1. Investigations intothe crystallization of butyl paraben
Abstract : In thisproject, solubility of butyl paraben in 7 puresolvents and 5 ethanol aqueous solvents has been determined at from 1 ℃to 50 ℃. Thermodynamic properties of butyl paraben have been measured by DifferentialScanning Calorimetey. READ MORE

2. Crystallization of Parabens : Thermodynamics, Nucleation and Processing
Abstract : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. READ MORE

3. Controlling Structure and Water Miscibility of Polyion - Surfactant Ion Complex Salts
Abstract : The interaction between poylions and oppositely charged surfactant ions has been investigated. This has been done by using the pure complex salt (polyion + surfactant ion) as a point of departure. Different parameters of the complex salt have been varied in a systematic way and the effect on structure and water miscibility has been investigated. READ MORE

4. Physical properties and crystallization of theophylline co-crystals
Abstract : This work focuses on the physical properties and crystallization of theophyline co-crystals. Co-crystals of theophylline with oxalic acid, glutaric acid and maleic acid have been investigated. The DSC curves of these co-crystals show that their first endothermic peaks are all lower than the melting temperature of theophylline. READ MORE

5. Spherical Crystallization of Benzoic Acid
Abstract : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. READ MORE
