Title: A process for the preparation of aromatic nitriles
IPC: C07D213/16
Filed: 1964-01-20
Abstract: Aromatic nitriles are made by the reaction of a nitrogen oxide halide, and (or) a mixture of a nitrogen oxide and a halogenating agent, in the presence of a tertiary amine, or an aromatic compound substituted in the nucleus with a group having the structure -CH2R or a structure tautomeric therewith, R representing a hydrogen or halogen atom or a methyl or nitroso group.  Thus, the group -CH2R may represent a methyl, ethyl, chloromethyl or bromomethyl group or a nitrosomethyl group or the oximinomethyl group (-CH:NOH) tautomeric therewith.  The aromatic compound may be of the benzene, naphthalene, phenanthrene or biphenyl series and may be further substituted by halogen atoms or nitro, cyano, alkoxy, carbalkoxy or higher alkyl groups.  If the starting material is a nitroaromatic compound the reaction may involve the replacement of a nitro group by a halogen atom, as in the examples below.  The nitrogen oxide halide may be a nitrosyl halide or a nitryl halide.  The nitrogen oxide may be nitric oxide, nitrogen trioxide or nitrogen peroxide.  The halogenating agent may be a free halogen which may be formed in situ, e.g. from hydrogen chloride or a mixture of hydrogen chloride and nitric acid. Other specified halogenating agents are sulphuryl chloride, phosphorus pentachloride, thionyl chloride and N-bromosuccinimide. The preferred tertiary amines, which may be used in only catalytic proportions, are pyridine and its homologues, but other heterocyclic tertiary amines are also specified.  The reaction may be effected at 120-240 DEG  C. at atmospheric, reduced or raised pressure in the presence or absence of a solvent, a number of which are specified, the gaseous nitrogen oxide halide, or a gaseous mixture of a nitrogen oxide and halogen, preferably being brought into contact with the molten or dissolved aromatic compound. Water is preferably removed from the reaction mixture as it is formed, and the mixture may be irradiated with ultra-violet light.  Examples are given in which 2,6-dichlorobenzonitrile and minor amounts of 2,6-dichlorobenzal chloride, 2,6 - dichlorobenzyl chloride and 6-chloro-2-nitrobenzonitrile are produced from 6-chloro-2-nitrotoluene under various reaction conditions.  An example is given also of the production of 2,6-dichlorobenzonitrile from 2,6-dichlorobenzyl chloride. Other specified starting materials are toluene, p-xylene, 2- and 4-nitrotoluene, 2,4-dinitrotoluene, 6-chloro-2-methoxytoluene, 6-bromo-2 - nitrotoluene and 6 - chloro - 2 - nitrobenzyl chloride.

In a gas-cooled nuclear reactor, each stand pipe leading to a fuel element channel is sealed with a biological shield plug which is mechanically locked and provided with electrical contacts to indicate the positions of the lock components. Thermocouple leads pass through the plug from the fuel elements. As shown, the plug 6 is locked in the standpipe 2 by the balls 10 and sealed by rings 8, 9. To withdraw the plug vertically upwards from 2 the bolt 21 is urged downwards by the spring 23, upon pressure equalisation at the plug upper surface by the refuelling machine. With 21 at its lowest position, the ball 10 registers with the recess 24 and moves radially inwards. The sleeve 16 is then pulled upwards relative to the plug part 6 by the hoisting members 61, 62, 63 and the balls 10 are withdrawn from grooves 5 into grooves 14. Spring 17 is compressed and plug 6 finally moves upwards. The separation of contacts 48, 49 indicate the movement of 16 from the locked position. The corrections of controls 70 and 45 indicates that the safety lock is free and the movement of 21 downwards from the locking position is indicated by the separation of contacts 44, 69. Specification 897,446 also is referred to.

Abstract: 648,339. Closet-seat guards. GERADTS, L. M. E. J. H., and TROMP, G. M. Jan. 29, 1948, No 2723. Convention date, Jan. 30, 1947: [Class 26] A closet-seat is mounted to be depressed under load and is furnished with means for feeding paper or other protective material in strip form over the rim of the seat as a consequence of the automatic rising of the seat when the load is removed, mechanism being provided for cutting off used material during each such operation of the seat. The material may cover the the front of the seat, or it may be fed over each side of the rim, separate feeding means and cutting mechanism being provided for each side. The depression of seat 1 causes the cutting edge 11 of a lever 6 to coact with a knife 12 to cut off any part of the strip P hanging beyond the said knife 12. The outer extremity of the lever 6 engages a projection of a pivoted segment in which is a recess, the teeth on one side of which engage a pinion to rotate a rod 19 to wind a coiled spring 21 surrounding and connected at its inner end to the rod 19, the outer end being secured to a cylindrical housing 22 enclosing the spring and attached to a supporting plate 20 for the rod 19. A sleeve 23 freely rotatable on the rod 19 carries a ratchet-wheel at one end cooperating with a pawl 25 (not shown) pivotally mounted by means of a bolt surrounded by a distant-piece 27 to keep the said wheel and pawl co-planar, and at the other end has secured to it a friction roller 4 with a rubber surface 5. The portion of the rod 19 in the roller 4 is of larger diameter and has a recess 28 containing a pin 30 and a spring 29 to function as a pawl, the presence of which in the deeper part of the recess 28 causes the friction roller 4 to remain stationary, and hence the sleeve 23. The ratchet-wheel on the sleeve 23 is engaged by the pawl 25 when the lever 6 has turned sufficiently. The seat rises under the action of a spring 7, and after sufficient turning of the lever 6 the pawl 25 (not shown) is caused to disengage the ratchet-wheel, the spring 21 is thus unwound, the rod 19 is rotated so that the roller 4, now coupled with the pivot 19 by the pawl 30, rotates to bring fresh material P over the seat.
