Oiling-Out and Crystallization of Vanillin from Aqueous Solutions

Dynamic light scattering experiments performed on precrystalline liquid solutions that shows oiling‐out at higher vanillin concentration resulted in scattering from assumed precrystalline clusters. The structures appear during crash‐cooling into the supersaturated area and grow to µm size. They decrease in size and number at the appearance of visible crystals and might be unstable amorphous phases or or precrystalline structures that fit into...
