Are methyldiethanolamine and dimethylethanolamine the same thing?
Not one of a kind! Methyldiethanolamine is obtained by the reaction of formaldehyde and diethanolamine, and dimethylethanolamine ethylene oxide method is obtained by ammoniating dimethylamine and ethylene oxide, followed by distillation, rectification, and dehydration.
The former is an N with two ethanol groups -CH2CH2OH and a methyl-CH3
The latter is an ethanol group-CH2CH2OH and two methyl-CH3 connected to an N
N-methyldiethanolamine is a chemical substance with the molecular formula C5H13NO2. Containing two hydroxyl groups and one amino group, the hydroxyl group lowers the vapor pressure, increases the solubility, is beneficial to the absorption of acid gas, can increase the concentration, reduce the circulation volume, and reduce energy consumption.
(N,N-Dimethylethanolamine) referred to as DMEA, is a colorless and volatile liquid with an ammonia smell and a boiling point of 134.6°C. Used for ion exchange resin; used for high-purity water preparation and sugar solution decolorization, film lotion three waste treatment, etc.; used for polyurethane flexible block foam, molded foam and rigid foam, smoldering elastic foam, etc.; used as water-soluble coating Co-solvent, polyurethane paint curing agent; reaction product with acrylic microorganisms as flocculant in urban water purification field. This product has severe irritating effects on eyes, skin, mucous membranes and upper respiratory tract. May cause skin burns. Inhalation can cause laryngeal and bronchial inflammation, edema, spasm, chemical pneumonia, pulmonary edema, etc. May cause sensitization to the skin.
