experimental physchem properties

Melting Point: -180 C

The melting point of a crystalline solid is the temperature range at which it changes state from solid to liquid. See also: Melting Point

Boiling Point: 36 - 37 C

The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. See also: Boiling Point

Flash Point: -18 C (closed cup)

The flash point of a flammable liquid is the lowest temperature at which it can form an ignitable mixture in air. See also: Flash Point

miscellaneous

Appearance: colourless liquid

Visual appearance of the given substance.

Stability: Stable. Highly flammable - note low flash point. Incompatible with oxidizing agents.

Chemical stability occurs when a substance is in a (dynamic) chemical equilibrium with its environment. See also: Chemical Stability

Safety: Safety glasses. Good ventilation. Remove all sources ofignition from the working area.
