Yang, Zhiwang published the artcilePreparation and application of SO42-/SnO2/SBA-15 solid acid catalyst for acetalization of cyclic ketones, Synthetic Route of 177-10-6, the publication is Cuihua Xuebao (2012), 33(5), 827-832, database is CAplus.
SO42-/SnO2/SBA-15 catalyst samples with different amounts of SnO2 were prepared by a wetness impregnation method and characterized by X-ray diffraction, N2 adsorption-desorption, and transmission electron microscopy. Their catalytic performance for the acetalization of 4-tert-butylcyclohexanone with glycol was investigated. The results showed that SBA-15 supported SO42-/SnO2 improved the catalytic activity markedly, which was caused by the increasing surface area of the sulfated tin oxide. The catalytic performance of SO42-/20%SnO2/SBA-15 for acetalization of several cyclic ketones with diols was also explored. Under the optimum conditions, a series of cyclic ketones such as cyclohexanone, 4-methylcyclohexanone, and 4-tert-butylcyclohexanone were well transformed into the corresponding products. The catalyst can be reused for several times without any significant loss in catalytic activity.
