%X The formation of Schiff bases between methylamine and m- and p-hydroxybenzaldehydes has been studied by spectrophotometry. Because of overlapping equilibria and ionic strength effects, the formation constants, KF, of the neutral Schiff bases are determined with less precision than for the ortho compound. In dilute solution they are estimated by extrapolation to be 1.0 x 103 and 1.0 x 104, respectively. The formation constants, KA, of the anionic forms of the Schiff bases have been more precisely measured as 1.45 x 102 and 5.52, respectively. The equilibria are compared with those for salicylaldehyde.
