IONIC LIQUIDS

Ionic liquids are a class of organic salts with relatively low melt-

ing points. The term usually implies a melting point of 100°C or

lower, and many are liquid at room temperature. They offer several

advantages as solvents, such as very low vapor pressure, good ther-

mal stability, and nonflammable behavior. For these reasons they

are attractive as constituents of environmentally friendly chemical

processes.

This table lists some of the ionic liquids that have been studied.

The following properties are given:

Mol. Form. — molecular formula in the Hill convention

CASRN — Chemical Abstracts Service Registry Number

Mol. Wt. — molecular weight (relative molar mass)

t

m

— normal melting point in °C; the notation “gl” indicates a

glass–liquid transition, rather than a crystal–liquid transi-

tion

ρ — density in g/cm

3

. The subscript indicates the temperature

in °C; if there is no superscript, room temperature can be

assumed.

η — viscosity in mPa s. The subscript indicates the tempera-

ture in °C; if there is no superscript, room temperature can

be assumed.

The phase behavior of ionic liquids can be complicated. Some

are crystalline at low temperatures and show a sharp transition

from crystal to liquid state (a true melting point) as the tempera-

ture is raised, but others exist as a glass at low temperatures and

convert to a liquid at the glass–liquid transition temperature, de-

noted by a small change in heat capacity. Still others are glasses at

very low temperatures, transform to crystals as the temperature is

raised, and finally become liquid at a still higher temperature. See

Reference 3 for a discussion of the types of phase behavior.
