A hydroformylation process is performed by contacting an olefinic compound with a mixture of CO and H 2  in the presence of a catalyst obtained by reducing a Co compound, in the presence of CO and in the absence of air, by means of a reducing agent containing at least one Me-X bond, where X is H or a hydrocarbon radical and Me is a metal. The reduction is preferably carried out in a hydrocarbon solvent using a metal hydride or an organometallic/alu. minium compound at 0-300‹ C. Advantageously 10<SP>-4</SP> to 10<SP>-1</SP> mole of catalyst per litre of reaction mixture is employed and the pressures of CO and H 2  are each between 0.1 and 100 bars. In the examples the catalyst is prepared by reducing cobalt acetylacetonate under a CO atmosphere with (1) diethylethoxyaluminium, (2) A1H(OC 2 H 5 ) 2 , and (3) A1H 3  and is used in the hydroformylation of cyclohexene to hexahydrobenzaldehyde.

Filed: 1939-11-13
Abstract: 536,428. Alcohols. DREYFUS, H. Nov. 13, 1939. No. 29959. [Class 2 (iii)] In the production of aliphatic hydroxy compounds by the hydrolysis of the corresponding halogen compounds is the absence of acid-binding agents, the hydrolysis is effected with sufficient water and at such a temperature below the boiling-point of the hydroxy compound formed, that the hydrohalide acid is continuously removed as an azeotropic mixture with water. The invention is described with reference to the produc-- tion of glycerol, but is also applicable to the production of other aliphatic hydroxy compounds such as a monochlordihydroxy propane from 1-2-3-trichlor propane and a butylene glycol from the corresponding chlorhydrin or dichlor compound. In an example a distillation column is charged with an aqueous glycerol at its boiling-point (150‹C.) and a 10 per cent. aqueous glycerol monochlorhydrin is introduced at an intermediate. point in the column so that aqueous hydrochloric acid distils off and crude glycerol is removed at the base and. is purified by fractionation at 10-15 mm. and then by treatment with caustic soda and redistillation.

Title: An improved process for the vulcanisation of rubber goods
IPC: C08J3/24
Filed: 1935-10-30
Abstract: Rubber articles containing either a vulcanizing agent (e.g sulphur) or an accelerator are vulcanized by immersion in a saturated organic solution of either an accelerator or a vulcanizing agent respectively, the solvent being such that the accelerator or vulcanizing agent is only slightly soluble therein and saturation being ensured by the presence in the solution of an undissolved sediment of accelerator or vulcanizing agent.  In examples: (1) rubber containing sulphur is dipped into a saturated solution of piperidine salt of pentamethylene dithiocarbamic acid and cyclohexylethylamine salt of cyclohexylethyldithiocarbamic acid in benzine; and (2) rubber containing the accelerators is dipped into a saturated solution of sulphur in benzene.  Instead of benzine, alcohol or ether can be used.

Title: Process of preparing a gellable colloidal cellulose sulfate and product
Inventor: SCHWEIGER RICHARD G
IPC: C08B5/14
Filed: 1965-07-15
Abstract: A gellable cellulose sulphate ester having a D.S. of 1-3 is made by mixing cellulose, sulphur trioxide and a lower N-dialkylamide in which the alkyl groups contain 1 to 4 carbon atoms. The sulphating agent may be a complex of sulphur trioxide with an N-dialkyl amide, at least 1 mole of the latter being combined with 1 mole of sulphur trioxide.  The cellulose, to which the complex is added, is preferably in admixture with a N-dialkyl amide diluent, which may be the same compound as used for the complex formation.  Esterification is suitably carried out at 0-25 DEG  C. for 2-8 hours using 1-8 parts of a 1:1 SO3-N-dialkyl amide complex per 1 part of cellulose.  The product may be neutralized by alkali and precipitated by alcohol or acetone.  Specified N-dialkyl amides are dimethyl formamide, diethyl formamide, dimethyl acetamide, diethyl acetamide and dimethyl propionamide.  The esters may be obtained in free acid form or as salts with metallic or organic cations.  The esters form thermo-reversible aqueous gels in presence of potassium or ammonium ions.ALSO:An edible milk gel is made by adding 1 cup of hot milk to a dry mixture of potassium cellulose sulphate (3.0g); sodium chloride (0.1g); vanillin (0.1g) and sugar (35.0g).

[Class 40 (v).] In a short-wave valve oscillator, the normal oscillatory circuit comprising the anode-grid capacity C a n d a short-wave coil L1, Fig. 1, is shunted by a second circuit L2 the wave-length of which is greater than, but less than twice, that of the normal circuit, the object being to increase the energystoring capacity of the oscillator without increasing the voltage swing on the valve electrodes, or substantially increasing the wave-length of the oscillator. As shown in Fig. 5, a push-pull pair of valves VI, V2 have their plates connected by a shortwave, coil L1, and their grids by a similar coil L1<SP>1>. The two coils and the plate to grid capacities constitute the frequency-determining circuit. The added circuit comprises two pairs of Lecher wires L2, L2<1> with adjustable bridgepieces B, B1 to the centre of which the plate and grid voltage sources are connected. Best results are obtained when the bar B is removed three-eighths of a wave-length from the plates. The bar B1 may serve as a fine adjustment for wave-length. In the single-valve oscillator, Fig. 6, a large condenser C1 and an inductance L1 are in the frequency-determining main circuit, whilst the added circuit comprises Lecher wires L2 (or a coil whose natural wavelength is three-halves the working wave-length), and a large condenser C2.
