A solution for dynamic determination of self-benzene crystallization point

The determination of the crystallization point of benzene is a characteristic index of the purity test of general industrial products.
In the low temperature cooling process, the pure liquid may appear too cold state, namely when at or below the temperature of crystallization point, the material is still in a liquid state without precipitation crystallization to coagulation state, the main reason is due to the static in the liquid, no enough seed formation, although reach even below the crystallization temperature at this moment, but not in crystallization.
When there is proper mixing in the system, with the cooling process, there are enough seeds to promote the formation of crystallization.
Therefore, when determining the crystallization point of benzene, it is clearly stated during the operation that the cooling operation is carried out and the liquid of the benzene sample is properly stirred.
If there is no agitation, the measured value will be too low, and there may be abnormal temperature increases during the measurement process.
