💡 Commercial Applications
Monoethanolamine, commonly known as MEA, is a versatile chemical compound that finds wide applications in various commercial and industrial sectors. In the commercial realm, it is primarily used as a key ingredient in the production of personal care products such as shampoos, conditioners, and lotions. Its ability to act as a pH adjuster and emulsifying agent makes it a popular choice for formulating these consumer goods.
Moreover, Monoethanolamine is extensively utilized in industrial processes such as gas treatment and corrosion inhibition. In the gas treatment sector, MEA is employed as a solvent for removing acidic gases like hydrogen sulfide and carbon dioxide from natural gas streams. Its unique chemical properties make it an effective agent for capturing and neutralizing these harmful compounds, thus ensuring the purity of the final gas product.
In contrast to its commercial and industrial applications, Monoethanolamine also plays a significant role in the pharmaceutical industry. Its use as a precursor in the synthesis of various drugs and medications makes it a crucial component in pharmaceutical manufacturing. MEA’s ability to react with other chemicals to form new compounds allows for the creation of complex pharmaceuticals that address a wide range of medical conditions.
⚗️ Chemical & Physical Properties
Monoethanolamine is a colorless to pale yellow liquid with an ammonia-like odor. It is commonly used in applications such as gas scrubbing, detergents, and personal care products.
The molar mass of Monoethanolamine is approximately 61.08 g/mol, with a density of about 1.02 g/cm3. This puts it in the range of common household items such as acetic acid and ethylene glycol in terms of molar mass and density.
Monoethanolamine has a melting point of around 10.9°C and a boiling point of about 170.6°C. These values are similar to those of water, putting it in the same range as common household items in terms of melting and boiling points.
Monoethanolamine is highly soluble in water, forming clear, colorless solutions. It has a relatively high viscosity, making it useful in applications where thickening or binding properties are desired. This makes it similar to substances like glycerin in terms of solubility in water and viscosity.
🏭 Production & Procurement
Monoethanolamine, a versatile organic chemical compound, can be produced through the reaction of ammonia with ethylene oxide. This process results in the formation of a primary amine, which is then reacted with ethylene oxide to yield Monoethanolamine.
Monoethanolamine can be procured from various chemical manufacturers or distributors who produce it in large industrial plants. It is commonly transported in bulk via tank trucks or railcars to facilities where it is used in various industrial processes. Additionally, Monoethanolamine can also be purchased in smaller quantities for laboratory or research purposes.
The procurement of Monoethanolamine typically involves establishing contracts with suppliers to ensure a steady and reliable source of the chemical. Companies may choose to work directly with manufacturers or utilize intermediaries such as chemical distributors to obtain Monoethanolamine. Proper handling and transportation protocols must be followed to ensure the safe and efficient delivery of the chemical to its intended destination.
