Abstract

The apparent dissociation constants An approximately linear relationship was found between the number of observations were made relative to the isolation and purification of these substances. Grignard reagents react with phosphorus trichloride only to the stage of disubstitution. of the acids were determined potentiometrically. methyl groups attached to a specific carbon in the alkyl group and the magnitude of pK'.
