13.2: Saturated Solutions and Solubility - Chemistry

WebCrystallization is a separation and purification technique employed to produce a wide variety of materials. A solution is a mixture of two or more species that form a homogeneous single phase. Solutions are normally thought of in terms of liquids; however, solutions may include solids and even gases. WebInitial solubility determines the size of the crystallizer, while the temperature coefficient of solubility determines the yield. In the case of drowning out crystallization the solvent should have high solubility for the solute, while the solubility should decrease greatly when the anti-solvent is added.

WebCrystallization substantially reduced the oxygen permeability. Analysis of oxygen-transport parameters in terms of a two-phase structural model that considered a dispersion of lower-permeability spherulites in an amorphous matrix of higher permeability revealed that dedensification of the PET interlamellar amorphous regions was responsible for ... The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties. Nucleation is the step where the solute molecules or atoms dispersed in the solvent start to gather into clusters, on the microscopic scale (elevating solute concentration in a small region), that become stable under the current operating conditions. These stable clusters constitute the nuclei. Therefore, the clusters …

WebCrystallization is the production of a solid (crystal or precipitate) formed from a homogeneous, liquid which is concentrated to supersaturation levels (concentration > solubility) at that temperature. The available crystallization processes are the following three, Supersaturation by cooling the solution with trivial evaporation. WebCrystallization is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to cool, the solute is no …
