| abstract | Powder of the compound represented by the general formula (A). For example, the powder has a mode particle diameter D m measured by a laser diffraction scattering method of 75 to 150 μm, and the content of Ca ions is less than 1 ppm. In the general formula (A), R 1 to R 8 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a halogen atom or an amino group. This powder can be obtained, for example, by a method including the following steps: (i) a melting step in which a raw material containing the compound represented by the general formula (A) and an aqueous dispersion medium (a compound represented by the general formula (A) are mixed A poor solvent) is put into a container and heated to melt the raw material in the presence of an aqueous dispersion medium to obtain a heterogeneous liquid; (ii) a crystallization step, by cooling the heterogeneous liquid, the melt is crystallized. |
