Title: Improvements in and relating to recovery of non-staining pyrethrins
Inventor: ISRAEL WILLIAM OSBORNE
IPC: A01N65/00
Filed: 1962-10-03
Abstract: Non-staining pyrethrins are obtained from crude extracts of pyrethrum flowers by mixing with at least an equal weight of anhydrous methanol at above 35 DEG  C., cooling to below 15 DEG  C. to precipitate a waxy residue, separating and washing the residue with anhydrous methanol, decolorizing the dewaxed methanol solution with activated carbon, and distilling the methanol from the solution.  If desired, a filter aid can be added before precipitating the waxes, filtering the wax-coated filter aid and washing with methanol.  If no filter aid is used the waxes are washed with methanol at least three times at above 35 DEG  C.  The methanol is distilled preferably below 50 DEG  C. at subatmospheric pressure and in the presence of a high boiling solvent, e.g. hydrocarbons or piperonyl butoxide.  Final purification is achieved by dissolving in hexane, and cooling to below - 10 DEG C. to precipitate the resins, separating and concentrating the solution in the presence of a high boiling carrier solvent.

Title: Improvements in or relating to the recovery of hydrogen fluoride from its azeotrope with water
Inventor: BROOKS LIONEL HEPWORTH
IPC: C01B7/19
Filed: 1958-11-27
Abstract: <PICT:0881532/III/1> HF is recovered from its azeotrope with water (37% HF) by contacting vapour of the azeotrope mixture with a metallic oxide maintained at a temperature to form metal fluoride with the HF while steam does not react, and raising the temperature of the metal fluoride in contact with steam to liberate HF and regenerate the metallic oxide.  The steam for the regeneration may be that separated in the first stage, or that present in more vapour mixture.  Oxdies may be ferric, cupric, chromic, or nickel oxides. Azeotrope vapour enters tower 1 containing ferric oxide 2 and maintained at 170 DEG  C. at 3 and steam passes to waste through 4. When the ferric oxide in tower 1 is exhausted, azeotrope vapour is also passed through 10 to tower 11 containing ferric oxide 12 and maintained at 170 DEG  C. with steam passing to waste at 4 through 13. At the same time tower 1 is raised to 550 DEG  C. and the ferric oxide is regenerated by steam in the azeotrope vapour from 3, while liberated HF is passed through 6 to fractioning column 7, whence anhydrous HF is withdrawn at 8 and azeotrope mixture is returned to 3 through 9.  When the ferric oxide in tower 11 is exhausted, the functions of the towers are reversed and tower 11 is regenerated with HF vapour passing to column 7.
