Title: Process for the manufacture of organic compounds containing fluorine
IPC: C07B39/00
Filed: 1935-02-26
Abstract: <PICT:0452656/IV/1> Organic compounds containing fluorine are prepared in good yield and in a smooth manner by allowing fluorine which is substantially free from oxygen and oxides of fluorine to react in a finely distributed state upon the organic compounds. Fluorine of the required degree of purity can be prepared by electrolyzing a melt of potassium bifluoride which is substantially free from water, preferably having a water content below 0,05 per cent. The distribution of the fluorine is effected by the use of solid filling materials such as iron, copper, silver and cerium arranged in the form of coils, wire nets, sponges, grains, &c.  Two forms of apparatus are described which effect a fine distribution of the fluorine and allow the materials to interact in small gas spaces. For example, in apparatus as shown, the liquid to be fluorinated enters through valve n into the reaction chamber k filled with packing material.  Fluorine enters through ducts s and inlet tubes i provided with bore holes and surrounded by packings r of inert material.  The reaction product is drawn off at v.  It is preferred to conduct the reaction in the gaseous phase, but in the case of difficulty volatile materials the reaction can be conducted in solution in an inert solvent such as carbon tetrachloride.  In examples: (1) this example shows that carbon tetrachloride is inert to fluorine under the conditions of the invention, whereas under ordinary conditions it reacts with explosion; (2) fluorine is introduced into a -a -diphenylethylene to yield a -a -diphenyl-a -b -difluoroethylene in an amount equivalent to 85 per cent of the theoretical; (3) fluorine is passed into petroleum to give a product having a fluorine content of 9,8 per cent which represents a yield of 95 per cent; (4) fluorine is passed into a solution of cumarin in carbon tetrachloride to give a product having a fluorine content of 19,5 per cent.

Title: Improvements in and relating to electron discharge devices
IPC: H01J17/54
Filed: 1929-02-25
Abstract: 309,442. British Thomson-Houston Co., Ltd., (Assignees of Hull, A. W.). April 10, 1928, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-A discharge device containing a gas or metallic vapour at a pressure sufficiently high to pass a discharge having an arc-like or negative current-voltage characteristic, has an anode, a thermionic cathode, and control grid in the form of a perforated sheet-metal cap closely surrounding the cathode so that the cathode is shielded electrostatically from the walls of the envelope and that the discharge must pass through the grid. In such a device a sufficiently high negative potential on the grid prevents the starting of a discharge, but a positive potential allows current to pass, and, after the establishment of the discharge, the grid potential has no effect; the resulting ionization neutralizes the space charge completely and the device will operate with a voltage between the anode and cathode lower than the ionization voltage of the gas. The grid 4, Fig. 1, is supported on a collar 24. The anode 3 is in the form of a disc of graphite or nickel arranged axially of the cylindrical cathode 2. A disc 27 of nickel may be mounted on the stem 13 so as to shield the base of the envelope from heat radiated from the cathode 2. As shown in Fig. 2, the cathode consists of an enclosure 5 of nickel or iron containing a helical tungsten heater 7 and an insulating lining 8 of alumina or thoria. A cylinder 13, polished on the outside, is connected by vanes 6 with the cathode, and serves to reduce radiation of heat from the cathode. The circuit of the cathode and heater is completed by a lead 9 to the heater and leads 11 to the cylinder. The vanes and interior of the cylinder 13 are coated with electron-emitting material, such as a rare earth metal, an alkaline earth metal, or a compound of an alkaline earth metal, for example barium carbonate which is reduced subsequently by heating nearly to the melting point of nickel. The filling consists of argon or mercury vapour at a pressure of 10 microns. The anode is connected with the cathode through a load such as a relay winding 26, a generator 32 of alternating current, and the primary 35 of a transformer. A control device such as a photo-electric cell 40 is connected between the anode and the grid, which is also connected with the secondary 37 through a high resistance 38 and condenser 39 in parallel. The heating circuit for the cathode is supplied from a part of the secondary.

Title: Process for the manufacture of new hydroxamic acid derivatives
Filed: 1942-05-11
Abstract: A hydroxamic acid which contains a basic group or at least 8 carbon atoms in an aliphatic or cycloaliphatic residue is treated with an acylating agent capable of introducing the residue of a carboxylic or sulphonic acid.  The latter may contain halogen, which may be exchanged for a quaternary ammonium group, an isothiourea resudue in salt form or a neutralised thiosulphuric acid residue so as to render the product soluble in water.  Groups which render the products soluble may be already present in the acylating agents.  In a modification, a hydroxamic acid containing halogen may be used as starting material.  It is first acylated and then the halogen is exchanged for a basic group.  For the acylation, carboxylic or sulphonic acids or their functional derivatives are employed. Examples of such agents are: maleic anhydride, succinic anhydride, phthalic anhydride, sulphoacetic acid, sulphochloracetic acid, sulphosuccinic acid, sulphophthalic anhydride, 3 : 5-disulphophthalic anhydride, benzoylchloride-3 : 5-disulphonic acid and chloracetic acid.  The products may be used as wetting, levelling, emulsifying and washing agents in the textile and leather industries.  The high molecular products, when applied to cellulose, regenerated cellulose, wool or silk fabrics and subjected to a heat treatment render them water repellent. Products containing a basic group improve the fastness of cellulose dyed with acid dyes, and may be used for animalising cellulose.  Salts of weak acids, alkali hydroxides, paraffin wax, methylol compounds of higher fatty acid amides, thioureas, aminothiazines and synthetic resins may be used in conjunction with the products for the treatment of textiles so as to increase the hydrophobic and anticrease properties of the latter.  In examples: (1) lauric or stearic hydroxamic acid is acylated with acetic anhydride; (2) stearichydroxamic acid is treated with benzoic acid meta-sulphochloride or para - chlormethylbenzoylchloride in the presence of pyridine; (3) 4-chlormethylbenzoyl-chloride is condensed with hydroxylamine-hydrochloride and the resulting 4-chlormethylbenzhydroxamic acid first reacted with trimethylamine and then acylated with acetic anhydride; (4) a mixture of palmitic and stearic hydroxamic acids is treated with chloracetylchloride in dioxane and the product made soluble by treating with sodium thiosulphate in methanol or with thiourea in acetone; (5) cotton fabric is treated with a solution containing acetone, caustic soda and the acetylated stearic hydroxamic acid of example (1); (6) cotton material is treated with products obtained as in examples (2) and (3).  The hydroxamic acids may be derived from aliphatic, aliphatic aromatic, aromatic and cycloaliphatic carboxylic acids and may be prepared by known methods.  Thus, stearic acid methyl ester may be reacted with hydroxylaminic hydrochloride to give stearic hydroxamic acid and parastearylaminobenzoylchloride may be reacted with hydroxylamine to give the corresponding hydroxamic acid.
