attributed to eoin liquid methylamine. In liquid methylamine eswas found to decay by a first-order process with a rate constant equal to (6.1 + 0.6) X 105 sec-' at 293 K. In basic methylamine, a solution of sodium methylamide (CH3NHNa) in liquid methylamine, eslived longer than in neutral liquid methylamine and the decay was second order. The rate constant of this process is (6.6 + 0.13) X 105 e10oo liter -mole-' sec-1.
