  Lead chloride is a white crystalline powder

• Physikalische Eigenschaften

  White orthorhombic crystals; refractive index 2.199; density 5.85 g/cm³; melts at 501°C; vaporizes at 950°C; partially soluble in cold water (6.73 g/L at 0°C and 9.9 g/L at 20°C); KSP 1.17x10^-5 at 25°C; moderately soluble in boiling water (33.4 g/L at 100°C); slightly soluble in dilute HCl and ammonia; insoluble in alcohol.

• Occurrence

  Lead dichloride occurs in nature as the mineral cotunnite. The compound is used in making many basic chlorides, such as Pattison’s lead white, Turner’s Patent Yellow, and Verona Yellow, used as pigments. Also, it is used as a flux for galvanizing steel; as a flame retardant in nylon wire coatings; as a cathode for seawater batteries; to remove H2S and ozone from effluent gases; as a sterilization indicator; as a polymerization catalyst for alphaolefins; and as a co-catalyst in manufacturing acrylonitrile.

• Verwenden

  Lead(II) chloride is used in the synthesis of lead titanate and barium lead titanate ceramics; employed in the production of infrared transmitting glass and ornamental glass (aurene glass); useful as an electrode in geophysical applications and in solar cells. Analytical reagent, preparation of lead salts, as solder and flux. Pattinson's white lead, pigment in white paint, is the basic lead chloride.

• Definition

  ChEBI: An inorganic chloride consisting of two chlorine atoms covalently bound to a central lead atom.

• synthetische

  Lead dichloride is precipitated by adding hydrochloric acid or any chloride salt solution to a cold solution of lead nitrate or other lead(II) salt:
  Pb₂+ + 2Clˉ → PbCl₂
  Alternatively, it is prepared by treating lead monoxide or basic lead carbonate with hydrochloric acid and allowing the precipitate to settle.
  .

• Allgemeine Beschreibung

  Prepared by reacting lead(II) oxide /acetate or carbonate with HCl. In crystalline PbCl₂, each atom is coordinated by nine Cl atoms, six of which lie at the apices of a trigonal prism and the remaining three beyond the centers of the three prism faces. Each Cl is coordinated by four or five Pb atoms. Upon exposure to air it form basic chlorides such as PbCl₂.Pb(OH)₂.

• Reaktivität anzeigen

  Lead dichloride is a weak reducing agent. Interaction of Lead dichloride and calcium is explosive on warming, [Mellor, 1941, Vol. 3, 369].

• Hazard

  Toxic effects from ingestion may vary from low to moderate. The oral lethal dose in guinea pigs is documented as 1,500 mg/kg. (Lewis (Sr.), R. J. 1996. Sax’s Dangerous Properties of Industrial Materials, 9th ed. New York: Van Nostrand Reinhold).

• Health Hazard

  DUST AND FUMES. POISONOUS IF INHALED. SOLID: If swallowed, may cause metallic taste, abdominal pain, vomiting, and diarrhea.

• Brandgefahr

  Not flammable. POISONOUS METAL FUMES MAY BE PRODUCED IN FIRE. Toxic metal fumes. Can emit toxic metal fumes.

• Flammability and Explosibility

  Not classified

• mögliche Exposition

  Used to make lead salts; lead chromate pigments; as an analytical reagent for making other chemicals; making printed circuit boards; as a solder and flux.

• Erste Hilfe

  If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least 15 min, occasionally lifting upper and lower lids. Seek med-ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, includ-ing resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medi-cal attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Note to physician: Administer saline cathartic and alenema. For relief of colic, administer antispasmodic (cal-cium gluconate, atropine, papaverine). Consider morphinesulfate for severe pain. Whole blood lead levels, circulatingplasma/erythrocyte lead concentration ratio, urine ALA,and erythrocyte protoporphyrin fluorescent microscopy mayall be useful in monitoring or assessing lead exposure.Chelating agents, such as edetate disodium calcium (CaEDTA) and penicillamine (not penicillin), are generallyuseful in the therapy of acute lead intoxication.Antidotes cand special procedures for lead: Persons with sig-nificant lead poisoning are sometimes treated with CaEDTA while hospitalized. This “chelating" drug causes arush of lead from the body organs into the blood and kid-neys, and thus has its own hazards, and must be adminis-tered only by highly experienced medical personnel undercontrolled conditions and careful observation. Ca EDTA orsimilar drugs should never be used to prevent poisoningwhile exposure continues or without strict exposure control,as severe kidney damage can result.Note to physician: For severe poisoning BAL [British Anti-Lewisite, dimercaprol, dithiopropanol (C;HgOS2)] has beenused to treat toxic symptoms of certain heavy metals poi-soning. In the case of lead poisoning it may have SOMEvalue. Although BAL is reported to have a large margin ofsafety, caution must be exercised, because toxic effects maybe caused by excessive dosage. Most can be prevented bypremedication with 1-ephedrine sulfate (CAS: 134-72-5).

  Personal Protective Methods: W ear protective gloves andclothing to prevent any reasonable probability of skin con-tact. Use any barrier that will prevent contam ination fromthe dust. Safety equipment suppliers/manufacturers can pro-vide recommendations on the most protective g love/cloth-ing material for your operation. All protective clothing(suits, gloves, footwear, headgear) should be clean, avail-able each day, and put on before work. Work clothingshould be HEPA vacuumed before removal. Contact lensesshould not be wor when working with this chemical. Weardust-proof chemical goggles and face shield unless fullface-piece respiratory protection is worn. Employees shouldwash immediately with soap when skin is wet or contami-nated. Provide emergency showers and eyewash.

• läuterung methode

  Crystallise it from distilled water at 100o (33mL/g) after filtering through sintered-glass and adding a few drops of HCl, by cooling. After three crystallisations the solid is dried under vacuum or under anhydrous HCl vapour by heating slowly to 400o. The solubility in H2O is 0.07% at ~10o, and 0.43% at ~ 100o.

• Inkompatibilitäten

  A reducing agent. Violent reaction with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, and chemically active metals. Explosive with calcium 1 warming
