Measuring the amount of crystallinity in solutions using DSC

摘要

The amount of solid that forms in a solution at temperatures below the cloud point, is an important quantity in the design of crystallization processes. A new method using differential scanning calorimetry (DSC) to measure the fraction of crystallized solution, α_solution~S, is proposed. A very good agreement is obtained between the data measured by the new calorimetric method and using alternative techniques. A simple graphic version of the calculation procedure is also pre- sented.
