Liquid-liquid interfacial crystallization has been developed as a new crystallization method. This method makes it possible to produce the asymmetric crystals, porous particles and composite particles.
In this paper, the principle of liquid-liquid interfacial crystallization was introduced using measuring the electric conductance and molecular dynamics simulation at interface. The crystal growth or particle morphology was controlled by difference of the mutual solubility between water and organic solvent. The asymmetric NaCl crystals were created at the liquid-liquid interface using the mutual solubility. The glycine/silica particles were produced since glycine crystals were precipitated on the silica surface by atomizing process based on the liquid-liquid interfacial crystallization. Moreover, the porous alanine particles were produced with an inkjet nozzle. Adjusting the droplet size in the crystallization with an inkjet nozzle was found to be feasible for controlling particle size of alanine.
