Patent GB-581931-A (GB)
Title: Improved method of manufacturing chlorine dioxide
IPC: C01B11/02
Filed: 1944-01-05
Abstract: Chlorine dioxide is produced by reducing a metal chlorate in aqueous solution above 70 DEG C, preferably at 90 DEG C, with a primary agent having a normal Oxidation Reduction potential of +1 to +1.6, preferably +1 to +1.3 volts, regenerating the primary agent bedow 40 DEG C, preferably at 20 DEG C, with a secondary reducing agent having an Oxidation Reduction potential below +1 volts, adding fresh chlorate and recycling the solution.  According to a modification, the two steps may proceed simultaneously at the same temperature, e.g., 60-100 DEG C.  As primary agents, water soluble mixtures of 3 and 6 valent chromium or 1 and 3 valent thallium compounds are preferred, though arsenic, antimony, bismuth or ferrous compounds may be used.  Sulphur dioxide, which provides necessary acid, is preferred for the secondary reduction but sulphur, hydrogen sulphide, sulphides, divalent sulphur compounds, or cathodic reduction may be used.  The two reactions are preferably controlled so that not more than 95 per cent. of the primary reducing agent is in either the oxidised or reduced form, thus ensuring a buffer action which prevents reduction of chlorate or chlorine dioxide to chloride by the secondary reagent and oxidation of chloride to chlorine by the chlorate.  Preferably the chlorine dioxide is continuously removed by a stream of inert gas, and the metal salt produced removed before recycling.  The Specification as open to inspection under Sect. 91 comprises also the use of carbon or carbon monoxide as secondary agents. This subject-matter does not appear in the Specification as accepted.
Patent GB-566732-A (GB)
Title: Manufacture of substituted arylene dioxane compounds
IPC: C07D319/20
Filed: 1943-01-06
Abstract: Substituted arylene dioxane compounds are prepared by reacting an arylene dioxane or a derivative thereof with formaldehyde and a hydrogen halide and then reacting the intermediate product containing a halogen methyl group in the aromatic nucleus with a primary or a secondary amine.  In those cases where the arylene dioxane already contains a phenolic group, the formaldehyde and the amine or the hydroxymethylalkylamine resulting from these compounds may be allowed to react directly on the phenolic starting product.  According to the invention, it is also possible to produce polyaminomethyl compounds in which both the aromatic nucleus and the hetero-ring are linked through methyl groups to amino and alkylamino groups.  In examples: (1) benzodioxane is treated with formaldehyde and hydrochloric acid in the presence of zinc chloride and petroleum ether to form ar-chloromethyl-benzodioxane.  This is reacted with piperidine in benzene solution to give ar-piperidino-methyl-benzodioxane; (2) ar - chloromethyl - benzodioxane is treated with diethylamine as in example (1) to form diethylaminomethyl-benzodioxane; (3) ar - chloromethyl - benzodioxane is treated with morpholin as in example (1) to form ar - morpholenylmethyl - benzodioxane. Instead of the non-substituted benzodioxane, there may also be used o-methyl, propyl and o-methoxy derivatives; (4) 2-morpholinylmethyl-benzodioxane hydrochloride prepared according to Specification 565,982 is treated with formaldehyde and hydrochloric acid as in example (1) followed by treatment with diethylamine to yield 2-morpholinyl-methyl-ar-diethylamino-methyl-benzodioxane.  The isomeric compound may be obtained by the same procedure starting with 2-diethylaminomethyl-benzodioxane and treating it with formaldehyde and hydrochloric acid followed by morpholin; (5) 2-morpholinylmethyl-benzodioxane is treated as in example (1) with formaldehyde, zinc chloride and hydrochloric acid, followed by over-neutralization with morpholin to form 2-ar-bis-(morpholinylmethyl) benzodioxane; (6) 2 - butylaminomethyl - o - methoxybenzodioxane produced according to Specification 565,573 is treated with formaldehyde, zinc chloride and hydrochloric acid as in example (1), followed by diethylamine to give 2 - butylaminomethyl - o - methoxy - ar - diethylaminomethyl - benzo - 1 : 4 - dioxane hydrochloride; (7) 2 - morpholinylmethyl - hydroxybenzodioxane produced according to Specification 565,573 is treated with formaldehyde in alcohol solution diethylamine added, followed by hydrochloric acid to form 2-morpholinylbenzo-1 : 4-dioxane; (8) nitrobenzodioxane is reduced with iron and acetic acid to the amino compound which is then diazotized and hydrolysed.  The hydroxybenzodioxane so produced is treated with formaldehyde and morpholin in alcohol solution followed by hydrochloric acid to produce ar - hydroxy - ar - p - oxazinylmethyl-benzo-1 : 4-dioxane.

Title: Improvements in or relating to electric cables
IPC: H01B13/30
Filed: 1939-01-04
Abstract: 519.602. Electric cables. SOC. ITALIANA PIRELLI. Jan. 4, 1939, No. 252. Convention date, Feb. 10, 1938. [Class 36] [Also in Group VIII] In the manufacture of an electric cable of constant volume type having an oil impregnated insulation so as automatically to maintain the internal pressure at a predetermined value which is substantially constant and determined by the applied voltage, said value being sufficiently high to prevent ionizing at normal working conditions of the cable, the impregnation is effected with a gasogenic oil such that, in the state of vapour, it automatically develops gas under the action of the electric field if the internal pressure falls below said predetermined value, and thus restores the pressure to said value. The most volatile components of the oil preferably comprise mainly saturated hydrocarbons of the aliphatic series with branch chain molecules. Substances such as iso-octanes, iso-nonanes or their homologues may be added to increase the gasogenicity. The manufacture of the cable is effected so that the insulation contains inc1usions of gas from the time of its manufacture.
