| 摘 要： | 通过甲醇用量、回流时间和硝酸浓度对催化剂活性的影响进行了讨论，研究了非那甾胺合成工艺中孕烯醇酮氢化Pd/C催化剂的再生方法。实验发现，对于1 g废Pd/C催化剂，以30 mL甲醇为萃取剂，回流萃取60 min，然后用35%的硝酸在80 ℃氧化30 min，可以达到满意的再生效果，新鲜和再生的Pd/C催化剂孕烯醇酮的氢化转化率分别为97.5%和98.5%。

| Abstract: | Regeneration of Pd/C finasteride synthesis catalyst by extraction-oxidation was studied, including the influence of methanol amount, reflux time and nitric acid concentration. Pregnendone conversion of 97.5% was attained after the Pd/C catalyst was treated under following condition: extracting 1 g used Pd/C catalyst with 30 mL methanol at boiling point for 60 min and then oxidating the Pd/C catalyst with 35% nitric acid at 80 ℃ for 30 min. |

| Keywords: | oxidation-extraction method regeneration finasteride Pd/C catalyst |
