Patent GB-719601-A (GB)
Title: Dehydrochlorination of polychlorocyclohexanes
IPC: C07C17/25
Filed: 1952-10-15
Abstract: Polychlorocyclohexanes such as benzene hexachloride are dehydrochlorinated to give mixtures of isomeric polychlorobenzenes by contacting the polychlorocyclohexane at an elevated temperature, e.g. 180 DEG -350 DEG  C. with an anion exchange resin. Preferably the reaction is carried out at 220 DEG -250 DEG  C. in the presence of 0.01 per cent to 4 per cent of the resin.  Many types of anion exchange resin are specified.  Dehydrochlorination of benzene hexachloride according to the invention produces 1 : 2 : 4- and 1 : 2 : 3-trichlorobenzene.  In an example benzene hexachloride is heated at 250-270 DEG  C. in the presence of an "Amberlite" (Registered Trade Mark) anion exchange resin to give trichlorobenzenes; similarly dehydrochlorination of monochlorobenzene hexachloride and dichlorobenzene hexachloride gives tetrachlorobenzene and pentachlorobenzene respectively.  A comparative experiment using powdered iron as a catalyst in place of an anion exchange resin is described.

[Class 144 (ii)] [Also in Group V] A cushion tyre, of the kind described in Specifications 368,562 and 399,356, comprises integral circumferential and transverse partitions in which the latter extend to the wheel rim and are slotted to provide a continuous circumferential passage of small cross-section open to the atmosphere through apertures in the rim. Figs. 1 and 3 show one form of tyre and mould-core, the latter consisting of a ring 6 with radial webs 4 for spacing the transverse partitions in the tyre, the webs being slotted to provide the circumferential partitions 5. Beads 14 on the core provide the base-slots 13 in the transverse partitions, and an additional web 7 is formed on the core to facilitate its withdrawal. The division produced by the web 7 may be closed after removal of the core, as by vulcanization indicated at 11. In modifications, some or all of the circumferential partitions may extend to the rim, in which case additional venting-channels are provided in the transverse partitions. The cells may be of any desired shape in cross-section, Figs. 5 and 6, showing a tyre with cells 18 of rounded section spaced by partitions 19 all of which extend to the rim, the circumferential venting-apertures being indicated at 16a. Fig. 14 shows a further modification in which the transverse partitions are formed with strengthening ribs 29 produced by the recessed portions 30 in the slotted webs 4 of the core shown in Fig. 10. The core-webs may be profiled to vary the thickness of the partitions, especially at the tread-junctions of the circumferential partitions and the base-portions of the transverse partitions. To facilitate removal of the cores, these may be of asymmetric form, as illustrated in Fig. 19, to produce a tyre of the cross-section shown in Fig. 17. Fig. 22 shows a further modification, stated to be particularly applicable for use on rail vehicles, in which some of the cavities, as shown at 43, 45, 46, are open at the sides and treadportion of the tyre.

Examples describe the preparation of the chromiferous dyestuff and the dyeing of wool therewith.  Specification 310,011, [Class 2 (iii)], is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of other chroming agents (e.g. chromium acetate or fluoride) and the chroming of dyestuffs in which the naphthalene nucleus of the coupling component contains additional substituents (other than sulphonic acid groups), such as alkyl or alkoxy groups or especially halogen atoms, e.g. the dyestuffs obtained from 6- or 7-methoxy-, 5 : 8-dichloro-or 5 : 8-dibromo-2-naphthol.  It is stated that the products are suitable for dyeing or printing silk, leather, staple fibres of casein, animalized cellulose artificial silk and superpolyamides.
