Title: Process for the manufacture of 3-hydroxythionaphthene-7-carboxylic acid chlorides and carboxylic acids
Filed: 1931-05-11
Abstract: 3-Hydroxythionaphthene-7-carboxylic acid chloride and nuclear substitution products thereof are manufactured by treating the di-acid chloride of phenyl-1-thioglycollic-2-carboxylic acid or a nuclear substitution product thereof, in which the 6-position is unsubstituted, with an acid condensing agent.  The corresponding carboxylic acids are obtained by saponifying the acid chlorides. In examples: (1) phenyl-1-thioglycollic-2-carboxylic acid is converted into its di-acid chloride by the action of phosphorus trichloride and the product is treated with aluminium chloride to produce 3-hydroxythionaphthene-7-carboxylic acid chloride, which is saponified to the acid; when a solution of this product in sodium carbonate solution is allowed to stand in the air, thioindigo-7 : 7<1>-dicarboxylic acid is produced; (2) 5-chlorophenyl-1-thioglycollic-2-carboxylic acid is treated with thionyl chloride and the di-acid chloride produced is converted by the action of aluminium chloride and subsequent saponification into 4-chloro-3-hydroxythionaphthene-7-carboxylic acid; the product, on oxidation in alkaline solution with potassium ferricyanide, yields 4 : 4<1>-dichlorothioindigo-7 : 7<1>-dicarboxylic acid.  The preparation of 3-hydroxythionaphthene-7-carboxylic acids containing methyl groups in the nucleus also is referred to.

Patent GB-374597-A (GB)
Title: Improvements in the reactivation of adsorbents
IPC: C01B31/08
Filed: 1931-05-12
Abstract: Reactivation of adsorbents, such as active charcoal or silica gel, which have been rendered inactive, e.g. by resinous substances, during adsorption of hydrocarbons from gases, is effected by hydrogenation at elevated temperatures and pressures, preferably in the presence of a catalyst in the form of a compound of vanadium, chromium, tungsten, iron or uranium.  In some cases the hydrogenation may be effected at atmospheric pressure.  The catalyst may be applied during the preparation of the adsorbent, e.g. during activation or granulation in the form of oxide or carbonate, or the activated material may be sprayed with a solution of the catalyst, e.g. with a solution of ammonium vanadate, chromate, tungstate or uranate, chromic acid or iron oxalate.  In an example, fouled active carbon used for the recovery of benzole, a mixture of benzene with other aromatic hydrocarbons, from coal gas is first treated to remove the benzole and then with a solution of ammonium vanadate in water, after which it is heated in the presence of hydrogen at 440-450 DEG  C. at 250 to 280 atmospheres, the pressure being released while hot. The treatment for the removal of the benzol may be omitted and the light hydrocarbons formed from the resinous materials may be recovered. Specification 332,336, [Class 32, Distilling &c.], is referred to.
