Abstract: 1,176,664. Oxidation of unsaturated organic compounds. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 June, 1967 [6 July, 1966], No. 30287/66. Heading C2C. Unsaturated organic compounds are oxidized in the presence of a salt or co-ordination compound of palladium and an ionizable cyanate, by contacting with a nucleophilic compound HA, such as water, aliphatic and aromatic alcohols, aliphatic or aromatic mono- or dicarboxylic acids. Olefinic compounds, e.g. aliphatic α-olefines, cranked wax (C 14 ) or aryl substituted, e.g. styrene, non-terminal olefines, diolefines, olefinic acids, alcohols and esters and aromatic compounds e.g. benzene and toluene may be used. α-olefines with carboxylic acid yield unsaturated esters, with water yield aldehydes or ketones, and with an alcohol yield ethers and acetals. A palladious salt, e.g. chloride, bromide a carboxylate is preferred, and lithium chloropalladite and dichlorobis- (benzonitrile) palladium II are mentioned. The salt may be formed in situ. The cyanate includes isocyanate, and alkali metal or alkaline earth metal cyanates or cyanic acid may be used. Conventional organic or inorganic redox systems may be used in the presence of molecular oxygen for regeneration. Examples describe the oxidation of propylene to allyl acetate, acetone, isopropenyl acetate and acrolein and ethylene to vinyl acetate and acetaldehyde.

Title: Polyvinyl acetate powder and method of making the same
IPC: C08J3/16
Filed: 1958-09-23
Abstract: A dry polyvinyl acetate powder, which can be reconstituted upon the addition of water to form an emulsion having substantially the properties of the original aqueous emulsion from which it is obtained, is prepared by spray-drying the aqueous emulsion and, before the polyvinyl acetate is completely dried, adding thereto an inert material, the drying of the polyvinyl acetate being completed in the presence of the inert material.  Inert materials are exemplified by pigments and fillers such as clay, talc, calcium carbonate, silica, diatomaceous earth and titanium dioxide.  Not less than 5% of inert material, based on the weight of the dried polyvinyl acetate powder, is employed.  Preferred polyvinyl acetate emulsions are those in which the polyvinyl acetate particles have an average grain size of 2-8 microns and provide a solids content of 15-35%. Polyvinyl alcohol of low viscosity may be added as a stabilizer to the emulsion before spray-drying, the alcohol content being at least 10% by weight of the total solids present in the emulsion.  A plasticizer may be incorporated into the dry polyvinyl acetate powder by mixing the plasticizer with an inert carrier and adding the mix to the polyvinyl acetate after the latter has been spray-dried or before the latter is completely dried by the spray-drying process.  In either case inert material is also employed.  Plasticizers exemplified are dipropylene glycol dibenzoate, dibutyl phthalate, and the mono-ethyl ether of diethylene glycol acetate.  Inert carriers are preferred which have high absorptive capacity for the plasticizer, e.g. calcium silicate.  Spray-drying is effected with maximum air inlet and outlet temperatures of 300 DEG F. and 130 DEG F.ALSO:<PICT:0866038/III/1> A dry polyvinyl acetate powder, which can be reconstituted upon the addition of water to form an emulsion having substantially the properties of the original aqueous emulsion from which it is obtained, is prepared by spray-drying the aqueous emulsion and, before the polyvinyl acetate is completely dried, adding thereto an inert material, the drying of the polyvinyl acetate being completed in the presence of the inert material.  In Fig. 1 emulsion to be dried is fed into an atomizing device and hot air at a temperature not exceeding 300 DEG F. forces the spray into a vortex.

Abstract: 519,397. Purifying oils; regenerating used alkali. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Oct. 21, 1938. No. 30542. Convention date, Nov. 15, 1937. Drawings to Specification. [Class 91] Hydrocarbon oils and similar liquids are freed from mercaptans by aqueous caustic alkali and a solution promoter for mercaptans. The used alkaline solution is regenerated by diluting with water and passing in steam, maybe under pressure. A limited proportion of air may be mixed with the steam, a catalyst promoting oxidation of mercaptides to disulphides then preferably being present, e.g., mixed with the solution. The steam may be obtained by concentration of the stripped alkali solution, and the predilution of the used alkali may be effected by water of condensation from the steaming. Solution promoters specified are:-amino- or hydroxy-alkylamines ; polyhydric alcohols or derivatives thereof, e.g., propylene glycol, butylene glycol, alkyl glycerines, alkyl glycerine ethers, di- and tri-ethylene glycol, mono-, di-, and triethylene glycol alkyl ethers, diamino-alcohols; alkali metal salts of fatty acids containing 2-6 C atoms e.g., potassium isobutyrate, or of amino- or hydroxy-fatty acids containing 3-7 C atoms, e.g., potassium hydroxy-n-butyrate, or of phenyl-acetic acid. Suitable alkalies are alkali metal hydroxides or carbonates, ammonia, and quaternary ammonium bases. The preferred catalysts are the oxides and sulphides of vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, cadmium, and lead. A little alkali sulphide may be dissolved in the caustic alkali to prevent the formation of soluble compounds of copper or other catalyst metals. In an example, Californian gasoline is extracted in two stages with 20 per cent. by volume of 6N potassium hydrate containing 400 gm. per litre of potassium iso-butyrate. The spent caustic potash is then regenerated by diluting, and steaming with 1 liquid vol. of steam per vol. of solution using a 6 plate fractionating column. Specifications 494,450 and 494,451 are referred to.

Title: Improvements in or relating to apparatus for the development of photographic films
IPC: G03D3/10
Filed: 1960-09-08
Abstract: 909,166. Photographic developing apparatus. BEUMERS, M. Sept. 8, 1960, No. 30924/60. Class 98 (2). A developing apparatus has successive treatment tanks 2a, 2b, 2c, the exposed films being carried in frames such as 3. Each frame is carried by a strap 8 fitting round a lead screw 4 running above the sequence of tanks, and having a pin 9 engaging in the thread of the screw. As the lead screw is turned by handle 4x, the film carrier frame is caused to traverse the tank from side to side. The portions 4a, 4b, 4c of the lead screw corresponding to the different tanks are of differing pitch, according to the varying treatment times required for each tank. As the carrier frame reaches the end of each tank, it rides up over the curved shoulder of a guide plate 5, and so swings upwards about the axis of the lead screw. The carrier frame is thus lifted clear of the tank, and the dividing wall, and is guided down over the other shoulder of the guide plate into the next tank. The sections 4ab, 4ac of the lead screw between the tanks have a substantially larger pitch, so that the frame carrier 3 moves up and down rapidly in clearing the wall between one tank and the next.
