Additional information

Referring to the WoE approach, Beilstein database (2006), Budavari (1996) as well as Wallach (1850) state that 1 volume of water dissolves 959 volumes of monomethylamine in gaseous form at a temperature of 25 °C. Additionally, it was indicated that the substance is miscible in all proportions under pressure influence (Stephenson, 1993).
