Title: The manufacture of products containing nitrogen
IPC: C07C209/08
Filed: 1929-09-11
Abstract: 339,962. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Sept. 11, 1929. Nitrogenous derivatives of paraffins are obtained by treating halogenated paraffins containing more than 8 carbon atoms with aqueous or alcoholic ammonia or an agent yielding ammonia, e.g., ammonium carbonate or urea.. Pressure, and copper or copper compounds' which act as catalysts may be used. The halogen atoms are in part replaced by amino groups and in part split off with formation of double bonds, while others may remain in the molecule. When alcoholic solutions are employed the alcohol may react with the production of ether groups. Secondary and tertiary amines and quaternary ammonium compounds may also be obtained as secondary reactions. In examples, the following halogenated paraffins are heated in an autoclave with a solution of ammonia in ethanol or methanol; a dichlorinated hard paraffin produced by introducing chlorine into 367 parts of hard paraffin until an increase of 69 parts by weight is obtained, a di- or tetra-chlorinated easily fusible paraffin (mean molecular weight 255) prepared from the parent oil and chlorine, a hexa-chlorinated hard paraffin (mean molecular weight 367) and an octa-chlorinated hard paraffin (mean molecular weight 325) both prepared by direct chlorination, and a chlorinated transformer oil (specific gravity 0.88) prepared by treating 100 parts of the oil with chlorine until 64 parts by weight of chlorine have been absorbed. Copper sulphate is used as a catalyst in treating the hexachlorinated hard paraffin with alcoholic ammonia, and the use of aqueous ammonia or ammonium carbonate for treating the hexachlorinated hard paraffin is described.

Title: Insect repellent compositions and their use
Filed: 1949-11-08
Abstract: An insect-repellent composition comprises one or more alkane diols possessing vicinal hydroxy groups and 7 to 12 carbon atoms in the molecule and, in addition, a known non-solvent insect repellent or insecticide.  In place of, or in addition to, the alkane diol there may be used a carboxylic acid ester of the alkane diol, or a halogen substituted derivative of the diol or ester, in which the substituent halogen atom or atoms is or are directly linked to a carbon atom or atoms.  Specified diols are 1,2-octane diol, 2,3-octane diol, 1,2-heptane diol, 1,2-undecane diol, 1,2-dodecane diol and their acetates, formates, benzoates, cinnamates and phthalates.  Typical known insect-repellents are dimethyl phthalate, a mixture of dimethylphthalate, 2-ethyl hexandiol-1,3 and n-butyl mesityl oxide oxalate, oil of citronella, 2-ethyl hexandiol-1,3 per se, and cyclohexyl cyclohexanol.  Specified insecticides are hexachlorocyclohexane, D.D.T., and those of Specification 582,205.  A fungicide such as salicylanilide may be present.  The compositions may be in the form of solutions in organic solvents or soluble oils, aqueous emulsions, pastes, ointments, solid blocks or dusting powders mixed with e.g. talc and fuller's earth.  It is preferred that the diol or ester thereof forms 10 to 50 per cent by weight of the insect-repellent present in the composition.  An example is given of an insect-repellent cream consisting of stearic acid, potassium carbonate, secondary alkyl sulphates, glycerol, water and a 1 : 1 mixture of 1,2-octane diol and dimethyl phthalate. The diols may be incorporated in larvicidal oils e.g. diesel fuel oil.  The diols may be prepared by the method of Specification 634,118, [Group IV (b)].

Title: Improvements in or relating to the production of oxygen-containing organic compoundsfrom carbon monoxide, hydrogen and olefins
IPC: C07C27/22
Filed: 1950-11-23
Abstract: Oxygen-containing organic compounds are produced by (a) continuously contacting a solid cobalt compound or cobalt metal with carbon monoxide, recovered subsequently in the process, in a catalyst-generating zone at a temperature in the range 30-250 DEG C. and at a partial pressure of carbon monoxide of 20-300 atm., in the presence or absence of a solvent, to produce cobalt carbonyl; (b) passing the cobalt carbonyl to an OXO synthesis reaction zone, operated in continuous manner without the introduction of solid cobalt compounds and in which an olefin is contacted with carbon monoxide and hydrogen at an elevated temperature and at a pressure of at least 50 atm. and (c) separating carbon monoxide from the product stream by chemical and/or physical means and using this carbon monoxide for the generation of cobalt carbonyl. The preferred pressure range in the OXO reaction zone is 30-250 atm.  Hydrogen may be separated with carbon monoxide from the residual olefin and reaction products and may be used for the hydrogenation of product aldehydes to alcohols.  The carbon monoxide may be separated from hydrogen by scrubbing the mixture with a solution of copper ethanolamine nitrate or copper ammonium formate.  Preferably the ratio of carbon monoxide to hydrogen fed to the OXO synthesis zone is in the range 0.9 : 1 to 1.1 : 1.  The preferred conditions in the catalyst generating zone are a temperature range of 50 to 200 DEG C. and a pressure range of 100-300 atmospheres.  The catalyst and olefine feed rates to the reaction zones are preferably adjusted to maintain the weight of cobalt between 0.01 and 5 per cent. of the weight of olefine feed.  The cobalt in the effluent from the OXO reaction zone may be recovered by conventional methods.  In the example pelleted black oxide of cobalt is reduced at 300-370 DEG C. at atmospheric pressure; a continuous stream of carbon monoxide recovered from the products of the OXO synthesis reaction is passed over it and the effluent gas containing cobalt carbonyl is used as catalyst in the production of butyraldehyde by the reaction of carbon monoxide and hydrogen or propylene; the reactants and catalyst are passed upwards through the reactor at 3,000 lbs./sq. in. and 130 DEG -160 DEG C., the products cooled and the gas phase separated for recovery of carbon monoxide.  The carbonyls present in the liquid phase are decomposed and isobutyraldehyde and normal butyraldehyde are obtained by distillation of the remaining liquid.  Specifications 482,654, [Group III], 702,191, 702,192, 702,195, 702,196, 702,197, 702,201, 702,203 and 702,204 are referred to.
