ABSTRACT:
A novel process for preparing an alkanolammonium salt or ammonium salt of an amino acid surface active agent or an acylated amino acid surface active agent. In the process, an alkali metal salt of an amino acid surface active agent or acylated amino acid surface active agent is subjected to electrodialysis in the presence of a mineral acid salt of an alkanolamine or ammonia, or a mixture of an alkanolamine or ammonia and a mineral acid.
By-products which are produced during the preparation of the above surface active agents can be mostly removed to outside during the electrodialysis and are thus purified conveniently.
