摘要： 考察了由不同金属酞菁(MPc,M=Fe,Co,Cu)、氯代金属卟啉(MTPPCl,M=Fe,Cr,Mn)和Pd(OAc)2(醋酸钯)/HQ(氢醌)组成的催化体系对环己烯氧化成环己酮的催化活性,结果表明,在乙腈酸性水溶液中,Pd(OAc)2/HQ/FePc催化体系对环己烯氧化合成环己酮显示出较高的催化活性,在30min内环己酮收率可达84%,选择性>98%.研究了各种因素对体系催化活性的影响.

Abstract: Cyclohexene has been oxidized to cyclohexanone catalytically by catalyst systemsof Pd(OAc)2/HQ with macrocyclic compounds:metallophthalocyanine(MPc,M=Fe,Cr,Co)and chlorometalloporphyrin(MTPPCI,M=Fe,Cr,Mn)in an acidic aqueous solution ofacetonitrile.The best results were obtained by using Pd(OAc)2/HQ/FePc system.The vieldof cyclohexanone was 84%with selectivity of 98%on 30min reaction.Some factors influenc-ing the activity of the catalyst have been examined.

Key words: cyclohexene, cyclohexanone, catalytic oxidation, palladium acetate, phthalocya-nine iron, hydroquinone
