| In fact, as shown in Table 3, although the rate constant (k2) of the cis-to-trans isomerization reaction was higher than that of tetralin hydrogenation reaction (k1) the cis–trans isomerization on Pt and Ni catalysts was taken place when the concentration of tetralin on the surface was decreased . As discussed in previous study, the high adsorption constant of tetralin compared to that of decalin may be ascribed to the parallel adsorption of a more rigid aromatic-containing molecule than a bent naphthenic molecule |

實際上,如表3所示雖然順式到反式異構(gòu)化反應(yīng)速率常數(shù)k2大于四氫化萘加氫反應(yīng)速率k1,但是當四氫化萘的表面濃度降低時,Pt和Ni催化劑上卻可以發(fā)生順反異構(gòu)。之前的研究工作顯示,同十氫化萘相比,四氫化萘有更高的吸附常數(shù),可能歸因于彎曲構(gòu)型的環(huán)烷烴分子相比平整的芳烴分子缺少平行的吸附位 非信達雅 希望能幫到你 |
