Title: Process for the preparation of aromatic nitro-carboxylic acids
Inventor: COTTERILL COLIN BERTIE
IPC: C07C205/57
Filed: 1956-11-16
Abstract: The invention comprises a process for the production of nitro-carboxylic acids of an aromatic character by oxidizing in the liquid phase a hydrocarbon of aromatic character, substituted by at least one alkyl group, or closely related oxygenated derivative of an alkyl group, and by at least one nitro group, by means of molecular oxygen or ozone in the presence of a catalyst comprising the halide of a metal of variable valence.  Suitable oxygenated derivatives of an alkyl group, which may be substituted in the nucleus of the starting material are carboxylic, aldehydo, keto, alcohol, ester, or hydroperoxide groups.  The starting material may contain up to three alkyl groups or residues thereof.  Preferably the catalyst comprises the mixed bromides of cobalt and manganese, although mixtures of cobalt and lead, or lead and manganese bromides may be used. Suitable proportions of the catalysts are from 1 to 0.0005 gramme atom of total metal per gramme mol. of starting material.  The preferable ratio of manganese to cobalt is about 2 : 1, and suitable proportions of manganese dibromide (MnBr2.4H2O) and of cobaltous bromide (CoBr2.6H2O) are respectively 0.1 to 200 per cent, and 0.05 to 100 per cent by weight of the starting compound assuming a molecular weight of 100.  The metal halides are preferably introduced into the reaction mixture as such, but may be produced in situ by using salts of the metals which are soluble in the reaction mixture, e.g. the acetates or naphthenates and introducing halogen, e.g. bromine or hydrobromic acid or an alkali metal bromide such as sodium.  Bromine may also be introduced in the oxygen stream and the catalytic metal may be introduced as, e.g. Raney metal, carbonyl or oxide.  Chlorides and iodides may also be used.  During the process of the invention any lost halogen may be replaced by hydrogen halide, the halogen itself or a halogeno derivative of the aromatic starting material.  A solvent, e.g. C2-C6 aliphatic carboxylic acids, aromatic hydrocarbons, halogen derivatives of benzene, e.g. o-dichlorobenzene, aromatic carboxylic acids, and water may be present in the reaction mixture.  The molecular oxygen may be fed in as air or introduced in situ, e.g. by decomposition of a compound such as hydrogen peroxide. The process may be carried out batchwise at, temperatures of from ambient up to 300 DEG  C. at up to 200 ats. gauge, or continuously. Reactions specified are the preparation of 3-nitropyridine-5-carboxylic acid from 3-nitro-5-methyl pyridine, p-nitrobenzoic acid from p-nitrotoluene, p-nitroethylbenzene, and p-nitrocumene, m- and o-nitrobenzoic acid from m- and o-nitrotoluene respectively; 3,5-dinitrobenzoic acid from 3,5-dinitrotoluene; 4-nitrophthalic acid or its anhydride from 4-nitro ortho xylene.

W. ; Rocky Point, Long Island, New York, U.S.A.) Dec. 18, 1933, No. 35621. Convention date, Dec. 17, 1932. [Class 40 (v).] A magnetron oscillator is modulated in frequency by varying the anode voltage, or the magnetic field strength, or both, and amplitude modulation is eliminated either by a limiting- device or by a suitable relation between the modulating potentials applied respectively to the anode and to the field coil. As shown in Fig. 3, signals are applied through a transformer 12, potentiometer 22, and amplifier 14, thus varying the voltage across a resistance or coil 16 which is in the anode circuit of the magnetron 4. The steady anode voltage and the field created by the coil 8 are so adjusted that variations of anode voltage or of the coil current do not affect the amplitude but only the frequency of oscillation. The modulated wave may be fed to an aerial 30 through amplifiers, frequency multipliers, and limiters. The modulating signal may be applied to the main field coil 8 or to an auxiliary field coil either directly or after amplification. As shown in Fig. 8, a split-anode magnetron is employed, and the signal is applied jointly to the field coil 50 through a transformer 58 and to the anode supply lead 54 through a transformer 48.
