| Abstract: | By hydrothermal method,using hexadecyltrimethylammonium bromide as template agent,sodium silicate as silica source,adding separately the transition metal heteroatoms Cr~(3+),Co~(2+) and Fe~(3+) in the synthesis process and crystallizing at 150 ℃ for 48 h,the mesoporous molecular sieves containing heteroatoms Cr-MCM-41,Co-MCM-41 and Fe-MCM-41 were synthesized.The oxidation reaction of cyclohexane was studied and the optimum reaction conditions were obtained,that is,temperature 100 ℃,cyclohexane 30 mmol,0.12 g Cr-MCM-41 used as catalyst,n(H_2O_2)/n(C_6H_(12))=1.0 and reaction time 16 h.Conversion of cyclohexane reached 28.6%.Mole ratio of cyclohexanone to cyclohexanol in the product was 1.89. |
