Title: Oxytetracycline esters and preparation thereof
IPC: C07C233/00
Filed: 1965-08-02
Abstract: The invention relates to tetracycline compounds having the formulae <FORM:1100884/C2/1> <FORM:1100884/C2/2> <FORM:1100884/C2/3> wherein A is -CH3 or YSCH2, Y being primary or secondary C1-C12 alkyl; R11CO(R11 bein C1-C3 alkyl); phenyl; mono- or di-substituted phenyl; benzoyl; -CF3; or R1CH2 (R1 being mono- or di-substituted C1-C6 alkyl, C1-C6 carbalkoxy, halo, phenyl, mono- or di-substituted phenyl, or furyl); each substituent of mono- or di-substituted alkyl being C1-C6 alkoxy, C1-C6 carbalkoxy or halo and when two substituents are on the same carbon, at least one is C1-C6 carbalkoxy; and each substituent of mono- or di-substituted phenyl being C1-C6 alkyl, alkoxy or carbalkoxy, or nitro; and wherein B is hydrogen; or wherein A with B is methylene; and wherein R1 is alkanoyloxy, phenoxyalkanoyloxy or C1-C6 alkoxy-alkanoyloxy, in which the alkanoyloxy groups are C2-C6; and acid addition or metal salts, and metal salt complexes of these compounds.  The compounds, which are O5-monoacyl oxytetracyclines, and also the corresponding O12a-acyl derivatives of the compounds (i.e. O5,O12a-diacyl oxytetracyclines), are prepared by treating the corresponding O12a-monoacyl oxytetracycline or the corresponding O10,O12adiacyltetracycline, or a metal salt thereof, in aqueous solution with at least one equimolar proportion of alkali metal hydroxide, or in alcoholic solution with alkali metal alcoholate, to effect a re-arrangement of the acyl groups. The product may be treated, inert solvent, with one equivalent of acid, metallic base, or metal salt to give the corresponding salt or complex.  The reaction temperature is preferably between 0 DEG  and 50 DEG  C. Dedradation of the esters may be minimized by conducting the reaction in the presence of 1 to 2 equivalents of a solvent-soluble polyvalent metal salt, e.g. salts of Ca, Mg, Zn, Cd, Cu, Ni or Co, and preferably magnesium chloride hexahydrate, many other suitable Mg salts being listed.  The products are isolated by adjusting the reaction mixture pH to 2-7 and extracting with an immiscible solvent, e.g. ethyl acetate.  When a polyvalent metal is present, the product may be recovered as the metal-ester complex, which is precipitated by adjusting the pH to 6-8.  Additional processes mentioned are catalytic hydrogenation of the inventive products, under acid conditions with a palladium catalyst, to give the corresponding epimeric 6-deoxy-oxytetracyclines; also Raney nickel desulphurization of the benzylmercaptan adducts to give a -6-deoxy-oxytetracycline esters; mild acid treatment, e.g. with saturated methanolic HC1 to effect dehydration to 5a,6-anhydro-O5acyl oxytetracyclines; and formation of mixed esters by further esterification of the inventive compounds.  Preparations of starting materials, i.e. O12a - monoacyl - and O10,O12a - di - acyl oxytetracyclines, are described, involving esterification of the mono-esters with this anhydride in pyridine, and hydrolysis of appropriate di-esters to the corresponding mono-esters with ammonium hydroxide.

Patent GB-820918-A (GB)
Title: Improved method and apparatus for the manufacture of artificial threads by melt-spinning
IPC: D01D1/06
Filed: 1957-10-24
Abstract: <PICT:0820918/IV (a)/1> <PICT:0820918/IV (a)/2> In melt-spinning artificial threads by supplying a fusible filament-forming polymer in particulate form to a heated melting grid and pumping the melt thereby obtained to a spinneret plate by means of a heated pump block or unit, the pump block is maintained in a heated condition when the melting grid is replaced by another.  As shown in Fig. 1, granular polymer from a rigidly mounted feed hopper drops through a rotary valve 36, a guide tube 39 and a fall pipe 9 on to a melting grid 1 which comprises an annular jacket 2 connected through nipples 3, 4 (Figs. 1 and 2) with a heating device (not shown) and with a spiral tube 5 in such a manner that a heating fluid circulates through the jacket and the spiral tube.  The polymer melted on the grid falls into a collecting hopper 12 in the jacket 2 and flows through an outlet 15, inlet 20 and suction line 21 to the spinning pump 22 in the pump block 18.  Thence it is pumped through the pump discharge pipe 23 and sand filter 24 and is extruded through the spinneret plate 25.  The pump block 18 is surrounded by a heating jacket 26 through which extends the pump shaft 27.  The hopper 12 (the walls of which may be solid, instead of hollow, as shown) has a flat underface 16 which mates with the flat upper face 17 of the pump block 18 to permit heat transfer between the hopper 12 and the pump block.  The outlet 15 of the hopper 12 is so dimensioned that the melt only just flows out of the hopper under its own weight. When the melting grid 1 has become fouled with polymer deposits the valve 36 is closed and spinning is continued until the hopper 12 is empty, whereupon the pump drive is switched off.  Next the bolts 19 holding together the melting grid 1 and the pump block 18, and the bolts 34 holding together the flange 33 and the flange 35 of the rotary valve, are unscrewed and removed.  As a result the flange 33 descends freely, as the upper portion 31 of the fall pipe 9 is a rubber sleeve, and the melting grid 1 rests freely on the pump block 18.  The grid may then be removed, after bolts 10 have been unscrewed and removed, and is immediately replaced by a clean grid which preferably has been preheated.  The apparatus is then bolted up, air is expelled from pipe 9 by connecting the nipple 11 with a supply of nitrogen and the pipe 9 is refilled with granular polymer by opening valve 36. Spinning is then resumed as soon as the hopper 12 becomes refilled with melt. During the replacement of the fouled melting grid 1 by a clean grid, the pump block with the pump remains in situ and is uninterruptedly maintained at the spinning temperature.

Divided out of 421,048. [Class 7 (iv)] [See also Group XXXVI] The one-piece casing is lined throughout with mica 8 within which is pressed a metal block 9 supporting the central electrode 10. A bush 26, clamped to the outer end of the casing by a metal ferrule 27, is concave-ended and externally threaded to engage a metallic casing or shield 28, the main part of which extends at right angles to the plug. The casing is lined with mica 28<a>, an aperture being provided for the passage of a conductor 23 enclosed in a third mica sleeve 25. An air space separates the sleeve 25 from the washers 12. The conductor 23 engages a spring washer upon the end of the central electrode, and at its outer end threads into a block 32. The other end of the block is split, and the parts are expanded by a screw 32<y>, to grip the mica sleeve 28<a>.

The ends of the discharge tubes of a gas switch extend into cylindrical cavities in the conducting walls of the switch which, together with the plasma enclosed in the tubes, form coaxial line wave-traps for preventing escape of energy. In Fig. 1, a non-metallized discharge tube 1 is shown extending into the wall 3 of the switch to form a coaxial line of length L of which the dielectric consists partly of the wall 4 of the tube and partly of the cylindrical air gap 2. The length L is made equal to an odd number (preferably one) quarter-wavelengths. The end of the tube rests on an insulating plug 5 located by a screw-threaded plug 6. In a modification (Fig. 2), the effective end of the line is formed by the open end of an annular choke slot 10, 11 and the line has an effective length D. In a further modification (Fig. 3, not shown), the air gap 2 is filled with metal braid whereby the dielectric of the coaxial line is composed entirely of the material of the tube.
