Patent GB-480320-A (GB)
Title: Improvements in the manufacture of 2-chlor-1.3 butadiene
IPC: C07C17/26
Filed: 1936-08-17
Abstract: 2-Chlorbutadiene-1.3 is prepared by introducing a mixture of vinyl chloride and acetylene into a heated solution containing cupric chloride, the copper salt of divinylacetylene and hydrogen chloride formed intermediately reacting to give 2-chlorbutadiene-1.3 and regenerate cupric chloride and acetylene. In an example, the gases are passed into a solution of cupric and ammonium chlorides at 88 DEG C.  The chlorbutadiene may be polymerized by heat in the presence of acetic or hydrochloric acid.  U.S.A. Specification 1,950,435 is referred to.  The Specification as open to inspection under Sect. 91 states that the regenerated acetylene can be polymerized to divinyl acetylene by contact with the catalyst at 90 DEG  C.  This subject-matter does not appear in the Specification as accepted.

Filed: 1972-05-15
Abstract: 1350726 Purification of carboxylic acids MONSANTO CO 15 May 1972 [10 Nov 1971] 22643/72 Heading C2C Monocarboxylic acids (preferably 2-10 C) are purified from water and alkyl halide and/or hydrogen halide contaminants by introducing a product stream into the upper half of a distillation zone, removing an overhead fraction containing water and alkyl halide, removing a stream from the middle portion of the distillation zone but below the introduction point, and removing a purified stream from the lower part of the zone. In a modification the impure acid may be pre-distilled in a zone from which the bottom portion containing hydrogen halide is removed and the overhead stream is passed to the upper half of the distillation zone. The acid to be purified is preferably that prepared by the reaction of an alcohol or olefine with carbon monoxide in the presence of a catalyst system containing a Group VIII noble metal component and a halogen component, usually bromine or iodine. Examples describe the purification of acetic acid containing hydrogen iodide and methyl iodide.

Title: Method of carrying out exothermic processes in fluidized beds
IPC: F23C10/10
Filed: 1977-05-31
Abstract: 1534645 Combustion or calcination in fluidized beds METALLGESELLSCHAFT AG 31 May 1977 [31 May 1976] 22989/77 Heading F4B An exothermic reaction, i.e. combustion or calcination of sulphur bearing ores, is carried out in a fluidized bed reactor under substantially stoichiometric conditions, the combustion air being fed to the bed in at least two streams entering the bed at different loads, solids taken from the bed are cooled in a second fluidized bed, air from the cooling bed being fed to the reactor as secondary air, and at least some of the solids are recycled to the bed to regulate the temperature. Part of the combustion air may be used as fluidizing gas, and the ratio of secondary air to fluidizing air is such that the fluidized bed substantially fills the reactor 1, solids removed from the exhaust gases by a cyclone 9 being returned directly to the reactor 1. Gases from the cyclone 9 pass through a waste heat boiler 2, electrostatic precipitator 3 and air preheater 4 to atmosphere, and solids taken from the bed in the reactor are fed at 11 to a multiple fluidized bed cooler 5, the cooled solids being fed to the bed at 15 or taken off at 16. The air heated in the cooler 5 is returned to the reactor at 8 together with air from the preheater 4 which also supplies fluidizing air at 7. Material is fed to the reactor through a liner 6 below the secondary air inlet by part of the preheated air. Steam may be produced in the cooler 5. Some of the solids withdrawn from the cooler may be used to cool the exhaust gases from the cyclone 9 before they are fed to the electrostatic precipitator. The Specification gives desirable values for the density of the fluidized bed above the secondary air inlet, the ratios of the volumes of fluidized gas to secondary gas supplied, and the position of the secondary air inlet in the reactor.

Title: Improvements in pipe couplings of the swivel type
IPC: F16L27/08
Filed: 1921-09-02
Abstract: 189,852. Haddan, A. J. H., (Titeflex Metal Hose Corporation). Sept. 2, 1921. Hinge and swivelling joints with packing operated by fluid pressure.-In a swivel coupling for pipes in which a resilient packing element between the two coupling members is operated by fluid pressure, the packing element, either in the form of a helically corrugated tube or of a diaphragm, is secured to one member and bears against a seating of the other member. In Fig. 1, a helically corrugated tube 14, which may be constructed as described in Specification 101,418, is soldered at one end to a flange 13 on a plug 2 screwing into one end of a sleeve 1, the other end of which has a flange 3 against which the shoulder 8 of the second member 7 bears to form a swivel bearing. The other end of the tube 14 is soldered to a seat member 15 which is normally pressed against the shoulder 9 on the member 7, a gasket 16 being preferably interposed, by the resiliency of the tube 14, the joint being made tighter by the fluid pressure in the pipes. In order to prevent tilting of the coupling members with respect to each other, the projection 10 on the member 7 enters the recess 11 in the plug 2 and is also limited in its longitudinal movement by the flange 6 on the plug 2. In. a modification, Fig. 3, the packing element is in the form of a diaphragm 25, with a central hole 26, clamped between a plug 19 and sleeve 18 and having a seat member 27 which is normally pressed by the spring of the diaphragm 25 against the end of the pipe 20, the flange 21 on which turns upon the flange 22 on the sleeve 18 in the swivelling action. A gasket 28 is preferably interposed between the seat member 27 and pipe 20. Fluid pressure in the 'pipes increases the pressure of the diaphragm seat member 27 against the end of the pipe 20.

Filed: 1926-09-24
Abstract: 259,553. Sharples Specialty Co., (Assignees of Jones, L. D.). Oct. 7, 1925, [Convention date]. Mineral oils, purifying; paraffin wax, extracting.-Petroleum, after the gas, naphtha, and burning oils have been distilled off, is treated for the removal of wax while still containing impurities removable by clay treatment. A distillate of this topped petroleum may be similarly treated. The topped petroleum may be blended with other products to ensure a sufficiency of such impurities. To separate hard asphalt or other impurities interfering with the separation of the wax, the oil may be treated with acid, e.g. 66‹ BÚ. sulphuric acid, or be distilled, the distillate being similarly acid treated if necessay to remove any such impurities carried over. In an example, crude petroleum is heated to distil off the gas, naphtha, and burning oils, cooled to about 50‹ C., diluted with 62 per cent of naphtha, heated to about 38‹ C. to ensure solution of all wax, gradually chilled to -23‹ C., and centrifuged. The naphtha is distilled off. The wax-free oil may be fractioned, as by steam distillation, to produce lubricants of various grades, the cylinder stock being refined by clay; or the oil from the centrifuge, before or after removal of the naphtha diluent, may be refined by clay, and the product fractioned. The precipitated wax may be removed from the chilled liquid by addition of wood pulp or paper stock, or by other known method in place of centrifuging.
