For the purifications of the organic compounds, the fractional fusion method,that is, the zone melting method, was investigated from a point of view of chemical engineering.　Anthracene was used for the experiment as a sample. Phenanthrene was removed from Anthracene by the fractional fusion method.　The driving rate of heating device, the cooling method, and the pass number of the melting zone, etc., were investigated experimentally for the establishment of the suitable condition of the fractional fusion method of organic compound.　Usually, organic ompounds have small heat conductivities. The coring phenomenon, therefore, was recognized in the fractional fusion method, especially in the large scale of the treatment.　The following general equation was derived theoretically to explain the coring phenomenon.　Cxy/C_0 = 1 - (1 - k) exp { - (k/l) ((fy + vx) / v)}　The suitable procedure on a large scale of the fractional fusion method will be presumed from the general equation. presented
