熔点低，呈液态的温度范围广，化学和热稳定性较好，通常在高达300 C时

Low melting point, wide liquid temperature range, good chemical and thermal stability, usually not decomposed up to 300 C, and the lower the structural symmetry of the ionic liquid, the weaker the intermolecular force, positive or negative charge distribution The more uniform, the lower the melting point of the ionic liquid, and the larger the anion size, the lower the melting point of the ionic liquid.

Low melting point, liquid temperature range is wide, chemical and thermal stability is better, usually up to 300 C does not decompose, and the structure of the ionic liquid is less symmetrical, the weaker the force between molecules, the more uniform the yang or yin charge distribution, the lower the melting point of the ionic liquid, in addition to the larger the size of the ion, the lower the melting point of the ionic liquid.

The melting point is low, the temperature range of liquid is wide, the chemical and thermal stability is good, usually it does not decompose when it is up to 300 C, and the lower the structural symmetry of ionic liquid is, the weaker the intermolecular force is, the more uniform the charge distribution of cation or anion is, the lower the melting point of ionic liquid is, and the larger the ion size of vulva is, the lower the melting point of ionic liquid is.
