Alfa Chemistry Materials Diethylenetriamine
Material Notes: Applications: Diethylenetriamine is manufactured by reacting ethylene dichloride and ammonia. It is used as a solvent, in organic syntheses, and in a variety of industrial applications including use as a fuel component.

DIETHYLENETRIAMINE is a yellow liquid with an ammonia-like odor. Less dense than water. Corrosive to metals and tissue. Vapors heavier than air. Burns, although possibly difficult to ignite. Toxic oxides of nitrogen produced during combustion. Used as a solvent for plastics and dyes and in chemical synthesis.

CORROSIVE TO COPPER & ITS ALLOYS; 1 MG/L EQIV TO 237 PPM; 1 PPM EQUIV TO 4.22 MG/U M; HYGROSCOPIC; Heat of vaporization: 487.7 J/g @ 40 kPa
