"High Pressure Crystallization" is a newly developed crystallization process where pressure instead of cooling temperature is controlled as the motive force to crystallize or to melt. This process has already been applied in industry to separate an isomer from its mixture. Through experiments using this process to apply various organic mixtures, it was found that there are many phenomena different from the concept of the liquid-solid transition under atmospheric pressure, such as eutectic concentration shifts, a change from a solid solution system to a eutectic one, a change in the nucleation pressure caused by the history of the liquid, and others. Most of these phenomena might be caused by a change of the liquid structures under pressure. Some of them are discussed in this article.
