    摘要: PROBLEM TO BE SOLVED: To provide a method capable of monitoring a crystallization process, in particular, a crystalline nucleus forming process and a crystal growing process over passage of time, and to provide a method for producing a crystal having a grain size suitable for manufacture or the like, based on the knowledge obtained by the method.
    SOLUTION: The method for monitoring crystallization process of a compound is performed by the use of solid
    13 C-NMR. Actually, the method is performed, by tracking how the signal intensity of each site derived from carbon atoms constituting the molecular structure of the compound changes, before the compound is held at a fixed temperature and crystallized, after it has been laid in a molten state by heating to a melting point or higher by the use of the solid
    13 C-NMR.
