VERFAHREN ZUR REINIGUNG VON TRYPTOPHAN, DESSEN IM RING SUBSTITUIERTEN DERIVATEN UND DESSEN N-ACYL-DERIVATEN

Tryptophane and tryptophane derivatives are purified by treating them in an inert solvent at a temperature between about 20 DEG C. and the boiling point of the mixture with a salt of dithionous acid. Preferably there is used as solvent a mixture of water and a lower aliphatic carboxylic acid. Normal...

Zusammenfassung:Tryptophane and tryptophane derivatives are purified by treating them in an inert solvent at a temperature between about 20 DEG C. and the boiling point of the mixture with a salt of dithionous acid. Preferably there is used as solvent a mixture of water and a lower aliphatic carboxylic acid. Normally a single treatment results in a pure, colorless, satisfactory product.
