Document Type and Number:
Japanese Patent JP2639434
Kind Code:
B2
Abstract:
PURPOSE:To obtain a surfactant of desired purity by an efficient reaction by carrying out electrodialysis with an ion exchange membrane obtd. by treating the surface of a sulfonic acid type cation exchange membrane having a specified ion exchange capacity and a specified water content with an amine-aldehyde condensation product. CONSTITUTION:When an alkali metal salt of an amino acid or acylated amino acid type surfactant is electrodialyzed in the presence of a mineral acid salt of alkanolamine or ammonia to produce the alkanolammonium or ammonium salt of the amino acid or acylated amino acid type surfactant, the electrodialysis is carried out with a sulfonic acid type cation exchange membrane obtd. by treating the surface or surface layer of a cation exchange resin with an amine- aldehyde condensation product to regulate the ion exchange capacity to 2.0-3.0 milliequiv. per 1g dry resin and the water content to 0.2-0.3%. The desired ammonium salt of high purity can be efficiently produced.
