ABSTRACT
A new heterogeneous organocatalyst, graft polymer supported dimethylaminopyridine (g-DMAP), is developed. This catalyst has a flexible structure and comprises DMAP anchored to the polyethylene-graft-polyacrylic acid (PE-g-PAA). It exhibits higher activity than DMAP supported on polystyrene cross-linked with divinylbenzene and can be recovered in batch mode acetylation. The activity and stability of this catalyst allow its application in continuous flow systems. Continuous acetylation proceeds with excellent conversion, and a turnover number of 560 can be achieved using g-DMAP. Parallel fixed bed reactors were used to scale up the synthesis of this continuous flow system. Eight parallel fixed bed reactors displayed excellent conversion.
