Abstract

Alkali metal picrates in an aqueous solution are extractable by nitrobenzene. The investigations of the equilibria in and between the aqueous and organic phases show that the larger the association constants in the aqueous phase and the dissociation constants in the organic phase, the greater the extractability of the salts. The extremely low extractability of alkali metal picrates can be well explained in terms of such equilibrium constants.
