Abstract: Low molecular weight fractions and/or catalyst residues are removed from polymers of mono-1- olefins which have been made by bulk polymerization using Zeigler-Natta type catalysts by contacting the effluent, i.e. polymer, monomer, and catalyst residues, with a complexing agent for the catalyst residues under liquid phase conditions in a contacting zone in which the effluent is heated in a first section of the zone to increase the complexing reaction, and cooled in a second section to a temperature sufficient to increase the extraction of low molecular weight fractions therefrom, washing the effluent from the contacting zone in a wash zone, wherein low molecular weight polymer fractions are removed, and recovering the solid high polymer from the slurry in the wash column. The 1-olefin may be ethylene, propylene, 1-butene, 1-pentene, or 3-methyl-1-butene. The complexing agent is preferably diacetylacetone mixed with propylene oxide.

Abstract: Ammonium fluoride and silica are produced by interacting an aqueous fluosilicic acid solution, which may contain up to 4 moles of ammonia per mole of fluosilicic acid, and aqueous ammonia at a temperature between the freezing point of the solution and 40 DEG C, such that a pH greater than 7.5 is maintained throughout the reaction. Sufficient ammonia may be introduced into the reaction vessel before the addition of the fluosilicic acid solution or insufficient may be initially introduced and the remainder introduced during the addition of the fluosilicic acid.  The temperature is preferably below 30 DEG C. and the pH is preferably greater than 8.  The aqueous ammonia may have a concentration of 5-29 per cent.  The fluosilicic acid may have a concentration of 5-25 per cent, preferably 12-20 per cent.  The silica produced may be separated by filtration or settling.  The resulting ammonium fluoride solution may be freed of excess ammonia by heating or reduction of pressure.  Ammonium hydrogen fluoride may be prepared by evaporating the ammonium fluoride solution at 100-130 DEG C.  The fluosilicic acid may be obtained by absorbing in water or dilute ammonia the silicon tetrachloride containing gases evolved during the production of phosphates by treatment of phosphate rock, with sulphuric acid.  These gases may first be purified by scrubbing with 70-98 per cent sulphuric acid or 18-34 per cent fluosilicic acid.  Any solid material present in the fluosilicic acid in spite of the scrubbing treatment may be separated before reaction with the ammonia.  When using sulphuric acid as scrubbing liquor, the spent liquor may be used for the production of superphosphate.
