text: In this Example, a series of cycles is carried out in which the conditions of Example 81 are duplicated except that pyridine is added to the toluene desorbent (prior to admission to the adsorption column) in amounts corresponding to about 0.17 w % to 0.28 w % based on toluene.
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.
