Abstract
Poly(4-styrenesulfonic acid) brush-grafted silica particles, synthesized by surface-initiated atom transfer radical polymerization, were employed as a reusable acid catalyst for dehydration of fructose to 5-hydroxymethylfurfural (HMF) in water. The particles exhibited a high activity with the HMF yield of up to 31%, in contrast to 26% from the corresponding free homopolymer catalyst.
摘要
通过表面引发原子转移自由基聚合合成的聚苯乙烯磺酸刷接枝二氧化硅颗粒被用作可重复使用的酸催化剂，用于将果糖脱水为 5-羟甲基糠醛（HMF）在水中。与相应的自由均聚物催化剂的 26%相比，这些颗粒表现出很高的活性，HMF 的产率高达 31%。
