Patent GB-648689-A (GB)
Title: Process for separating components of fluorination reaction mixtures by distillation
IPC: C01B7/19
Filed: 1947-07-30
Abstract: <PICT:0648689/III/1> The mixture obtained by reacting carbon tetrachloride with hydrogen fluoride is submitted to fractional distillation under a pressure in the range 40 to 200 pounds per square inch (gauge), the temperature of the dephlegmator being within the range - 63 DEG  to - 20 DEG  C. so as to take off pure hydrogen chloride vapours; the distillation-residue is then subjected to fractional distillation under a pressure in the range 0 to 100 pounds per square inch, the temperature in the dephlegmator being within the range - 32 DEG  to +30 DEG  C. so as to take off a vapour mixture comprising difluorodichloromethane (CCl2F2) and hydrogen fluoride. This vapour mixture is condensed, and the condensate is allowed to settle and form two layers-one layer is predominantly CCl2F2 containing a minor proportion of dissolved HF, and the other layer is predominantly HF containing a minor proportion of dissolved CCl2F2. The separated CCl2F2 layer is washed with water to remove HF. p Carbon tetrachloride and hydrogen fluoride are passed in the predominantly liquid state to reaction-vessel 10 which contains as catalyst a mixture of antimony pentachloride and trichloride which has been previously treated with HF.  The reaction mixture is passed through reflux-column 12 and dephlegmator 14 which are operated to retain CCl4 and CCl3F so as to obtain maximum conversion to CCl3F2. The products are freed from antimony salts in catch-tank 16, and are then compressed into the middle of reflux-column 20 maintained under a pressure of about 100 pounds per square inch.  Dephlegmator 22 is maintained at a temperature in the range - 40 DEG  to - 50 DEG  C. so as to take off pure hydrogen chloride overhead, while still-pot 18 is heated to a temperature in the range 25 DEG -30 DEG  C.  The residue in still-pot 18 is forced by autogeneous pressure into reflux-column 26 where a pressure of about 40 pounds per square inch is maintained. Dephlegmator 28 is held at a temperature in the range 0 DEG  to 5 DEG C.; and a mixture of CCl2F2 and HF is taken-off overhead, and condensed in condenser 29.  The condensate is passed to settling-tank 30 where separation into two layers takes place. The predominantly CCl2F2 layer is withdrawn from tank 30 and passed to a scrubber to be washed free of HF.  The HF layer is withdrawn and passed to reaction-vessel 10.  The residue in still-pot 24, which comprises CCl3F and CCl4, is also returned to the reaction-vessel.  In an alternative method of operation, the residue from still-pot 18 may be passed to a settling-tank to form an HF layer and an organic layer which can then be separated.  The organic layer is then submitted to fractionation.

Title: Improvements in the purification of industrial zinc sulphate solutions preparatory to electrolysis
IPC: C25C1/16
Filed: 1926-08-23
Abstract: 269,776. Stevens, R. H., Norris, G. C., and Watson, W. N. Aug. 23, 1926. Zinc sulphate. - The precipitation of nickel from zinc sulphate solutions, preparatory to electrolysis of the latter, by the addition of zinc dust to the neutral or slightly acid and preferably heated solution in which soluble copper and arsenic compounds are present is effected in the absence of substances, and especially of organic substances, foreign to the necessary steps for the original dissolving of the zinc and the, preliminary purification of the sulphate solution by neutralization with a basic material. The same conditions are preferably observed during the separation of the resulting precipitate from the solution. The invention is particularly applicable to sulphate solutions obtained by leaching zinc ores. To carry the invention into effect, the use of canvas, wool, hemp, coal tar bitumen. and of teak, pine, or other timbers in the apparatus employed for obtaining and purifying the solution is avoided as by using apparatus which exposes only lead surfaces to the solution; care is taken that lubricants, such as cup grease, applied to the bearings of the apparatus, cannot enter the solution; and the use of reagents, such as tar oil, wattle tar oil, alkali zanthate, oxalic acid, glue, turpentine, sodium acetate, soap, resin, or eucalyptus oil, which are normally used for floatation or other purposes in the treatment of the ore, leach residue, or solution, is either avoided, or care is taken that the reagents used are removed or destroyed prior to the nickel precipitation step. If necessary, the solution must also be clarified, e.g. to remove suspended silica or alumina which has passed through the filter at a previous filtration step, and steps should be taken to prevent the ingress of flying insects into the treatment vessels.
