Abstract

15,223. Imray, O., [Basle Chemical Works]. July 7. Dyes, artificial.-Indoxyl derivatives are formed from arylglycines or their derivatives by the addition to the ingredients described in Specification No. 26,061, A D. 1901, of alcohol. In an example, alcohol vapour is fed into a heated mixture of sodium, phenylglycine potassium salt, and caustic alkali, by the aid of a current of hydrogen. The alcohol may however be used in the liquid form. The Provisional Specification mentions the use of arylglycine anilides or glycides, and a-arylhydantoins.
