A new solid acid SO42−/TiO2 catalyst modified with tin to synthesize 1,6-hexanediol diacrylate

This work aimed to modify the solid acid catalyst used to synthesize 1,6-hexanediol diacrylate. The SO42−/TiO2 catalyst doped with tin is superior to the unmodified catalyst, which is explained by the structural features, acidity and thermostability of the modified catalyst.
