Lead(II) carbonate basic Usage And Synthesis
  • Solubility in water(g/100ml)Dissolved grams per 100 milliliters of water:
    7.269 × 10-5/20 °C Toxicity
  • Chemical propertiesWhite powder, hexagonal crystal system. It is insoluble in water and ethanol, and soluble in acetic acid and nitric acid. Gamma-Butyrolactone
  • UsesLead carbonate basic has a high refractive index and weather fastness, widely used in pigments, coatings, plastics, printing and dyeing, analysis reagents, etc .; for pigments, it is used for excellent pearlescent pigments; and it is also used to produce inorganic pigments with paint and pigments. In the printing and ink, it is used for packaging paper, business cards, plastic cloth, textiles and so on. As the possibility of leading to lead poisoning in the production and application, and the vulnerability to thicken when the paint is made by white lead, and the whiteness easily declining when contact with and hydrogen sulfide and other shortcomings, its application is limited. While the coating film produced by the lead white is more stable, with excellent weather resistance and rust resistance. In the paint industry, it is still used as the white pigments for the production of the original paint, anti-rust paint and outdoor paint; raw materials for ceramic glaze, painting and cosmetic; amino or acrylic baking finish of coating. Add 2% to 8%. It is used in painting with cars, motorcycles, bicycles, furniture and so on. In plastic, basic lead carbonate can be used as vinyl chloride plastic stabilizer for the production of pearlescent plastic, pearlescent paint and so on.
  • Preparation1. Chemical method: adding carbon dioxide, deionized water into reaction solution prepared by lead acetate, lead oxide and deionized water. After reaction, then by precipitation, added with nitrocellulose pulp slurry, precipitation, crystallization, centrifugal dehydration, washed with alcohol, drying, the basic lead carbonate is obtained. Alcohol waste liquid is treated and recovered. The reaction equation is: Pb(Ac)2+PbO+H2O→Pb(Ac)2•Pb(OH)2;
    3[Pb(Ac)2•Pb(OH)2]+2CO2→3Pb(Ac)2+2PbCO3•Pb(OH)2+2H2O
    2. Acetic acid method: mix yellow lead, acetic acid and water together in the mother liquor tank, and the concentration of the mixture of lead oxide is 230~250 g/L. Suspend the mixture with stirring; keep warm for 3h in the 90 ℃  leading to the formation of basic lead acetate; clarify and carbonize with purified carbon dioxide; when 85% lead hydroxide in the basic lead acetate is carbonized, that is the end of the reaction; and then by precipitation, centrifugal separation, with oil and alcohol washing and drying, basic lead carbonate products is made. In addition, the separated mother liquor can be recycled. The reaction equation is: 2PbO + 2HAc → Pb (Ac) 2 • Pb (OH) 2
    3[Pb(Ac)2•Pb(OH)2]+2CO2→3Pb(Ac)2+2PbCO3•Pb(OH)2+2H2O.
  • ToxicityEarly symptoms of poisoning is that lead linear appearing in the edge of the gums and urinary poisoning. For chronic poisoning, it has changes in the nervous system, the emergence of debilitating syndrome, encephalopathy, dysmotility, changes in the blood system, metabolic and endocrine disorders, gastrointestinal changes and changes in the cardiovascular system.
    A maximum allowable concentration of lead and lead inorganic compounds is 0.01 mg/m3 and 0.0007 mg/m3 in an average working day.
    When the poisoned suffered colic, he should receive subcutaneous injection of atropine, morphine, and intravenous injection of magnesium sulfate, sodium thiosulfate, calcium chloride. Masks blocking 95% to 97% of lead dust is allowable when working; when in the environment of high vapor concentration, you can use the filter gas mask for a forced supply of fresh air. When the poisoned ones suffered colic, he should receive subcutaneous injection of atropine, morphine, and intravenous injection of magnesium sulfate, sodium thiosulfate, calcium chloride.
