METHOD OF MANUFACTURING QUATERNARY SALT SOLUTION |
摘要 |
PROBLEM TO BE SOLVED: To provide a method of industrially efficiently manufacturing a solution where low moisture quaternary salt is dissolved into a specific solvent without special facilities.SOLUTION: The method of manufacturing includes the following processes 1 to 3. Process 1: A process of alkylating amines and/or phosphines in a solvent (b1) having a boiling point of 35 to 260°C to obtaining a solution (S1) of a quaternary ammonium salt and/or a quaternary phosphonium salt (a1), then conducting an acid exchange treatment of (S1) with an inorganic acid aqueous solution or an organic acid aqueous solution to obtain a solution (S2) of a quaternary salt (a2). Process 2: A process of removing the solvent (b1) and water in (S2) to obtain a quaternary salt solution (S3) having a concentration of 50 to 90 wt.%. Process 3: A process of removing the solvent (b1) and water after adding a solvent (b2) having a boiling point of 101 to 300°C and higher than the boiling point of the solvent (b1) for dissolving the quaternary salt (a2) to obtain a quaternary salt solution (S). |
