MCM-41负载钴催化H2O2氧化四氢萘合成α-四氢萘酮
摘要:
比较了醋酸溶液中过渡金属(Fe、Co、Ni、Ce、Cu、La、Zr或Cr)掺杂MCM-41催化过氧化氢氧化四氢萘合成α-四氢萘酮的转化率和选择性,发现其中Co/MCM-41的催化活性最好。探讨了Co/MCM-41作催化剂时反应温度、反应时间、催化剂用量等对四氢萘氧化的转化率和形成四氢萘酮选择性的影响,确定了较优的反应条件:m(四氢萘):m(催化剂)=12.5:1;反应温度T=383 K,反应时间8 h。四氢萘的转化率达94.7%,α-四氢萘酮的选择性达到70.3%。在反应体系中,Co/MCM-41是一种固体非均相催化剂。催化剂Co/MCM-41可回收重复使用3次,催化活性基本不变。

Catalytic Oxidation of Tetralin to α-Tetralone with Hydrogen Peroxide over Cobalt Loaded MCM-41
Abstract:
The conversions and selectivities of the oxidation of tetralin to α-tetralone in acetic acid with H2O2 as oxidant over transition metals(Fe,Co,Ni,Ce,Cu,La,Zr and Cr) loaded MCM-41 were compared.An excellent conversion of tetralin and high selectivity of α-tetralone were also obtained when Co/MCM-41 was used.The effects of reaction temperature,reaction time and catalyst concentration on the catalyst performance were examined in order to optimize the conversion of tetralin and selectivity of α-tetralone.A selectivity of 70.3% of tetralin to α-tetralone was obtained at 94.7% conversion of tetralin under the optimum reaction condition:m(tetralin):m(catalyst) =12.5:1;reaction temperature=383 K,reaction time=8 h.Co/MCM-41 act as a solid heterogeneous catalyst in the reaction system and it can be recycled three times without losing its activity to a great extent.
