Crystallization via highshear transformation Wei, Chenkou
Jul 20, 2006· The process may also include the step of introducing seed crystals into the vessel to facilitate crystallization. The seed crystals may be placed into the vessel prior to the introduction of the solutions or seed crystals may be added to one of the solutions prior to its introduction into the vessel.
Crystallizers Swenson Technology
Crystallization is the process by which a chemical is separated from solution as a highpurity, definitively shaped solid. A crystal may be defined as a solid composed of atoms arranged in an orderly, repetitive array.

Msmpr Crystallization Term Paper
...Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely depositeddirectly from a gas. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.

Setup of Reflux apparatus UCLA
In order to speed up reactions or to increase the solubility of a compound, chemists often times reflux reaction mixtures. This step implies that the reaction mixture is brought to a boil. The lowest boiling compound in the mixture determines the temperature when this occurs, usually the solvent. It condenses and returns into the reaction vessel.
The role of oil in macromolecular crystallization: Structure
Figure 4 Determination of the contact area between a crystallization trial and its supporting vessel by the application of oil. (a) Large contact area: a crystallization drop dispensed onto the floor of a vial and then covered by a layer of oil; the drop spreads out and flattens over the floor of the container.
Crystallization
crystallization, is usually accomplished by the removal of solvent or by lowering the solution temperature. The driving force for the formation and growth of crystals is related to theforce for the formation and growth of crystals is related to the extent of supersaturation. 9
