AI Technical Summary
In existing technologies, tetraacetylribose has low catalytic efficiency, is difficult to recover, has poor compatibility with the acetic anhydride system, and is difficult to balance product yield and purity, resulting in long production cycles and high costs.
The efficient synthesis of tetraacetylribose was achieved by using the magnetically responsive bifunctionalized dicationic ionic liquid [Di-IM-C12][FeCl4]2 in synergistic catalysis with DMAP, through segmented temperature-controlled primary acylation, magnetically responsive separation and chemical replenishment of the catalyst, combined with controlled two-phase hydrolysis and controllable gradient crystallization.
It significantly improved the synthesis efficiency and product quality of tetraacetylribose, shortened the reaction time, increased the yield and purity, and achieved a total catalyst recovery rate of 97%, effectively saving overall costs.
