03 · Physical and chemical properties
Dimethylethylamine properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.
| Property | Value | Conditions | Source |
|---|---|---|---|
| Boiling point | 36.5 °C (97.7 °F) | HSDB | |
| Melting point | -140 °C (-220 °F) | HSDB | |
| Density | 0.675 g/cm³ | at 20 °C | HSDB |
| Vapor pressure | 352 mmHg | Haz-Map | |
| Flash point | -12.22 °C (10 °F) | Haz-Map |

Further notes on Dimethylethylamine
These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.
Odor
Odor threshold measurements on 16 aliphatic amines were made with panels of specific anosmic & normal observers. The anosmia was most pronounced with low-mol-wt tertiary amines, but was also observed with lesser degree with primary & secondary amines.

Reactivity
DIMETHYLETHYLAMINE, [LIQUID] 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.
