It is used in a variety of industrial applications including the production of resins, pharmaceuticals and cosmetics. It is also used as a corrosion inhibitor and defoamer.

DMEA can be synthesized by reacting acetaldehyde with ammonia and formaldehyde. The reaction is carried out in the presence of a catalyst such as hydrochloric acid. The reaction is exothermic and the product is a mixture of DMEA and 2-methylaminoethanol (MEA). MEA can be separated from DMEA by distillation.

The following is the chemical formula for the synthesis of DMEA:

CH3CHO + NH3 + CH2O -> (CH3)2NCH2CH2OH
DMEA can also be synthesized by the reaction of ethylamine and formaldehyde. The reaction is carried out in the presence of a catalyst such as hydrochloric acid. The reaction is exothermic and the product is a mixture of DMEA and ethanolamine (EA). EA can be separated from DMEA by distillation.

This is the chemical equation for the synthesis of DMEA from ethylamine:

CH3CH2NH2 + CH2O -> (CH3)2NCH2CH2OH
DMEA is a hazardous substance. It is flammable and irritating to skin and eyes. It is also a potential carcinogen.

DMEA should be stored in a cool, dry place. Keep away from heat, sparks and open flames. Dispose of in accordance with local regulations.
