• 用途

  合成中間体

• 説明

  Calcium phosphide has the molecular formula of Ca3P2 and the molecular weight of 182.1825 g/mol. Its CAS number is 1305-99-3. It is a red-brown crystalline material with a melting point of 1605°C. Its density is 2.51 g/cm³. It readily reacts with water to form phosphine, PH3, but is insoluble in ethanol.
  It is easily prepared by reacting the metal with red phosphorus at high temperature. The best way is to sublime the P4 at 450°C in an inert gas stream and react it with Mg metal at 750°C:
  6Ca + 2P4?2Ca3P4

• 化学的特性

  Calcium phosphide is a gray granular solid or reddish-brown crystalline solid. It has a musty odor, somewhat like acetylene.

• 使用

  Metal phosphides, primarily Ca3P2, have been used as rodenticides. Calcium phosphide baits have strong, pungent garlic-like odor characteristic for phosphine liberated by hydrolysis. The odor attracts rodents, but has a repulsive effect on other animals, who are not receptive to the smell. This salt has uses in incendiary bombs and other explosives. On contact with acids or water, calcium phosphide releases phosphine, which ignites spontaneously. It is also used in fireworks, torpedoes, self-igniting naval pyrotechnic flares, and various water-activated ammunition.

• 一般的な説明

  CALCIUM PHOSPHIDE appears as red-brown crystals to gray granular lumps. CALCIUM PHOSPHIDE reacts with water to form calcium hydroxide and phosphine, a flammable poisonous gas. Phosphine will normally ignite spontaneously in contact with air. If there is an excess of water this fire of phosphine will not normally ignite surrounding combustible material.

• 反応プロフィール

  CALCIUM PHOSPHIDE and hydrochloric acid undergo a very energetic reaction [Mellor 8:841 1946-47]. Calcium and other alkaline earth phosphides incandesce in oxygen when heated.

• 危険性

  Dangerous fire risk; decomposed by water to phosphine, which is highly toxic and flammable. See phosphine.

• 健康ハザード

  Inhalation or ingestion causes faintness, weakness, nausea, vomiting. External contact with dust causes irritation of eyes and skin.

• 火災危険

  Behavior in Fire: Can cause spontaneous ignition if wet. Contributes dense smoke of phosphoric acid.

• 安全性プロファイル

  Highly toxic due to phosphde, which in presence of moisture emits phosphine. The phosphine may ignite spontaneously in air. Incandescent reaction with oxygen at 300°C. Incompatible with dichlorine oxide. When heated to decomposition it emits toxic fumes of POx. See also CALCIUM COMPOUNDS and PHOSPHIDES.

• 職業ばく露

  A strong reducing agent. Forms spontaneously combustible phosphine gas in moist air. Contact with water or acids release phosphine gas, and can cause explosions. Incompatible 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, chlorine monoxide, halogens, halogen acids, oxygen, sulfur

• 輸送方法

  UN1360 Calcium phosphide, Hazard Class: 4.3; Labels: 4.3-Dangerous when wet material

• 不和合性

  A strong reducing agent. Forms spontaneously combustible phosphine gas in moist air. Contact with water or acids release phosphine gas, and can cause explosions. Incompatible 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, chlorine monoxide, halogens, halogen acids, oxygen, sulfur
