High acidity cellulose sulfuric acid from sulfur trioxide: a highly efficient catalyst for the one step synthesis of xanthene and dihydroquinazolinone derivatives
A cellulose sulfonate catalyst (HS-cellulose sulfonate) with high stability, excellent catalytic activity and high acidity value (about 1.55 mmol g(−1)) was successfully prepared by SO(3) gas phase sulfonation. The basic morphology and nanostructure of the catalyst were determined by HRTEM, XRD, IR,...
