Title: Olefin oxidation
IPC: C07C67/055
Filed: 1964-06-11
Abstract: In the liquid phase oxidation of olefins with a substantially anhydrous organic solution containing a platinum metal and halogen in presence of oxygen at 30-300 DEG  C., deposits of the metal upon the apparatus surface are prevented by incorporating in said solution between 1 and 20 weight per cent of a finely divided inert solid. The solid, impregnated with the precipitated metal during the oxidation or distillation, is recycled with the catalyst solution. Suitable solids are silicas, preferably silica gel, silicon carbide, carbons, and titania, preferably having a specific surface area of 2-1000 m2/g, and generally of 3-400 mesh (U.S. Standard).  The metal may be Pt, Ir, Os, Rh, Ru or, preferably, Pd, usually in amounts of 0.001-5 weight per cent of the solution. It may be added as metal, soluble salt or oxide or chelate.  The halogen may be added as Cl or Br; hydrogen, alkali, ammonium or platinum metal halide; or organic halide or phosgene. The water content of the reaction medium should be less than 20 weight per cent and reaction water formed is removed by distilling. Aliphatic alcohols of C1- 25 are preferred solvents for oxidation of olefins to acetals, a strong mineral acid in amount of 0.1-5% being added. Carboxylic acids are used in preparing unsaturated esters.  Soluble carboxylates of alkalis, alkaline earths, and noble metals of Group VIII, or redox metal salts, e.g. halides, may also be present.  Additional solvents include formamide, dimethyl formamide, hydrocarbons, and chlorhydrocarbons.  Other oxidizing agents may also be used such as nitrogen oxides, nitrates or nitrites.  Vanadium compounds may be added to catalyse oxidation of oxalic acid formed as a by-product.

Title: Improvements in the production of anthraquinone derivatives
IPC: C09B1/473
Filed: 1930-08-14
Abstract: Aminohalogenanthraquinones.--A dihalogenated anthraquinone in which both halogens occupy a -positions is converted to a monohalogenated - monoarylsulphonamidoanthra - quinone by condensing with at least one molecular proportion and substantially less than two molecular proportions of an aryl-sulphonamide in the presence of an organic liquid medium, for example o-dichlorbenzene, in which the desired product is substantially insoluble.  By a subsequent hydrolysis, for example by means of sulphuric acid, a .a -monaminomonohalogenanthraquinones are obtained.  The condensation may be effected in the presence of an acid-absorber and a copper catalyst, such as pure potassium carbonate and a dry mixture of copper acetate and cuprous chloride, and preferably at or near the boiling-point of the mixture, viz., about 175-180 DEG  C., and high yields are smoothly obtained.  The hydrolysed product is purified by fractional precipitation from sulphuric acid.  In examples, (1) 1 : 5-dichloranthraquinone is condensed with p- and o-toluenesulphonamide to give 1-chloro-5-p- and o-toluenesulphonamidoanthraquinones respectively; these products are hydrolysed by heating to 100 DEG with sulphuric acid, the resulting product dyeing cellulose acetate a deep yellow shade: (2) 1 : 4-dichloranthraquinone is similarly condensed with p-toluenesulphonamide and the resulting 1-chlor-4-p-toluenesulphonamidoanthraquinone similarly hydrolysed.

Title: Method and machine for forming fused seams in sheet thermoplastic material
IPC: B65B51/14
Filed: 1955-08-29
Abstract: 775,061. Seaming. GRACE & CO., W. R. Aug. 29, 1955 [Aug. 30, 1954], No. 24735/55. Class 42 (1). A fused seam is formed between two sheets of thermoplastic material by placing the sheets between two relatively movable sealing jaws 13, 44, closing the jaws so that they firmly contact the sheets and then arresting the closing movement, heating the seam area of the sheets until the material becomes plastic and thereafter closing the jaws further so as to apply full sealing pressure to the sheets. As shown, Fig. 1, the jaws 13, 44 are conductively heated by elements 16, 47 respectively and are covered with an antisticking material such as " Teflon " (Registered Trade Mark); radio-frequency electrodes may, however, be substituted. The lower jaw 13 is provided with a heat-resistant compressible pad 14 and is mounted on a frame plate 12, with an interposed layer 17 of insulating material. An air cylinder 18, suspended from plate 12, acts through a bar 24 and rods 33, 34 to raise and lower a top plate 43 carrying the upper jaw 44. The closing movement of the jaws is limited by engagement of adjustable stop screws 62, 63 with stops 58 projecting from the pistons 57, Fig. 2, of air cylinders 49, 51. A control system provides the following operational sequence : (a) low pressure air is applied to the top of cylinder 18 to lower jaw 44 until stops 62, 63 meet stops 58 which are maintained in their raised positions by high pressure air supply; in this position, pad 14 is slightly compressed ; (b) after a predetermined short heating. period, cylinders 49, 51 are exhausted, permitting stops 58 to fall to their lower positions, and high pressure air is applied to the top of cylinder 18, so that jaw 44 descends a further short distance under full sealing pressure; (c) after a short dwell of predetermined duration jaw 44 is raised from the seam by low pressure air applied to the bottom of cylinder 18. The sealing surface of jaw 44 is formed with a radius or bevel to provide a wedging action which forces plastic material inwardly of the seam to form a convex portion 104, Fig. 3; the sheets 101, 102 shown are of a vinylidene copolymer oriented film, the increased thickness at 103 resulting from shrinkage due to disorientation of the film by the applied heat.
