Title: Nitric acid acidulation of phosphate rock
IPC: C01B33/10
Filed: 1963-03-12
Abstract: <PICT:1037303/C1/1> Phosphoric acid is obtained by acidulating fluorine-containing calcium phosphate solids, e.g. phosphate rock, with at least a stoichiometric quantity of boiling, i.e. at 60-130 DEG  C. depending on pressure, nitric acid.  The nitric acid may be of 40-70% concentration, and acidulation takes place in the presence of added finely-divided silica, e.g. one half to one part silicic acid finer than 100 mesh for every one to two parts fluorine in the rock, so that the fluorine content of the reaction mixture may be reduced to less than 2%, based on the starting phosphate, by volatilizing as SiF4 or HF.  From the acidulation vessel 10, the reaction mixture is passed via a separator 22, where sand and slime are removed, to vessel 26 where crystallization of Ca(NO3)2.4H2O takes place on cooling to - 15 DEG  C. This is removed in separator 30, residual Ca is precipitated with H2SO4 in vessel 34 and removed in separator 3.8 Nitric acid used to wash the precipitates is returned to acidulation vessel 10 via pipe 14. The phosphoric acid liquor, preheated in 44 DEG  to 50-60 DEG  C., is concentrated at 100 mm. Hg or less in the vacuum stripping system 42, and phosphoric acid containing 55-72% P2O5 and less than 1% nitric acid or combined fluorine passes out through pipe 51.  SiF4 and HF in the nitric acid-water vapour from acidulation vessel 10 is precipitated in vessel 54 as Na2SiF6 or K2SiF6 using Na2CO3 or KOH maintained a 100% excess.  The HNO3, concentrated in vessel 52, returns to vessel 10 via pipe 16. The HNO3 volatilized in vacuum system 46 may also be concentrated in vessel 52 after removal of residual fluorine compounds in 54 if necessary.  Alternatively it may be recovered by direct condensation in the system 72, using recycled cooled nitric acid.

Title: Improvements in or relating to the manufacture of ketene
IPC: C07C45/88
Filed: 1936-04-02
Abstract: In the production of ketene by pyrolysis of e.g. acetone, acetic acid, acetic anhydride or acetaldehyde, the pyrolysis vapours are cooled substantially to their dew point and the cooled vapours passed through a condenser in which the condensed ketene-forming compound <PICT:0472988/IV/1> flows in countercurrent to the incoming vapours. Acetone from tanks 1 or 2 is pumped through a copper tube 4 heated to 760--810 DEG  C.  The issuing vapours are cooled in coil 5 to their dew point, i.e. about 54 DEG  C., and pass to vessel 7 surmounted by a water-jacketed reflux condenser 6 and connected to tank 2 by line 14.  The condensed acetone is maintained in the vessel 7 at about 56 DEG  C. and is withdrawn continuously to a rectifying column 11 from the top of which pure acetone is taken off for re-circulation.  High boiling constituents are drawn off at 20. Ketene passes by pipe 18 for example, to an absorption column 8 and absorbers 15.

Abstract: PURPOSE:To prevent leakage of secret of confidential documents through copying, by making objects in such a way that the color contrast between the ground of paper and characters and graphs written on the paper can be discriminated by naked eyes but hardly discriminated by lights for copying. CONSTITUTION:An object 9 is a sheet of vermilion color 8, on which characters 2, graphs, etc., are printed in black, and the black characters, etc., can be read by naked eyes against the vermilion color of the ground. When the object 9 is put on a PPC copying machine and a copying light 4 for forming electrostatic image is irradiated upon the object 9, the contrast between the ground color and the color of characters, etc., is very inferior and the characters 2 cannot be read. Therefore, the copy 10 of the object 9 has a black ground 11 for the whole surface by the toner. Thus the object 9 cannot be copied. In this way leakage of secrets of confidential documents through copying can be prevented.
