Crystallization Study of Ionic Liquid

Ionic liquid are salts that are liquid at low temperature, usually have melting point below
100°C. They are getting wide attention recently because of their variety potential in the
industry. Like other salts, ionic liquid also can be crystallizing. This project will present the
study on crystallization of ionic liquid as it is important as one of possible methods to
recycle and regenerate ionic liquids. A vrami analysis was utilized to study the crystallization
kinetics of ionic liquid. Avrami exponent n is slightly increased and the parameter k
decreased with increasing ionic liquid percentage on the solution. The increase in
temperature led to an increase in the value of A vrami exponent while the value of parameter
k dropped significantly. The value of Avrami exponent obtained is in the range of (0.3-2.1).
The nucleation process is instantaneous and the crystal growth is in 2D dimension.
