Title: Improvements in or relating to the regeneration of vulcanised synthetic rubber-like materials
IPC: C08J11/20
Filed: 1943-06-24
Abstract: Vulcanized synthetic rubber-like materials of the type produced by the polymerization of butadiene, its homologues or substituted derivatives, either alone or together with styrene or acrylonitrile, are plasticised by being mechanically disintegrated, treated with a mixture of a softening agent, a plasticiser having a mercapto grouping and an organic acid of the aromatic group and then converted to a coherent sheet by mechanical working between rolls.  The synthetic rubber is first reduced sufficiently to pass a 20 mesh per inch sieve by passing through grinding rolls having a high friction ratio (e.g. 5 : 1) and is then added to a warm mixture consisting of 2-20 per cent of a softener such as pine tar, pine oil, a coumarone resin, naphthenic acid or a salt thereof such as zinc or iron naphthenate, 1/2 -5 per cent of an organic acid of the aromatic group such as salicylic acid, benzoic acid, o-, m- or p-nitrobenzoic acids, a dinitrobenzoic acid or a halogen substituted benzoic acid, with the addition of 1/4 -2 per cent of a plasticising agent containing the mercapto group such as mercaptobenzthiazole or a - or b -naphthyl mercaptan, and thoroughly stirring till a uniform mix is obtained. The mixture is then allowed to stand for 2-3 days at ordinary temperatures or for a shorter time at an elevated temperature and is then milled between rolls having a friction ratio of 1.2-3 : 1 till a coherent sheet is formed, the rolls being kept below 60 DEG  C. at this stage by water cooling if necessary.  The temperature is then raised to 90-100 DEG  C. for a short period in order further to increase the plasticity.  In a typical mix, 100 parts of synthetic rubber tyre tread crumb are added to a mixture of 10 parts coumarone resin, 3 parts benzoic acid and 1 part of mercaptobenzthiazole.  The treated product may be used alone or with the addition of natural or synthetic rubber.  Specification 558,334 is referred to.  According to the Provisional Specification, the plasticiser may be omitted. Specification 564,514 is referred to in the Provisional Specification.

Patent GB-449710-A (GB)
Title: Improvements in or relating to the conversion of carbon disulphide to sulphur
IPC: C01B17/04
Filed: 1935-04-05
Abstract: Sulphur is obtained by heating carbon disulphide with sulphur dioxide in the presence of a catalyst comprising a compound of titanium, thorium, uranium, cerium, silicon, tungsten or vanadium, specified in the order of decreasing activity.  Mixtures of the above compounds may be used, together with promoters and/or carriers.  The catalyst may be used in the form of sulphide; oxide or other compounds readily converted to sulphide, except silicon which remains as the oxide. The carbon disulphide and sulphur dioxide are preferably mixed in equimolecular proportions, the reaction being initiated at temperatures of 180--250 DEG  C., and carried out at temperatures up to 450 DEG  C., at substantially atmospheric pressure.  Sulphur dioxide may be obtained from pyrites or fouled iron oxide used for gas purification, or a portion of the sulphur produced may be burnt to sulphur dioxide. Large concentrations of water vapour should be avoided, owing to the formation of hydrogen sulphide, and the carbon disulphide should be freed from hydrocarbons owing to poisoning of the catalyst.  In an example, the catalyst used is titanium sulphide or titanium hydroxide obtained by precipitation with ammonia from the chloride.  It may be used in the solid form or on a support, and the reaction is carried out at 250 DEG  C. under atmospheric pressure.
