Methyl Diethanolamine is a clear, colorless or pale yellow liquid with an ammonia odour. It is miscible with water, alcohol and benzene. Methyl diethanolamine is also known as a MDEA or N-Methyl diethanolamine and has the formula CH3N (C2H4OH)2. Methyl diethanolamine is widely used as a sweating agent or decarbonizer in chemical, oil refinery, syngas production and natural gas. This compound should not be confused with similarly named MEA or DEA and the commercial drug MDEA
