Abstract

14,943. Johnson, J. Y., [Badische Anilin & Sodu Fabrik]. June 26. Indole is produced by heating indoxyl or its carboxylic acid with caustic alkali, mixed or not with caustic alkaline-earth and water at a temperature of about 150‹ C. and upwards. Specification 6419/03 is referred to. The Provisional Specification describes the use of basic agents generally.
