2 dissolves into the solvent, it binds chemically to the amine at finite rates of reaction, forming reaction products. At low temperatures, these reaction products are stable and require heat and stripping vapor to decompose them and reverse the reactions. On the other hand, when H 2S dissolves into an amine, it converts.
