Title: Process for the production of water-soluble high molecular ª‡-substituted quaternary benzylammonium halides and the resulting products
Filed: 1942-10-26
Abstract: Quaternary ammonium halides are obtained by heating tertiary amines with aralkyl halides having the formula C6H5CH(halogen)Alkyl which must contain at least one aliphatic or cycloaliphatic residue having at least 8 carbon atoms.  The benzene ring may be substituted.  In an example 1-(a -chlordodecyl)-4-methylbenzene is heated with trimethylamine.  Triethylamine, tributylamine, pyridine and dimethylbenzylamine are mentioned and also a -halogenethyl, propyl and butylbenzene derivatives containing nuclear high molecular substituents. Aralkylhalides having the above formula are prepared from arylalkylketones by reducing to the secondary alcohols and replacing the hydroxy group by halogen.  Thus 1-(a -chlordodecyl)-4-methylbenzene or the corresponding bromine compound is prepared from 4-methyllaurophenone by heating in alcohol with aluminium grit activated with mercurouschloride and reacting the resulting alcohol with phosphorus trichloride or tribromide.  Ketones obtained from benzene and lauric acid, toluene or xylene and palm nut fatty acid, anisol or phenetol and naphthenic acid and dodecylbenzene and acetic acid are mentioned as starting materials.

Title: Glass fabric based catalysts
IPC: B01J37/02
Filed: 1959-05-05
Abstract: A catalytic composition comprises a glass fabric base coated with a refractory material and having platinum, palladium or cobalt or an oxide thereof deposited thereon.  The glass fabric base may be woven, knitted or crocheted and may be a quartz fabric; it may be reinforced with fine metal wires.  The refractory material applied to the glass fabric may be a ceramic slip or alumina and may be applied by dipping the glass fabric in a slurry of the refractory material and drying and calcining the product.  If alumina is used as the refractory material, the alumina slurry is preferably fluidized by addition of a nitrate of chromium, yttrium or samarium.  In preparing the catalysts, the refractory-coated glass-fibre fabric is treated with a solution of a soluble compound of the catalytic metal, e.g. chloroplatinic acid, palladium chloride or cobalt nitrate, and the product is dried and heated to decompose the catalytic metal compound.  The decomposition of a platinum or palladium compound may be facilitated by including a reducing organic compound, e.g. sugar, in the original solution.  The catalysts are particularly useful for insertion in the exhaust lines of automobile engines, to decompose unsaturated hydrocarbons, nitrogen oxides and (or) carbon monoxide.

Abstract: 992,788. Centrifugal compressors. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 16, 1964 [April 16, 1963], No. 15833/64. Heading F1C. A centrifugal compressor comprises at least two stages each formed by narrowing rotor passages surrounded by a ring of stationary guide vanes, the rotor also including a diffuser part, and the ratio of the energy-converting effect of the diffuser to the energy-increasing effect of the rotor is greater in the higher pressure stage then in the lower pressure stage. This reduces the tendency towards irregularities of flow caused by the formation of boundary layers having a thickness which is large compared with the cross-section of the fluid flow. Since this tendency is less in lower pressure stages, the first stage rotor 29 of the compressor shown is not extended by a diffuser part. The second and third stage rotors 30, 31 have unbladed diffuser parts 19, 28 adjacent the bladed rotor channels 17, 18. The ratio of the energy-converting effect of the diffuser part to the energy-increasing effect of the rotor is arranged to be greater for the rotor 31 than for the rotor 30; for this purpose the radial dimension 21 is made greater than the radial dimension 20. Also, the angle 23 of divergence is greater than the corresponding angle 22. The diffuser inlet width 37 is reduced, but the axial width of the diffuser exit may be greater for the third stage. Preferably, however, this latter dimension is kept constant to allow the guide rings 32, 33, 34 to be of equal width. Intercoolers may be provided.
