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.
