Stability |
DMF is stable. It is hygroscopic and easily absorbs water form a humid atmosphere and should therefore be kept under dry nitrogen. High purity DMF, required for acrylic fibers, is best stored in aluminum tanks. DMF dose not change under light or oxygen and does not polymerize spontaneously. Temperatures >350 °C may cause decomposition to form dimethylamine and carbon dioxide, with pressure developing in closed containers. |
