N,N-Dimethylethylamine Chemical Properties,Usage,Production

Chemical Properties

colorless to light yellow liquid.

Uses

N,N-Dimethylethylamine is used as adhesive, sealant chemical and process regulator. It acts as an intermediate for quaternary ammonium compounds and is also used as a stabilizer for chlorinated hydrocarbons and vinyl derivatives. It is used in foundries as a catalyst for sand core production. Further, it is employed in the polymerization of polyamides. In addition to this, it is used in the preparation of polypeptide nanogels with self-reinforced endocytoses.

Uses

N,N-Dimethylethylamine was used in the preparation of pH and reduction dual-responsive polypeptide nanogels with self-reinforced endocytoses.

General Description

N,N-dimethylethylamine appears as a clear colorless liquid with a strong odor that can vary from ammonia-like to fishlike. Flash point of 10°F. Vapors irritate the eyes and mucous membranes. Less dense than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used in the manufacture of other chemicals.

Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

N,N-Dimethylethylamine is a base. Neutralize acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols, epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
