CRYSTALLIZATION SYSTEM UTILIZING ATOMIZATION

摘要

Crystallization of an organic pharmaceutical compound is achieved by atomization of one solution and introduction of the atomized solution into a vessel containing a second solution where the solutions are mixed to form a product. The process can be performed on non-reactive constituents such as a solution containing the compound to be crystallized dissolved in a solvent and an anti-solvent solution. Alternatively, the process can be performed on reactive constituents, such as solutions of solvents containing different reactive intermediates, under proper reactive conditions. The process may be practiced continuously or in batch mode. Atomizers of the non-pressure-driven ultrasonic type or of the ultrasonic or non-ultrasonic pressure-driven type can be utilized.
