Patent GB-760099-A (GB)
Title: Production of pyridines
IPC: C07D213/09
Filed: 1954-11-11
Abstract: Pyridines are produced by a method comprising reacting a 1,1,3,5,5-penta-alkoxypentane with ammonia at elevated temperature. The ammonia may be used, e.g. as anhydrous ammonia, an aqueous solution or an ammonium salt such as the chloride or sulphate.  It is desirable to supply more than one mol. of ammonia for every mol. of penta-alkoxypentane and to carry out the reaction at temperatures between 80 DEG  and 285 DEG  C.  It is preferred to carry out the reaction under acidic conditions.  Atmospheric, superatmospheric or subatmospheric pressures may be used. Substituted penta-alkoxy-pentanes, e.g. 2-methyl-1,1,3,5,5-pentaethoxy-pentane, may be used as tarting materials and the products are then substituted pyridines.  In the examples, pyridine is prepared by reacting 1,1,3,5,5 - penta - ethoxy-pentane with ammonia.

Abstract: 1, 049, 306. Pneumatic separation; cyclone separator. POLYSIUS G.m.b.H. July 30, 1965 [March 3, 1964], No. 32795/65. Addition to 1,018,020. Headings B2H and B2P. The classifier described in the parent Specification is modified by having an annular arrangement of guide blades in the region of the classifying-air inlets and a slidably movable ring for varying the entry cross-section for the air admitted between the guide blades. In one embodiment, Fig. 1, part or the whole of the classifying air is introduced through two volutes 15, 16, Fig. 2 (not shown), radially inwardly of which is mounted an annulus of adjustable guide blades 14. A ring 17 is mounted radially inwardly of the blades 14 and is vertically adjustable to vary the entry cross-section of the classifying air passing between the blades. In another embodiment, Fig. 3 (not shown); the ring 17<SP>1</SP> is mounted radially outwardly of the blades 14. The collecting funnel 7<SP>1</SP> for the fines forms the lower part of a cyclone whose upper part 21 is vertically adjustable and has a flared portion 21b in communication with the separating zone 13. The deflecting body 4<SP>1</SP> has an extension 4a projecting downwardly into the upper part of the cyclone. Blades 21a surrounding the extension 4a produce a swirling of the classifying air and entrained fines whereby the fines are separated by centrifugal action and discharged through the conduit 10<SP>1</SP> while the clean air is discharged through a central tube 23. The coarse particles collect in a chamber 24 which has a spirally-descending porous floor 25 and operates as a pneumatic conveyer trough.

Abstract: 605,067. Reamers. VICTORY ENGINEERS, Ltd., and FISHWICK, R. Dec. 5, 1945, No. 32945. [Class 83 (iii)] In an adjustable reamer having blades held between a pair of nuts at opposite ends of the shank, the ends of the blades are capable of being expanded or contracted simultaneously for reaming straight holes, or independently for reaming tapered holes. Three segments g, Figs. 2 and 3, are formed with helical cutting edges and have ends coned internally and externally. To increase the diameter of the segments equally at both ends, a coned locknut h, Fig. 5, is unscrewed on the left-hand thread b, Fig. 1, on the shank d by the required distance, as indicated by a micrometer scale l, and a sleeve p, Fig. 4, is screwed up the same distance on a right-hand thread c so that the internal cones on the segments ride up the taper f on the shank and the taper o on the sleeve; either the lock-nut h or another coned lock-nut i<SP>1</SP>, Fig. 7, screwed on the sleeve is then tightened to secure the segments in the adjusted position. By suitable adjustment of the locknuts and the sleeve, either end of the segments may be adjusted independently. Grooves r on the segments engage lugs.q on the shank to prevent relative rotational movement of the segments and the nut h has a counterbore n to give a long bearing on the plain portion of the shank.

Abstract: 775,068. Return tube steam boilers. BROWN FINTUBE CO. Nov. 23, 1955 [Dec. 2, 1954], No. 33585/55. Class 123(2) A return tube boiler comprises a shell 10 with end tube plates 12, 14 between which extends a combustion tube 15 having longitudinal external fins 20, the tube being of the form described in Specification 670,574. At the front of the boiler the end 16 of the tube 15 projects beyond the tube plate 12 and is fitted with an oil or gas burner 18. Hot combustion gases discharge from the rear end of the tube into a housing 23 whence they flow in the reverse direction through a bank of internally-finned tubes 30, of the form described in Specification 698,843, into a front housing 33 from which they discharge through a stack 35. A tube or shroud 54 welded to the tube plate 12 at one end and separated by a small gap 57 from the tube plate 14 at the other end, surrounds the tube 15. To increase the rate of heat transfer from the tube 15, a circulating pump 48 draws water from the upper portion of the boiler through a pipe 50 and discharges it through a pipe 52 together with the incoming feedwater delivered by a pump 41 into the annular space 60 adjacent the tube plate 12, the water flowing along between the shroud and the tube 15 and passing through the gap 57 into the main body of water in the shell. In a modification, Fig. 5, the pipe 52 is connected to a ring manifold 68 in the space 60, the manifold having a series of nozzles 69 which direct streams of water through the shroud tube, which in this case is disposed with its slightly flared front end spaced from the tube plate 12, the injector effect of the nozzles causing an internal circulation in the boiler shell.

Title: Improvements in or relating to the alkylation of paraffin hydrocarbons
Inventor: GANTT JAMES EDWARD
IPC: C07C9/16
Filed: 1957-10-29
Abstract: Isoparaffins are alkylated in the liquid phase in the presence of a hydrogen fluoride catalyst starting from a mixture of the isowith the corresponding n-paraffin in a process comprising mixing said mixture with a recycle isoparaffin-lean paraffin stream and fractionating in a first fractionation zone to obtain isoparaffin overhead and n-paraffin as bottoms, condensing the overhead and mixing with an olefine and an isoparaffin-rich recycle stream to form a reaction mixture containing at least 60 mol. per cent of isoparaffin and having mol. ratios of isoparaffin to olefin and n-paraffin of more than 4:1 and at least 3:1 respectively, reacting the mixture, separating the effluent into catalyst and hydrocarbon phases, the latter containing more than 55 mol. per cent of unreacted isoparaffin with dissolved catalyst, n-paraffin and product, passing this hydrocarbon phase into the top of a stripping zone from which is taken an overhead isoparaffin-rich stream containing dissolved catalyst which is condensed and recycled as said isoparaffin-rich recycle and a bottoms fraction which is fractionated in a second fractionation zone to obtain overhead an isoparaffin-lean paraffin stream which is condensed and recycled to the first fractionation zone and as bottoms, higher-boiling hydrocarbons containing alkylate product. The process is particularly suitable for the alkylation of isobutane with a C2-C6 olefine or a polymer of a gaseous olefine, particularly with butylenes.  A minor proportion of the stripping zone overhead is preferably stripped of hydrogen fluoride which is recombined with the stripping zone overhead and led, together with the reaction zone feed if so desired, to a fractionation zone where C3 and lighter hydrocarbons are removed, so that the concentration of propane and lighter components entering the reaction zone is maintanied constant at less than 3 mol. per cent.  The stripping zone bottoms are preferably defluorinated before passing to the second reaction zone, e.g. by passing through alumina, bauxite or aluminium rings. The hydrogen fluoride phase separated from the reaction zone effluent may be wholly or partly regenerated by fractionation and recycled.  The alkylation may be performed at - 18 DEG  to 93 DEG  C. and under sufficient pressure to maintain the liquid phase, e.g. 3.4-17 atmospheres.  The space time (volume of catalyst in the reaction zone divided by volume rate per minute of hydrocarbon feed) is preferably 5-15 minutes.  The catalyst which may be hydrogen fluoride alone or containing up to 10% of water or other additives such as boron trifluoride is used in a volume ratio to hydrocarbon of 0.5 to 5:1.
