534 in the vapor increases with increasing concentration of acid (consistent wit Equation 17) and, at a given level of acid strength, with increasing pyridine-to-acid mole ratio, see Figures 2 and 3, Tables VI and VII. Although it was expected that quinoline should behave similar to pyridine, such was not the case. Quinoline was realized in the distillate i of the Othmer still; however, the quinoline concentration lis significantly lower than pyridine for a given mole ratio of base to acid. Two factors, ,~ low vapor pressure and low solubility, cause problems in the quinoline I system. Because of the relatively poor solubility of quinoline in water ; -(0.08 g/100 ml at.25 C), recovery of quinoline as a distillate product depends on the limitations of a steam distillation system. Accordingly, the distillate composition is a function of the vapor pressure of quinoline ': at the boilihg point of the mixed liquid phase. Because of the low volatility of quinoline, only about 2 weight percent quinoline is realized in the distillate during the regeneration step. Thus, typical Othmer equilibrium data are not realized for quinoline. Therefore, although quinoline can be recovered by a cyclic 1 regenerative process, the system is not analogous to the pyridine system. The quinoline system appears suitable on the basis of ApK data, but other factors such as solubility and volatility must be considered for practical application. Summary A method for selecting reagents for recovery of weak bases from hydrocarbon streams has been developed, based on thermodynamic ionization equilibrium constants. An,acid can be selected for recovery of a given base according to the value of ApK calculated for the system. Experimental data have been presented on the pyridine - sulfuric acid system, the pyridine - phosphoric acid system, and the quinoline - sulfuric acid system and demonstrate the utility and limitations of the method. The technique should also be applicable to development of systems \ When it is required to effectively remove nitrogen ' for recovery of acids from effluent streams by extraction with selected nitrogen base reagents. impurities in conjunction with a subsequent refining operation on a hydrocarbon stream, a regenerative process may also be applicable; however, provision must be made for adequate removal of nitrogen bases by using a sufficient number of extraction stages.
