Schiff base equilibria. III. N-Methylsalicylideneimine

Abstract

At 25º the formation constant of the Schiff base of salicylaldehyde and methyl- amine is 3.72 x 10⁴; and the pK of the phenolic group of the Schiff base is 11.7. The neutral form of the imine has distribution coefficients of 23.5 between water and toluene and 9.0 between water and cyclohexane.
