Definition and Application of MEA Monoethanolamine

Mea monoetanolamina is mainly used for buffering in pharmaceutical preparations and for the preparation of emulsions. Others include: as a solvent for fats and oils; as a stabilizer for phenytoin glucose solution for injection. MEA monoetanolamina can also be used to prepare various therapeutic salts. For example, vitamin C MEA monoetanolamina salt can be used for intramuscular injection, while salicylic acid MEA monoetanolamina salt and undecylenic acid MEA monoetanolamina salt can be used to treat rheumatism and as an antifungal agent, respectively. However, the most common therapeutic use of this product is as an injection of oleic acid MEA monoetanolamina and as a tissue sclerotic agent.

Mea monoetanolamina is very easy to absorb moisture and is unstable when exposed to light. The aqueous solution can be autoclaved. When storing large amounts of MEA monoetanolamina, it is best to use stainless steel containers for long-term storage. Copper, copper alloy, zinc, and galvanized iron containers can all be gradually corroded by amines. Therefore, these materials should not be used to make storage containers. Mea monoetanolamina can easily absorb moisture and CO2 in the air; it can also react with CO2. Separating the inert gas from MEA monoetanolamina prevents these reactions from occurring. Smaller amounts of MEA monoetanolamina should be placed in an airtight container protected from light and stored in a cool, dry place.

Mea monoetanolamina has a hydroxyl group and an amino group, so it can react uniquely to alcohols and amines. This product can react with acids to form salts and esters. When there are heavy metal salts, it can change color and precipitate out. This product reacts with acids, acid anhydrides, acyl groups and esters to form amide derivatives, and with propylene carbonate or other carbonic acid cyclic hydrocarbons to form corresponding carbonates or esters. Mea monoetanolamina has a primary amine that can react with aldehydes or ketones to produce aldimines and ketimines. In addition, MEA monoetanolamina can form double salts with aluminum, copper and copper alloys. It reacts violently with acrolein, vinyl nitrile, epichlorohydrin, propiolactone and vinyl acetate.

When handling concentrated MEA monoetanolamina solutions, personal protective equipment should be worn. For example, proper masks, chemical resistant gloves, safety glasses, and other protective clothing. The transfer or preparation of MEA monoetanolamina can only be carried out in a chemical fume hood. Mea monoetanolamina vapor can drift along the surface to a distant source of combustion and drift back to the original place.
