Single-Pass Reaction Column System with Super Brønsted Acid-loaded Resin

Abstract

Various acid-promoted reactions gave the desired products in high yields by passing a solution of reactants through a reaction column packed with polystyrene-bound super Brønsted acid (1) just once. Polar and nonpolar organic solvent-swellable 1 is much superior to Nafion^® SAC-13 (2) as a Brønsted acid-loaded resin packed in the column.

Brønsted acid - reaction column - flow system - resin - catalyst
