| 发明名称 | Process for the preparation of hydroxy gallium phthalocyanine | ||
| 摘要 | The present teachings describe a process for converting a HOGaPc Type I polymorph to the HOGaPc Type V polymorph. The process includes obtaining a slurry comprising hydroxy gallium phthalocyanine (HOGaPc) Type I polymorph. The slurry is mixed at a resonant frequency of the slurry by applying a low frequency acoustic field for a time sufficient to convert the HOGaPc Type I polymorph to the HOGaPc Type V polymorph. | ||

| 主权项 | 1. A process comprising: obtaining a slurry comprising hydroxy gallium phthalocyanine (HOGaPc) Type I polymorph, a solvent and milling media; and mixing the slurry at a resonant frequency of the slurry by applying a low frequency acoustic field for a time of from about 5 minutes to about 40 minutes to convert the HOGaPc Type I polymorph to a HOGaPc Type V polymorph. | ||
