What is the pKa of 2, 6-lutidine?
The pKa of 2,6-lutidine is 6.6 (3), which indicates that 2,6-lutidine will partially exist in the protonated form in water and moist soils and cations will not volatilize (SRC). 2,6-Lutidine may volatilize from dry soil surfaces (SRC) based on its vapor pressure of 5.65 mm Hg at 25 deg C (4).
