How To Develop More Robust Crystallization Processes

Crystallization and precipitation are critical processing steps in chemical development. They can serve as purification and separation steps, and have implications on the yield, purity and particle size distribution. Even though crystallization has advanced significantly over the past decade, many chemists have such short deadlines that they must base everyday decisions on past experience rather than understanding the crystals in situ. Due to the complexity of crystallization, a process may be developed simply by crashing solids out of solution and transferring a non-robust process with inconsistencies in the yield, purity and particle size distribution.

Impact of Process Parameters on Supersaturation and Crystal Size and Shape

This is the fifth blog post in a series dedicated to crystallization.  In case you missed the previous posts in the series, they are available here:

The diagram below illustrates the relationship between supersaturation and crystal size distribution, via crystal nucleation and growth. In this post, we will look at how supersaturation can be controlled by adjusting process parameters such as antisolvent addition rate. Continue reading
