Definitions

  • a process for producing a particulate precipitated aragonite calcium carbonate, and the particulate precipitated aragonite calcium carbonate thus produced comprises reacting an aqueous calcium hydroxide slurry with a gas selected from the group consisting of carbon dioxide and a gas containing it, wherein the parameters of said process, including at least one preselected active agent, mode of operation, operating concentrations of raw materials, operating temperature, operating mixer speed and operating pH, wherein said at least one active agent is selected from nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, tetradecanoic acid, octadecanoicacid, and undecylenic acid, their carboxylate salts, their acid anhydrides, their esters, their acyl halides and their ketenes.
  • this threshold concentration discussed above, for catalyzing the production of particulate precipitated aragonite, of the present invention ( ⁇ 0.2% wt.%, based on CaCOs) is substantially above the threshold concentration that is required to cause the flotation of this product in aqueous solutions ( ⁇ 0.02% wt.%, based on CaCOs) and that by operating in the concentration range merely for a "proper" flotation process, nothing that is disclosed in the present invention really happens.
  • the optimal physical and chemical properties of the particulate precipitated aragonite calcium carbonate, of the present invention are attained at above 100 fold of this concentration ( ⁇ 2-3 wt.%, based on CaCOs).
  • the first 10 I. of resulting slurry were discarded.
  • the residual slurry was collected and it was filtered through a filter-cloth on the Buchner using a vacuum pump to dewater the product.
  • the filter cake was dried for 12 hours at 120°C and the crystallographic morphologies and the shapes of the crystals of the precipitated calcite and/or aragonite calcium carbonate particles were determined using XRD and SEM analyses, respectively. The results are shown in the Table 1 , below.
  • the active agents were investigated by producing precipitated calcium carbonate particles according to the following procedure:
  • the resulting slurry was filtered through a filter cloth on the Buchner using a vacuum pump to dewater the product.
  • the filter cake was dried for 12 hours at 120°C and the crystallographic morphologies and the shapes of the crystals of the precipitated calcite particles were determined using XRD and SEM analyses, respectively. As mentioned above, no precipitated aragonite particles were obtained.
  • Rotor Speed 4800 rpm (Tip Speed ⁇ 12 m/sec).
  • pH variable.
  • Temperature 87°C.
  • Carbon dioxide flow rate 180 L.P.H. (liters/hour)
  • Aqueous calcium hydroxide slurry (of Shfeya) -10 wt.% ⁇ 6 L.P.H. (to maintain the preset pH value).
  • Active agent concentration decanoic acid; 0.5 wt.% based on CaCO 3 .
  • Active agent concentration decanoic acid; 1 wt.% based on CaCO 3 .
  • Active agent concentration decanoic acid 1 wt.% based on CaCO 3 .
  • Aqueous calcium hydroxide slurry (of Shfeya) -10 wt.% - 6 L.P.H. (to maintain the preset pH value).
  • Cellosize QP 15000 thickener (hydroxy ethyl cellulose).
  • Copolymer vinyl acetate acrylate (55% N.V.) (emulsion).
  • particulate precipitated aragonite calcium carbonate of the present invention (PCC-Aragonite) is not yet optimized for its use in the production of paints and though the formulations used are by no means optimized, still this product is able to substitute over 50% of the expensive titanium oxide pigment without any deterioration of the resulting paint, as it manifested by the hiding power measured.
  • Aqueous calcium hydroxide slurry (of Shfeya) -10 wt.% ⁇ 6 L.P.H. (to maintain the preset pH value).
