杂多酸催化环己烯氧化合成己二酸
摘要:
以30% H2O2作氧化剂,二元羧酸或8-羟基喹啉等作助剂,考察了杂多酸催化环己烯氧化合成己二酸的活性,讨论了催化剂和助剂对反应的影响。结果表明,钨磷酸在环己烯氧化合成己二酸的过程中显示了较高的催化活性。8-羟基喹啉作助剂时,己二酸的收率最高,反应6 h,己二酸的收率可达75.0%;草酸作助剂时,反应的最佳条件为,n(环己烯):n(H3PW12O40):n(H2C2O4):n(H2O2)=100:1:1:538,反应温度为92℃,反应时间为6h,己二酸的收率可达70.1%。十六烷基三甲基溴化铵、溴代十六烷基吡啶作相转移催化剂时,己二酸的收率也较高,反应6 h,己二酸的收率分别为73.1%和71.6%。对钨磷酸催化环氧环己烷、反-1,2-环己二醇氧化合成己二酸的活性也进行了研究。

Catalytic Oxidation of Cyclohexene to Adipic Acid over Heteropolyacids
Abstract:
The oxidation of cyclohexene to adipic acid catalyzed by heteropolyacids has been investigated,using 30% aqueous hydrogen peroxide as an oxidant,and dicarboxy licacids or 8-hydroxyquinoline as cocatalyst.Adipic acid in yield up to 75.0% was obtained in 6 h,in the presence of 8-hydroxy quinoline.When oxalic acid was used as cocatalyst in condition of 92℃,6 h,n(cyclohexene):n(H3PW12O40):n(H2C2O4):n(H2O2)=100:1:1:538,the yield of adipic acid was 70.1%.When cetyltrimethyl ammonium bromide or cetylpyridinium bromide was used as phase transfer catalyst,the yield of adipic acid was 73.1% and 71.6% respectively.Catalytic oxidation of cyclohexene oxide or trans-1,2-cyclohexanediol to adipic acid over tungtophosphoric acid were also carried out in order to confirm the reported mechanism of the reaction.
