Mesoporous sBa-15 silica catalyst functionalized with phenylsulfonic acid groups (SbA-15-ph-So(3)h) as efficient nanocatalyst for chemoselective thioacetalization of carbonyl compounds

摘要

In this research a Nano acidic catalyst was prepared and its efficiency on thioacetalization of carbonyl compounds was examined. For this aim we used modified SBA-15 as support, which have been modified by phenolic and sulfonic acid. SBA-15 is a member of mesoporouses. Mesostructures-based properties such as large specific surface, low specific weight, chemical and thermal resistance have been used in different fields such as catalyst, drug delivery, chromatography, microelectronic, separation and purification. Based on our knowledge mesoporoses are ideal catalysts and usually have been used as solid catalyst, which have been modified by organic groups and metal oxides. These types of application are based on the large dispersability of the modifier groups at mesoporouses.
