• 일반 설명

  LEAD PHOSPHITE, DIBASIC is a finely ground white crystalline solid. LEAD PHOSPHITE, DIBASIC is not soluble in water. LEAD PHOSPHITE, DIBASIC may be toxic by ingestion or skin absorption. The material can be readily ignited from exposure to heat or external sparks. When so ignited LEAD PHOSPHITE, DIBASIC burns vigorously and persistently.

• 공기와 물의 반응

  Insoluble in water.

• 반응 프로필

  LEAD PHOSPHITE, DIBASIC is self-reactive. A fiber drum of lead diphosphite caught fire apparently without any external cause. A gradual decomposition appears to have taken place, yielding lead phosphate, water, and phosphine. Phosphine , in turn, is spontaneously flammable in air and was probably the ignition source for the resulting fire [Kirk and Othmer 10:489. 1947]. Reacts violently with hydrogen sulfide [Bretherick 1979. p. 977-978].

• 건강위험

  Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

• 화재위험

  Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.
