Patent number: 11753424Abstract: A crystalline form of phenyl bis (2,4,6-trimethylbenzoyl) phosphine oxide, with a large particle size, which belongs to a triclinic crystal system and space group P-1. A crystallization method for making the crystalline form of phenyl bis (2,4,6-trimethylbenzoyl) phosphine oxide, comprising adding a solid of phenyl bis (2,4,6-trimethylbenzoyl) phosphine oxide to a solvent and mixing; followed by heating to 50 to 70° C. to achieve complete dissolution; cooling the solution to room temperature; and adding an anti-solvent to the resulting solution to cause precipitation of crystals. The crystals are allowed to grow at a constant temperature for 10 to 60 minutes, so as to give a slurry containing the crystals. Said slurry is subjected to filtration and then drying to obtain the crystalline form of phenyl bis (2,4,6-trimethylbenzoyl) phosphine oxide.Type: GrantFiled: January 8, 2021Date of Patent: September 12, 2023Assignee: Tianjin UniversityInventors: Ying Bao, Pei Zhao, Mingshuo Chen, Baohong Hou, Chuang Xie, Lina Zhou
