摘要：

The effect of Sn concentration in PtSn/Al2O3 catalysts prepared by different procedures on the catalytic behavior in the carvone hydrogenation in liquid phase was studied. Results indicated that the increase of the Sn amount added to Pt modified the catalytic behavior, favoring the formation of unsaturated ketones and the simultaneous production of small quantities of unsaturated alcohols as reaction intermediaries. On the other hand, Pt/Al2O3 catalyst only produced carvomenthone as the main reaction intermediary. (C) 1999 Elsevier Science B.V. All rights reserved.
