfer to 1-Methylnaphthalene and Di(l-naphthyl)methane

探讨了在温和反应条件下,催化剂、多环芳烃及硫对金属催化剂催化的1-甲基萘(1-MN)以及二(1-萘)甲烷(DNM)加氢反应的影响。结果表明,铁和镍对促进1-MN和DNM的加氢非常有效,而多环芳烃却显著降低了1-MN和DNM的加氢转化率;加入硫显著阻碍了加氢反应,却大大促进了加氢裂解反应。初步探讨了有关的反应机理。

The effects of metallic catalysts (such as Fe, Ni), polynuclear aromatic hydrocarbons, and sulfur on the hydrogen transfer to l-methylnaphthalene(1-MN) and di(1-naphthyl)methane (DNM) under mild reaction condition were investigated. The results showed that catalysts can promote the hydrogen transfer to 1-MN and DNM, whereas polynuclear aromatic hydrocarbons and their partial hydrogenated products appreciably depressed the hydrogenation of 1-MN and DNM. The addition of sulfur depressed the hydrogenating reaction, but greatly promoted the hydrocracking reaction of DNM. The preliminary reaction mechanism was proposed to elucidate the phenomena.
