text: Pyridine is preferably added with the desorbent toluene to balance pyridine removed from the adsorbent bed in the column effluent; the amount added depends on the pyridine loading of the adsorbent and the temperature of the adsorption column--typically it may be 0.01%-1.0%, say 0.2% of the desorbent toluene.
