Melt Crystallization Technology

Accurately control the temperature and integrate a number of technologies for efficient purification.

Technical Principle Of Melt Crystallization

Characteristics of Melt Crystallization Technology

1

High product purity: The product purity can be above 99.99% chromatographically pure according to customer requirements.

2

Low operating temperature: Generally, it is operated at atmospheric pressure and low temperature, with simple and safe operation.

3

Wide applicability: It is very difficult to separate isomers and chiral substances by distillation, while separation can be easily achieved by melt crystallization.

4

No solvents required: The crystallization process does not require the addition of other solvents, which can effectively avoid the increase of impurities caused by the introduction of solvents and environmental pollution.

5

Investment saving: There are no excessive requirements for equipment, which can reduce costs and equipment investment.

6

Energy conservation and environmentally friendly: The energy consumption of melt crystallization is generally only 10%-30% of that of distillation.
