Title: Manufacture of nitro compounds
IPC: C07C205/02
Filed: 1944-01-19
Abstract: Nitro compounds of the formula RR1R2C-CHR3-NO2, wherein R, R1 and R2 may be hydrogen or substituted or unsubstituted aliphatic, cycloaliphatic or heterocyclic radical or either R or R1 together with R3 may form a cycloaliphatic ring and R2 is a substituted or unsubstituted aliphatic, cycloaliphatic or aromatic hydrocarbon radical, are prepared by reacting a D a -nitro-olefine of the formula RR1C=CR3-NO2 with an organometal halide R2MX, M representing magnesium or zinc atoms and X a halogen atom, and thereafter treating the reaction product with water or an aqueous acid.  The reaction may be brought about by mixing solutions, for example, ethereal solutions, of the two reactants at a low temperature, for example, in the region of 0 DEG  C. and subsequently heating the solution to a suitable temperature such as the boiling point of the solvent.  The solution of complex intermediate product is then added to water or an aqueous acid such as hydrochloric or acetic acid to liberate the nitro compound, which may be isolated by evaporating the solvent from the solvent layer and distilling the residual nitro compound.  In examples: the interaction of ethyl magnesium bromide or iodide, or ethyl zinc iodide with 1-nitro-2-methylpropene-1 yields 1-nitro-2 : 2-dimethylbutane; ethyl magnesium bromide and 2-nitro-2-butene give 2 - nitro - 3 - methylpentane; ethyl magnesium bromide and 2-nitropropylene give 2-nitropentane; phenyl magnesium bromide and 2-nitro-2-butene give 2-nitro-3-phenylbutane; n-dodecyl magnesium bromide and 2-nitro-2-butene give 2-nitro-3-methylpentadecane; methyl magnesium iodide and tertamyl magnesium chloride give with 1-nitro-2-methyl-propene-1, nitroneopentane and 1-nitro-2 : 2 : 3 : 3 - tetramethylpentane, respectively; n-butyl magnesium bromide with nitroethylene gives 1-nitrohexane, and with 1-nitro-2-furyl-ethylene gives 1-nitro-2-furylhexane; 1-nitro-1-propene with cyclohexyl magnesium bromide yields 1-nitro-2-cyclohexyl propane and with p-bromophenyl magnesium bromide, 1-nitro-2-p-bromophenylpropane; benzyl magnesium chloride and 1-nitrocyclohexene yield 1-nitro-2-benzylcyclohexane; and allyl magnesium bromide with 1-nitro-2-methyl-propene-1 yields 1-nitro-2 : 2-dimethyl-4-pentene. The organometal halides may be prepared in etheral solution by the interaction of the appropriate metal and organic halide.  Other organometal halides specified are methyl zinc iodide, propyl magnesium bromide, isobutyl magnesium bromide, tertiary butyl magnesium bromide, n-amyl magnesium bromide, 2-ethyl hexyl magnesium bromide, cyclopentenyl magnesium bromide, cetyl magnesium bromide, 1-butinyl magnesium bromide, 1-hexinyl magnesium bromide, m-chlorophenyl magnesium bromide, p-anisyl magnesium bromide, a - and b -naphthyl magnesium bromide, 4-methyl-1-naphthyl magnesium bromide, tert.-amyl magnesium chloride, allyl magnesium chloride, 2-methallyl-1 magnesium chloride, p-chlorobenzyl magnesium chloride, and a -naphthyl methyl magnesium chloride.

Title: Low-temperature, high pressure, catalytic conversion of hydrocarbons to hydrogen
IPC: C01B3/38
Filed: 1965-01-12
Abstract: In a process for steam-reforming liquid and/or gaseous hydrocarbons over a nickel catalyst at 550 DEG  to 900 DEG  F. (288 DEG  to 482 DEG  C.) at a pressure of 150 to 1500 p.s.i.g., the surface area of the nickel is initially 20 to 60 m.2 per gram, and the space velocity is controlled so that the hydrocarbon conversion rate is 5 to 40%.  A hydrogen-rich gas mixture is thus produced which is low in CH4, and the catalyst life is prolonged. Space velocities of 20 to 100 (lbs. hydrocarbon per hour per lb. catalyst), corresponding to residence times of 36 to 180 seconds, are mentioned.  The feed may be mainly C5 to C10 paraffins, and unreacted hydrocarbons are condensed out of the product gas.  The catalyst is preferably 40 to 60 weight per cent nickel and 60 to 40 weight per cent alumina or silica, with a promoter metal added. As catalyst activity decreases, the temperature should be increased, and with it, the pressure, to decrease carbon formation.  A specific comparative example is described.

Title: Compensated phototube amplifier
IPC: H04B15/02
Filed: 1952-01-18
Abstract: 739,707. Photo-electric facsimile reproduction system. STANDARD TELEPHONES & CABLES, Ltd. Jan. 18, 1952 [Feb. 28, 1951], No. 1499/52. Class 40 (3). In a facsimile reproduction system in which a lamp illuminates a portion of a copy sheet and a photo-tube receives light reflected from the sheet, variations in the supply voltage are arranged to vary the bias voltage of a tube fed by the cell so as to compensate for changes in source brightness. As shown photo-cell 12 receives light from an A.C. fed source EL reflected from the copy sheet C. A chopper disc D provides high-frequency interruptions of light falling on the sheet. The light source is fed from a secondary winding of a mains transformer 29 which also supplies a high voltage which is rectified, smoothed at 26 and then supplied to series potentiometers 23 and 25 and resistor 24. A voltage tapped from potentiometer 23 is fed through a voltage-stabilizing circuit comprising resistors 22, 16, 17, 18 and neon tubes 20, 21 to the grid of a tube 14 which amplifies the photo-cell output. Thus the grid of tube 14 is maintained at a constant potential. The cathode of the valve, however, is fed from potentiometer 25 so that its potential rises and falls with the supply voltage thus automatically compensating for changes of brightness of the source due to voltage fluctuations. The effect of the A.C. fluctuations of the lamp is eliminated by an arrangement described in divisional Specification 739,730.
