Title: Improvements in the synthesis of ammonia
IPC: C01C1/04
Filed: 1927-12-28
Abstract: 272,930. Uhde, G. F. Dec. 28,1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 16, 1927.] Ammonia, catalytic production of from nitrogen and hydrogen.-In the synthesis of ammonia with the use of catalysts comprising decomposition products of complex cyanides, the catalysts are prepared for use by passing through the initial material, in the contact furnace itself, a hydrogen-containing gas mixture, free from oxygen or oxygenated compounds, which has been heated externally of the furnace. The gas mixture may comprise initially a hydrogen-nitrogen mixture containing only 10 per cent or so of hydrogen, but as the preparation of the catalyst proceeds, the hydrogen content of the mixture and its temperature and pressure are raised until the necessary conditions for the synthesis are reached. The provision of heating means for the contact furnace is unnecessarry, since if the reaction is not self-supporting, the heating means for the gas mixture can be brought into play.

Title: Improvements in and relating to the production of anthracene derivatives
IPC: C09B9/02
Filed: 1931-06-01
Abstract: Indanthrone derivatives; vat dyes, dyeing with; printing.--Disulphuric esters of tetrahydrodianthraquinoneazines are obtained by treating tetrasulphuric esters of tetrahydrodianthraquinoneazine or -dihydroazine or their substitution products with oxidizing agents, the treatment of tetrahydrodianthraquinoneazine tetrasulphuric ester with sodium hypochlorite and carbon dioxide (Specification 359,889) being excluded.  The products obtained are usually mixtures of isomers, which may be separated by fractional salting out.  On treatment with cold dilute mineral acids, they are converted into monosulphuric esters of anthraquinoneanthrahydroquinonedihydroazines; further treatment with hot mineral acids leads to the production of leucoindanthrones.  The products may be used for dyeing and printing, the colours being developed by heating with dilute mineral baths, the addition of oxidizing agents being unnecessary. In examples (1) the potassium salt of the tetrasulphuric ester of tetrahydrodianthraquinoneazine is treated with boric acid and sodium hypochlorite or with chlorine in the presence of sodium bicarbonate; the product consists of a mixture of two of the isomeric disulphuric esters of tetrahydrodianthraquinoneazine, containing the ester groups in different anthraquinone nuclei, together with a little of the disulphuric ester of dihydrodianthraquinoneazine, containing both ester groups in the same anthraquinone nucleus, described in Specification 359,889, (2) the product of the previous example is separated into its three components by salting out with sodium and potassium chloride, (3) the mixture of isomeric disulphuric esters is treated with cold hydrochloric acid, and the monosulphuric esters obtained are separated into a less soluble violet component and a more soluble red component by fractional crystallization, (4) cotton is padded with a bath containing the product of example (1), dried and developed in a warm bath containing sodium chloride and sulphuric acid, and (5) cloth is printed with a paste containing the product of example 1, glycerine and British gum, steamed or dried, and developed.
