H6P2Mo9W9O62/Cu3(BTC)2的制备及催化合成缩醛(酮)
Preparation of H6P2Mo9W9O62 /Cu3(BTC)2 and its catalytic performance for synthesis of acetals and ketals
摘要
Abstract
H6 P2 Mo9 W9 O62/Cu3 (BTC)2 as a new catalyst was prepared by impregnation method. Fourier transformation infrared spectrum (FT - IR ),X - ray diffraction (XRD ),thermal gravimetry (TG ) and scanning electron microscope (SEM)were used for characterization and measurement of its composition, structure,thermal stability and morphology. The reaction,with H6 P2 Mo9 W9 O62/Cu3 (BTC )2 as catalyst,for synthesis of ketal from cyclohexanone and ethylene glycol as starting materials was used as probe reaction,and the optimized synthesis conditions were found by orthogonal experiments as follows:fixing the amount of cyclohexanone as 0. 2 mol;molar ratio,n (cyclohexanone ): n (ethylene glycol )=1:1. 3;mass ratio of the catalyst to total reactants,0. 3%;the reaction time,60 min;and amount of water stripping agent,6 mL. The yield of the product reaches 83. 7%. Under similar reaction conditions,the yield of benzaldehyde ethylene glycol acetal reaches 70. 1%;butanone glycol ketal,66. 0%;butanone 1,2 -propylene glycol ketal,62. 1%;benzaldehyde 1,2 -propanediol acetal,66. 3%;and cyclohexanone 1,2 -propylene glycol ketal,75. 8%. Compared with that of catalysts H4 SiW12 O40/MCM-48,activated carbon supported p-toluene sulfonic acid and Al-cross linked montmorillonite,H6 P2 Mo9 W9 O62/Cu3 (BTC)2 shows better catalytic performance.关键词
