The higher selectivity to isopentenes, however, was regarded as a consequence of both insufficient active sites for further hydrogenation of isopentenes to isopentane and lower electronic interaction between Pd and the alumina surface.

而较高的选择性则可归因於没有足够的钯活性中心可供异戊烯进一步氢化生成异戊烷以及钯金属和氧化铝间较低的电子效应所致。

Sciaenops ocellatus has the fishy, specific grassy, fatty and melon-like odor. Hexanal and1-Penten-3-ol contribute to the form of fishy smell most greatly, also the environment and the cooperative or accumulative effects of other volatile compounds have certain impacts. Compared with the dorsal muscle, the abdominal muscle is fishier (F0.01). 1-Octen-3-ol, 4-Heptenal and benzaldehyde have close relations to the form of characteristic flavor.
