二十烷 ,菲作为模型化合物 ,以四氢萘为供氢剂 ,在临氮及临氢体系中应用氘代四氢萘考察供氢剂的氢转移反应 ,发现供氢剂抑制烷烃的裂化 ,其作用是通过脱氢湮灭自由基来抑制裂化反应。临氮及临氢条件下 ,与正二十烷与菲的二元体系相比 ,正二十烷、菲和四氢萘三元体系中四氢萘不仅能生成较多的菲的氢化芳烃产物 ,而且稳定同位素方法表明氘代四氢萘可以向菲和菲的氢化芳烃产物转移更多的氘。同时发现H1 2 四氢萘和D1 2 四氢萘的供氢 (氘 )率上存在着动力学同位素效应。
Eicosane and phenanthrene as model compounds and tetrahydronaphthalene as hydrogen donating agent. Hydrogen transfer reaction of hydrogen donor was investigated using deuterated tetrahydronaphthalene in nitrogen and hydrogen system. Hydrogen donor was found to inhibit the cracking of alkane, Its role is through the dehydrogenation of free radicals to suppress the cracking reaction. In the presence of nitrogen and hydrogen, tetralin in n-eicosane, phenanthrene and tetrahydronaphthalene ternary system can not only generate more phenanthrene hydrogenated aromatic products than n-eicosane and phenanthrene binary system , And the stable isotope method shows that deuterated tetrahydronaphthalene can transfer more deuterium to the hydrofluorinated products of phenanthrene and phenanthrene. It is also found that there is a kinetic isotope effect on the hydrogen (deuterium) rate of H1 2 tetralin and D1 2 tetralin.
