Hexa-substituted guanidinium chloride aqueous solution and its preparation and use |
| abstract |
(57) Abstract: A hexasubstituted guanidinium chloride aqueous solution, its preparation method and its use method are provided. A novel method for preparing hexasubstituted guanidinium chloride is provided by which the hexasubstituted guanidinium chloride is provided in high yield as an aqueous solution optionally also containing an alkali metal chloride. To be done. This solution can be used as a source of a hexasubstituted guanidinium salt which is useful as a phase transfer catalyst in a reaction of forming a polyetherimide or an intermediate thereof with an alkali metal salt of a dihydroxy aromatic compound and a substituted imide. |
