An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …
