| titleOfInvention | Method for purifying metal aminoethylsulfonate |
| abstract | PURPOSE: To effectively decolor and economically and readily purify the subject compound useful as dyeing assistants, agricultural chemicals, etc., by bringing a crude reaction solution obtained by reacting a metallic salt of isethionic acid with ammonia, etc., into contact with amorphous carbon. n CONSTITUTION: A metallic salt of isethionic acid is allowed to react with ammonia or a monoalkylamine to provide a metal aminoethylsulfonate expressed by the formula (M is alkali metal or alkaline earth metal; R is H or alkyl), which is then purified. In the process, the reaction solution containing the aforementioned metallic salt is brought into contact with amorphous carbon (especially preferably active carbon). The contact treatment temperature is normally ≥20°C, preferably 30-50°C. The concentration of the metal aminoethylsulfonate in the solution to be treated and brought into contact with the amorphous carbon is preferably 5-65wt.%. The amorphous carbon adsorbing coloring components can be desorbed and regenerated with hydrochloric acid, etc., for reuse. n COPYRIGHT: (C)1992,JPO&Japio |
