以具有三维孔道的SBA-1分子筛为载体,在其表面原位反应制备S·SnO_2/SBA-1催化剂。将合成的催化剂样品用于醛的氧化酯化反应,结果表明,在以过氧化氢为氧化剂的较温和反应条件下,S·SnO_2/SBA-1不仅可有效催化芳香醛氧化酯化反应,还可高效催化饱和醛和醇类反应,尤其对于一些长链的饱和醇有良好的催化活性。 The S · SnO 2 / SBA-1 catalyst was prepared by in-situ reaction on the surface of SBA-1 molecular sieve with three-dimensional pores. The synthesis of the catalyst sample for the aldehyde oxidation esterification reaction results show that the hydrogen peroxide as the oxidizing agent under the mild reaction conditions, S · SnO_2 / SBA-1 can not only effectively catalyze the aromatic aldehyde oxidation esterification, but also It can efficiently catalyze the reaction of saturated aldehydes and alcohols, especially for some long-chain saturated alcohols.
