Synthesis of a Novel Solid Acid with both Sulfonic and Carbonyl Acid Groups and Its Catalytic Activities in Acetalization
The novel solid acid with both sulfonic and carbonyl acid groups has been synthesized from 3-((2-sulfoethoxy) carbonyl)acrylic acid and tetraethyl orthosilicate (TEOS). The catalytic activities were investigated through the acetalization. The results showed that the novel solid acid was very efficient for the reactions with the high yields. The high acidity
high stability and reusability were the key feature of the novel solid acid. Moreover
the sulfonic and carbonyl acid groups could cooperate during the catalytic process
which improved its catalytic activities. The catalyst shows recyclability
and hold great potential for replacement of homogeneous catalysts.
