Title: Process for the production of beads or bead-like granules from molten or heat plastified thermo-plastic polymeric material and apparatus therefor
IPC: B29C48/30
Filed: 1960-01-12
Abstract: 880,055. Pelletting plastic materials. DOW CHEMICAL CO. Jan. 12, 1960 [Jan. 15, 1959(2)], No. 1031/60. Class 87(2). A process of making pellets from plastic material comprises extruding the heat plastified material into a confined space which is open on opposite sides and ejecting the material from the space, with simultaneous coding, by introducing a compressed inert material into the space. Details of various solid and cellular composition are given and the compressed inert material may be gaseous or liquid, e.g. water, steam, nitrogen, propane or methyl alcohol. In Fig. 1 a screw extrudes plastic material through peripheral slots 27 in a screw extension 13 that is forced by the pressure of the material against a die member 14. The bearing face of the extension 13 has an annular groove 31 and radial grooves 30. The die member 14 has stepped outlets 24 and an inlet 23, for the inert material, which connects with the grooves 31, 30. As the screw and extension 13 rotate the material passes through the slots 27 in to the outlets 24 until the slots 27 and outlets 24 are out of register, continued rotation of the extension 13 brings the grooves 30 in register with the outlets 24 so that the inert material passes through the inlet 23, grooves 31 and 30 and ejects the plastic material from the outlets 24. The grooves 27 and outlets 24 may have different circumferential pitches to avoid pulsation of the plastic material and inert material. In Fig. 8, a discharge member 36 with outlets 37 rotates around a stationary die member 34 having longitudinal slots 35 and surface grooves 38 leading to groover 39 in the discharge member 36 and a inert material inlet 40. In operation the material is extruded through the slots 35 into the outlets 37 whose rotation brings them over the grooves 38 so that the inert material from the inlet 40 grooves 39 and 38 may eject and cool the pellets. The die has a cleaning outlet 43 uncovered by a plug 42 and the discharge member is rotated by a sprocket 52. The outlets 24, 37 may be of any cross-sectional shape. U.S.A. Specification 2,453,088 is referred to.

Title: Improvements in and connected with alkylation and aralkylation of carbazol
IPC: C07D209/86
Filed: 1923-01-12
Abstract: Alkyl and aralkyl derivatives of carbazole are prepared by direct treatment with the alkylating &c. agent in presence of a dehydrating agent, such as powdered or granular caustic alkali, with or without a solvent, and at ordinary or raised temperatures. The solvents mentioned as suitable are solvent naphtha, chlorbenzene, toluene and steam-distilled kerosene.  The apparatus employed may be of iron or glass and is fitted with a reflux if a solvent be used.  The proportions preferred are 2.5 gram-molecules of caustic alkali in the form of 20 mesh particles and one litre of solvent to one gram-molecule each of carbazole and alkylating agent.  According to an example, toluene, carbazole, and granular or powdered caustic soda are charged into an iron kettle fitted with a steam-jacket and reflux, diethylsulphate stirred in and the temperature raised to 85 DEG  C. The temperature is allowed to rise and finally the mixture is boiled for about an hour.  The toluene is then removed by steam distillation and the ethylcarbazole washed free from alkali and salts with water, or the washing may take place first.  In either case the product is finally separated by cooling when it will solidify and may be recrystallized from ethyl alcohol.  In the Specification as open to inspection under Sect. 91 (3) (a), the use of quicklime as a dehydrating agent for the reaction is also referred to, and it is stated that the aryl derivatives of carbazole may be similarly prepared.  This subject-matter does not appear in the Specification as accepted.

Title: Synthesis of hexafluorobenzene
Inventor: BARBOUR ANTHONY KENNETH
IPC: C07C17/26
Filed: 1961-02-20
Abstract: Hexafluorobenzene is obtained by pyrolysing dichloromonofluoromethane at 500 DEG  C. to 700 DEG  C., cooling the products to a liquid form, deacidifying the liquid product, e.g. using an alkaline solution, and separating the hexafluorobenzene from the liquid product.  The pyrolysis is desirably carried out in a heated corrosion-resistant tube for a period of 1 to 30 seconds.  The tube may be packed or unpacked and constructed of a noble metal, e.g. platinum, or silica. The reaction is generally carried out at atmospheric pressure, although higher and lower pressures may be used.  The reactants may be diluted with an inert gas, e.g. helium or nitrogen, and hydrogen may also be introduced into the reaction tube to minimize side reactions. The pyrolysis yields, in addition to hexafluorobenzene, trichlorofluoromethane, symmetrical dichlorodifluoroethylene, symmetrical tetrachlorodifluoroethane, pentafluorobenzene, polychloropolyfluorobenzenes and other compounds as yet unidentified but probably comprising polychloropolyfluoro - butanes, - butadienes, -hexanes and -hexadienes.  The hexafluorobenzene may be isolated from the reaction products by fractional distillation or gas-liquid chromatography.  Reference has been directed by the Comptroller to Specification 936,610.
