화학적 성질

Lead chloride is a white crystalline powder

물리적 성질

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.

출처

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.

용도

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.

정의

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

제조 방법

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.
.

일반 설명

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.

반응 프로필

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

위험도

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).

건강위험

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

화재위험

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

잠재적 노출

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.

운송 방법

UN2291 Lead compounds, soluble n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Purification Methods

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.

비 호환성

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
