| 摘 要： | 以氧化改性活性炭为载体,用浸渍法制备了系列VOSO4/活性炭催化剂(VO/ACO).采用FT-IR、XRD、ICP和比表面及孔结构测定等表征了催化剂组成与结构.考察了VO/ACO催化剂在常压分子氧氧化乳酸乙酯中的催化作用.结果表明,氧化活性炭是氧钒催化剂的有效载体,以pH=3的VOSO4溶液浸渍得到的VO-3/ACO催化剂具有优良的催化性能,在二氯乙烷中常压,80℃反应18 h,乳酸乙酯转化完全,丙酮酸乙酯的选择性达95.2%.催化剂重复使用三次后的性能基本保持不变. |

| Abstract: | A series of VOSO4/ACO(VO/ACO) catalysts were prepared by impregnation with oxygenated activated carbon(ACO) as support.The composition and structure of the prepared catalysts were characterized by FT-IR,XRD,BET and ICP.The catalytic effect of VO/ACO on the oxidation of ethyl lactate with molecular oxygen was investigated under atmospheric pressure.The results showed that modified activated carbon was an efficient support for catalysts containing VO2+.A VO-3/ACO can be obtained by impregnation in aqueous VOS... |
