Title: Process for the production of organic amino diol derivatives
Filed: 1951-07-30
Abstract: 1 - Nitrophenyl - 2 - aminopropane - 1 : 3 - diol derivatives of the general formula <FORM:0697697/IV (b)/1> (wherein R represents hydrogen or an acyl radical and R3 represents hydrogen, halogen or an alkyl or alkoxy radical of 1-4 carbon atoms) are manufactured by selectively reducing with a complex hydride of lithium the free and/or esterified carboxyl groups in a nitrophenylserine derivative of the general formula <FORM:0697697/IV (b)/2> (wherein R1 represents hydrogen or an acyl radical, and may be the same as or different from R, and R2 represents hydrogen, an alkyl radical of 1-4 carbon atoms, a phenyl or a phenalkyl radical).  The term "acyl" comprises saturated or unsaturated aliphatic and hydroxy-, ether- or halogen-substituted aliphatic acyl radicals of 1-4 carbon atoms, benzoyl and halogen, nitro, alkyl or alkoxy substituted benzoyl radicals, and araliphatic acyl radicals.  The reduction is advantageously effected with lithium aluminium hydride in an anhydrous non-hydroxylic solvent (e.g. diethyl or dibutyl ether, dioxane, tetrahydrofurane, or ethylene glycol dimethyl or diethyl ether), the reducing agent preferably being used in an amount between 10 per cent less and 10 per cent more than (but, if desired, up to 35 per cent more than) the theoretical quantity, which depends on the nature of the groups present in the starting material and is calculated as follows: 0.75 mol. for a free carboxyl group, 0.5 mol. for an ester group, 0.25 mol. for a hydroxy group and 0.5 mol. for an amino group.  After the reduction the metal complex formed is decomposed with water, the amount of which should be at least 4 mols per mol. of lithium aluminium hydride used.  Examples describe the reduction of: (1) (a) ethyl l-#Y-N-dichloro- or -dibromo-acetyl-p-nitrophenylserinate; (b) l-#Y-N-dichloroacetyl-O-acetyl-p-nitrophenylserine or its methyl ester; (c) l-#Y-N-dichloroacetyl-p-nitrophenylserine; (2) (a) ethyl dl - #Y - N - dichloroacetyl - p - nitrophenylserinate; (b) methyl dl-#Y-N-dichloroacetyl-O-benzoyl-p-nitrophenylserinate; (3) ethyl l-#Y-p-nitrophenylserinate; (4) methyl or phenyl dl-#Y-p-nitrophenylserinate; (5) ethyl dl- or l-#Y-O,N-diacetyl-p-nitrophenylserinate; (6) ethyl dl-#Y-N-benzoyl-p-nitrophenylserinate; (7) methyl dl - reg. - N - p - methylbenzoyl - 3 - methyl-2 - ethoxy - 5 - nitrophenylserinate; (8) benzyl dl - reg. - N - p - methylbenzoyl - 3 - methyl - 4 - nitrophenylserinate; (9) methyl dl-#Y-N-phenylacetyl - 2 - nitro - 4 - chlorophenyl-serinate.

Title: Method of manufacturing cathodes for electron tubes
IPC: H01J9/04
Filed: 1964-04-30
Abstract: 1,057,909. Making cathodes; destructible cores. MATSUSHITA ELECTRONICS CORPORATION. April 30, 1964 [April 30, 1963], No. 18036/64. Headings B3A and B3E. [Also in Division H1] A method of making a cathode element for electron tubes such as miniwatt cathode-ray tubes comprises coiling a heating filament of for example tungsten about a mandrel of soluble metal, for example molybdenum, flattening the filament and the mandrel providing an insulating layer on at least one surface of the element and dissolving away the mandrel. The element is trimmed to form terminals 8 and coated with an electron emissive oxide layer 10 by spraying, electro-deposition or immersion to form a directly heated cathode, Fig. 4. To provide the insulating layer the flattened assembly is placed in a mould 11, Fig. 5 (not shown), preferably of molybdenum which is filled from alternate sides with insulating paste of e.g. aluminium oxide with distilled water or a nitrocellulose solution and heated to 1600/ 1700‹ C. in hydrogen. Alternatively a flattened assembly is embedded in powdered aluminium oxide between dies, Fig. 9 (not shown). After removal from the mould, the ends are shaped and the flattened mandrel dissolved away. An indirectly heated cathode is formed by inserting an insulated element 21 into a nickel sleeve 22, Fig. 10 (not shown), with an insulating layer 24 of e.g. aluminium oxide therebetween and providing an emissive oxide layer 26 on the outer sleeve 22. The layer 24 may be obtained by immersing one end of the assembly into an insulating solution so that capillary action fills the space 23 and finally drying the assembly. Alternatively the sleeve 22 may be pressed about the element 21 in dies, Fig. 11 (not shown). One or both sides of the insulating material may be directly coated with a layer of electron emissive oxide or with a thin metal sheet which is subsequently oxidized.

Patent GB-421596-A (GB)
Title: Improvements in the manufacture and production of alkyl derivatives of ammonia
IPC: C07C209/18
Filed: 1933-06-24
Abstract: N-Alkyl derivatives of ammonia are manufactured by treating ammonia or primary or secondary amines at elevated temperatures, e.g. 150--450 DEG  C., preferably 200--400 DEG  C., and superatmospheric pressures, e.g. at least 10 atmospheres, in the presence of catalysts promoting the splitting off of water, e.g. alumina gel, peptized or ordinary aluminium oxide, thorium oxide, silica gel or mixtures thereof, with an ether containing at least one alkyl group having at least two carbon atoms.  The ethers may be symmetrical or mixed, and the second hydrocarbon group may be an aromatic or another alkyl group; in the latter case, mixtures of the alkyl derivatives corresponding to the alkyl groups of the ethers are usually formed. It is advantageous, especially when working in a cycle, to add the undesirable decomposition products which are sometimes formed, e.g. olefines, or to allow the mixture to become enriched therein, in order to suppress their formation. In examples: (1) aniline and diethyl ether, with or without ethylene, are led over peptized aluminium oxide at 150 atmospheres and 320 DEG  C., producing N-mono- and -diethylaniline; the diethyl ether may be replaced by dibutyl ether; (2) a mixture of N-mono- and diethylaniline is treated with diethyl ether under the conditions of (1), the proportion of diethylaniline being thereby increased; (3) the reaction of (1) is carried out at 20 atmospheres and, for purposes of comparison, at atmospheric pressure; (4) o-toluidine and diethyl ether are passed over peptized aluminium oxide at 325 DEG  C. and 20 atmospheres to produce N-mono- and -diethyl-o-toluidine; (5) o-toluidine and dibutyl ether are treated as in (4) but at 25 atmospheres, yielding N-mono- and -dibutyl-o-toluidine; (6) aniline and dibutyl ether are passed over peptized aluminium oxide or thorium oxide at 325 DEG  C. and 30 atmospheres to produce N-mono- and -dibutylaniline; (7) aniline and ethyl butyl ether are passed over peptized aluminium oxide at 330 DEG C. and 20 atmospheres, producing N-mono- and -diethyl- and -mono- and -dibutylaniline; (8) ammonia and diethyl ether are passed over aluminium oxide at 350 DEG  C. and 20 atmospheres, yielding mono-, di- and triethylamines, which are absorbed in sulphuric acid; if the mixture of amines liberated from the sulphuric acid solution is again treated with diethyl ether it is enriched in diethylamine; (9) aniline and diethyl ether are passed over aluminium oxide at 350 DEG C. and 20 atmospheres to produce N-mono- and -diethylaniline. Specification 319,205, [Class 2 (iii)], is referred to.
