| titleOfInvention | Continuous production method of high-purity phosphate ester salt |
| abstract | (57) [Summary] [Object] The present invention provides a method for producing a high-purity phosphate ester salt. A composition comprising a mixed solution containing a phosphate ester salt and a nonionic compound, a straight or branched chain aliphatic hydrocarbon having 4 to 8 carbon atoms and a saturated alicyclic hydrocarbon having 5 to 7 carbon atoms. When one or more solvents (a) selected from the above are continuously countercurrently contacted using an extractor to extract and separate the nonionic compound into the solvent layer, a lower alcohol having 1 to 4 carbon atoms ( b) Is supplied to the mixed solution and the solvent (a) to be supplied to the extractor, and a continuous process for producing a high-purity phosphate ester salt. [Effects] According to the present invention, a large amount of lower alcohol was required in the conventional demulsification, but it becomes possible to demulsify with a small amount of lower alcohol, and since the demulsification is quick, the apparatus can be made compact, and The amount of solvent used as an extractant can be significantly reduced, and the extraction efficiency can be improved. In particular, the present invention is effective when the mixed liquid is in an emulsified state containing a solvent, and the extraction efficiency can be improved. |
