摘要：
The dissociation constants of 1,2,3,4-tetrahydro-8-oxyquinoline in aqueous solution, pK(1) = 5.51 +/- 0.07 and pK(2) = 9.7 (298 K), were determined by pH-metric titration and computer simulation. The influence of heteroring hydrogenation on the acid-base properties of 8-oxyquinoline is discussed.
