摘      要：In this work,the etherification of glycerol with n-butanol catalyzed by sulfonic acid functionalized on KIT-6 mesoporous silica(SO_(3)H-KIT-6)was investigated for the production of valuable fuel *** SO_(3)H-KIT-6 catalyst was synthesized by co-condensation with different molar ratios of tetraethoxysilane and 3-mercaptopropyl(methyl)di-methoxy *** etherification reaction was systematically examined to determine the optimal reaction temperature,reaction time,catalyst loading,and glycerol to n-butanol ratio under autogenous *** maximum glycerol conversion and di-glyceryl n-butyl ether(di-GNBE)selectivity were 59.09 and 51.50%,respectively,when the SO_(3)H-KIT-6 catalyst with the highest acidity was ***,the presence of a methyl group on the catalyst surface prevented glycerol adsorption during the reaction process,leading to the inhibition of undesired product *** SO_(3)H-KIT-6 catalyst could be reused up to three times,with only a 13%decrease in glycerol conversion being ***,the superior performance of the SO_(3)H-KIT-6 catalyst for di-GNBE production was also demonstrated compared with conventional solid acid catalysts including HZSM-5,H-beta zeolite,Amberlyst-35,and Amberlyst-36.
