| titleOfInvention | Method for decolorizing sodium glycinate |
| abstract | PURPOSE: To readily decolorize sodium glycinate without lowering purity of sodium glycinate or increasing impurities, by subjecting a colored sodium glycinate solution to contact treatment using an oxidant such as oxygen or hydrogen peroxide. n CONSTITUTION: An aqueous solution of sodium glycinate obtained by hydrolyzing glycinonitrile obtained by synthesizing glycolonitrile from prussic acid and formaldehyde and then aminating the resultant glycolonitrile with ammonia, etc., with an alkali such as NaOH is readily decolorized by subjecting the aqueous solution of sodium glycinate to contact treatment with an oxidant (especially preferably air, oxygen enriched air, oxygen-diluted air or hydrogen peroxide). According to the above-mentioned method, sodium glycinate can be readily decolorized by a simple method without using a large amount of expensive treating agent. n COPYRIGHT: (C)1989,JPO&Japio |
