Process Engineering Laboratory II Crystallization - ETH Z

Description of the crystallization setup The crystallization is conducted in a thermostated, 250 ml jacketed glass reactor (see gure 4(a)) equipped with a stirrer. A thermostat pumps a mixture of glycol and water through the jacket and uses a Pt100 thermocouple positioned in the reactor to control the reactor temperature.

In this review, we highlight particle based crystallization pathways leading to single crystals via mesoscopic transformation. In contrast to the classical mechanism of atom/molecule mediated growth of a single crystal, the particle mediated growth and assembly mechanisms are summarized as non-classical crystallization, including exiting processes like oriented …

The crystallizing reactor tank is a crystallizing device of which the chilled glycol water quickly cools down the jacket, thus the reactor. The type of the jacket, the structure of the agitator, and the form of the outlet all play an important role. Crystallization Reactor is used to achieve very high purity CBD on a large scale without complex ...
