Title: Improvements in or connected with the Manufacture of Products and Colouring-matters related to the Indigo-group.
Inventor: JOHNSON JAMES YATE
Filed: 1898-10-25
Granted: 1899-08-26
Abstract: 22,459. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Oct. 25. Isatin and its homologues; isatinic acid; dyes, artificial.-Relates to modifications of the processes described in Specifications Nos. 8726 and 10,509, A.D. 1890, and consists in producing thereby isatin and isatinic acid and their homologues, and indigo reds. (1) Sodium phenylglycocoll-o-carboxylate, or phenylglycocoll itself, or its homologues or analogues, are heated at 260‹-270‹ C. with caustic soda, freed as far as possible from water, the mixture being in the form of a fine loose powder containing a limited quantity of acid which takes part in the reaction. The mixture is dissolved m water, air is passed through the solution to oxidize any indigo leuco compound, the ind go precipitated is filtered off, and the mother liquor containing the sodium salt of isatinic acid is concentrated at a low temperature, preferably in vacuo. The salt separates, and it may be used as such, or it may be converted into isatin in the usual manner. (2) The indoxylic acid contained in the aforesaid melt, or obtained from other sources, is converted into the corresponding isatin compound by energetic oxidation in acid, neutral, or alkaline solution. Examples are given in which isatin is produced by oxidizing an alkaline melt containing indoxylic acid by means of nitric acid in presence of acetic acid ; by oxidizing indoxylic acid by means of potassium permanganate and caustic soda ; by oxidizing #-naphthindoxylic acid ethylester by potassium ferricyanide and caustic soda; and by oxidizing indoxyl by manganese peroxide and caustic soda and by oxidizing indoxylic acid by cupric sulphate and caustic soda. (3) Indigo - red colouring matters, or analogues thereof, are produced by means of the isatin compounds obtained by the foregoing processes. For example, the mother liquor obtained by filtering off the precipitated indigo as described in (1) is neutralized with sulphuric acid and heated with a further quantity of the original melt. The mixture is made alkaline and boiled as long as indigo-red precipitates. In another example, the solution containing isatin, obtained by oxidation of indoxylic acid, is heated with indoxylic acid, or indoxyl, and acetic acid. The mixture is filtered hot and acidified with hydrochloric acid, whereby indigo-red is precipitated.

Title: Improvements in the Manufacture and Production of Colouring-matters containing Sulphur.
Filed: 1899-09-15
Granted: 1900-07-28
Abstract: 18,658. Green, A. G., Meyenberg, A., and Clayton Aniline Co. Sept. 15. Dyes, artificial.-Dyes which contain sulphur and dye cotton fast dark shades direct from a sodium-sulphide bath, are produced by oxidation in presence of thiosulphuric acid of an o-diamine, o - amidophenol, or o - dihydroxybenzene, or of amidated, hydroxylated, or other substitution derivatives thereof, such as triamidobenzene, triamidotoluene, tetramidobenzene, diamidophenol, and the like, whereby a thiosulphonic acid is first formed, and by further oxidation of this intermediate product and subsequent heating in acid solution. A second component, such as a phenol, amine, diamine, or amidophenol, or one of the above-mentioned parent compounds, may be used in the further oxidation process. The oxidation is effected by means of sulphuric acid and sodium bichromate, the amount of oxygen necessary varying with the proportion of thiosulphuric acid, the nature of the ortho compound employed, and the shade it is desired to produce. An example is given in which o-phenylenediamine is converted into a dye which separates after the final boiling with acid, and is used in a sodium-sulphide bath for producing on unmordanted cotton full brown shades of considerable fastness against washing. The fastness is increased and the shade darkened by passing the dyed goods through a bath of a copper salt, or a bichromate.
