Amine functionalized silica catalysts (3-aminopropyltrimethoxysilane (APTMS)) NH2/SiO2, (Diazabicycloundecene/SiO2) DBU/SiO2 and (1,5,7-triazabicyclo[4,4,0]dec-5-ene/SiO2) TBD/SiO2, which were characterized by Si-29 NMR, element analysis and indicator dye adsorption, were prepared by ultrasonic technique under mild conditions. Such hybrid solid bases showed high catalytic activity and good reusability towards for the synthesis of propylene glycol methyl ether.
