Solubility of potassium methylamide in aminomethane

The solubility of potassium methylamide in aminomethane is measured over the temperature range -78" to 40°C. The solubility is 39 f 3 g K/kg amine at -78°C and decreases with increasing temperature. The solubility of potassium ethylamide in aminomethane increases markedly with temperature and is approximately 90 g K/kg amine at -40°C. Potassium also dissolves in and reacts with 1 -aminopropane, 1,2diaminopropane, and 1,2-diaminoethane.
