A Mg–Al layered-double hydroxide (LDH) intercalated by sulphonato-salhen-chromium (III) complex was prepared and then used to the selective oxidation of benzyl alcohol by 30% H2O2. without any organic solvent, phase transfer catalyst or additive. The results revealed that the LDH hosted chromium complex exhibited much higher catalytic performance than its homogeneous analogue. Under the optimal reaction conditions, the highest conversion of benzyl alcohol reached 52.1%, with 100% of the selectivity to benzyldehyde.

HPW/C catalysts were prepared using impregnation method. The physical chemistry properties of the catalysts were characterized employing XRD and NH3-TPD.The effects of HPW loading, catalyst amount and reaction time on the catalyst performances were investigated. The results more acid content and active center contribute to the reaction performance. Under the optimal reaction conditions of 0.8g 29%(w) HPW/C as the catalyst, n(adipic acid): n(ethanol):n(toluene)=1:6:1,5h,the etherification rate was 97.3%.
