LEAD HYDROXIDE C화학적 특성, 용도, 생산
화학적 성질
white powder(s) [CRC10]물리적 성질
White amorphous powder; density 7.41 g/cm3; dehydrates above 130°C and decomposes at 145°C; slightly soluble in water, 155 mg/L at 20°C; KSP 1.42x10-20 at 25°C; soluble in dilute acids and alkalies; insoluble in acetone and acetic acid.용도
Lead hydroxide is used in making porous glass; in electrical-insulating paper; in electrolytes in sealed nickel-cadmium batteries; in recovery of uranium from seawater; and as a catalyst for oxidation of cyclododecanol.제조 방법
Lead dioxide is produced by oxidizing an alkaline slurry of lead monoxide with chlorine, sodium hypochlorite, or bleaching powder. Alternatively, it is obtained by passing chlorine into a hot aqueous suspension of lead sulfate and magnesium hydroxide. The ionic reaction is:Pb(OH)3ˉ +ClOˉ → PbO2 + Clˉ+ OHˉ + H2O
It also is produced by electrolysis of acidic solutions of lead salts using a lead or platinum electrode. In such electrolytic process, lead dioxide is deposited on the anode of the cell.
Insoluble powdered lead dioxide also may be obtained when lead tetroxide is heated with nitric acid:
Pb3 O4 + 4HNO3 → 2Pb(N)3)2 + PbO2 + 2H2O
Lead dioxide also can be prepared by fusing lead monoxide with a mixture of sodium nitrate and sodium chlorate.
