Patent number: 11919976Abstract: The present invention relates to a preparation and purification method for cationic quaternary ammonium salt of sodium hyaluronate in homogeneous medium. By adding a homogeneous solvent and a sodium hyaluronate solid to a vessel, heating the vessel until the contents are dissolved to form a homogeneous system, adding an aqueous solution of 2,3-epoxypropyltrimethylammonium chloride (GTA) to the homogeneous system, then adding a base catalyst, and stirring at a preset temperature to carry out a graft reaction, a graft product is obtained wherein 2,3-epoxypropyltrimethylammonium chloride is grafted to the oxygen atom of the hydroxymethyl group of sodium hyaluronate. By using the method, a graft product wherein 2,3-epoxypropyltrimethylammonium chloride is grafted to the oxygen atom of the hydroxymethyl group of sodium hyaluronate is obtained. Addition of salts is avoided during the reaction, a grafting yield up to 0.69 is obtained, and coagulation occurred to the product is effectively solved.Type: GrantFiled: April 11, 2023Date of Patent: March 5, 2024Assignee: SHANDONG FOCUSFREDA BIOTECH CO., LTDInventors: Jinmao You, Lei Liu, Chuanli Kang, Shuiqiang Yu, Deqiang Zheng, Qing Li, Shuai Du, Xinxin Shi, Qiang Liu, Liwei Tang, Shaojie Lian, Meixia Zhang
