Sicherheit

Calcium carbide Chemische Eigenschaften,Einsatz,Produktion Methoden

  • ERSCHEINUNGSBILD GRAUE KRISTALLE ODER SCHWARZE STüCKE MIT CHARAKTERISTISCHEM GERUCH.
  • ARBEITSPLATZGRENZWERTE TLV nicht festgelegt (ACGIH 2005).
    MAK nicht festgelegt (DFG 2005).
  • AUFNAHMEWEGE Aufnahme in den Körper durch Inhalation.
  • INHALATIONSGEFAHREN Verdampfung bei 20°C vernachlässigbar; eine gesundheitsschädliche Partikelkonzentration in der Luft kann jedoch schnell erreicht werden, vor allem als Pulver.
  • WIRKUNGEN BEI KURZZEITEXPOSITION WIRKUNGEN BEI KURZZEITEXPOSITION:
    ätzend. Die Substanz verätzt die Augen, die Haut und die Atemwege. Inhalation der Substanz kann zu Lungenödem führen (s.Anm.).

  • Chemische Eigenschaften grey or black solid with a garlic-like odour
  • Verwenden used as desulfurizer and dehydrant of steel and for cutting and welding metals.?in organic synthesis industry, Acetylene obtanied from calcium carbide is raw material to make ethylene, chloroprene rubber, calcium cyanamide, acetic acd, acetaldehydr, ethylacetate, cyanide acetate, dicyandiamide, acetone, octanol, trichloride ethylene etc
  • Verwenden Generating acetylene gas for lighting purposes (1 kg of carbide yields ~300 liters acetylene); as reducing agent, e.g., for direct reduction of copper sulfide to metallic copper; signal fires for marine service; manufacture of calcium, iron, alloys, lampblack, cyanamide; welding and cutting metals.
  • Verwenden It is used to produce acetylene gas in numerousapplications. Also, it is used as a reducingagent to produce metals from their salts.
  • Verwenden Calcium carbide (CaC2) has a garlic-like odor and reacts with water to form acetylene gas plus calcium hydroxide and heat. In the past, it was used in miners’ lamps to continuously produce a small acetylene flame to provide some illumination in coal mines.
  • Allgemeine Beschreibung Grayish-black irregular lump solid. Used to make acetylene and in steel manufacture.
  • Air & Water Reaktionen Reacts rapidly with water to generate the flammable gas acetylene and the base calcium hydroxide. Enough heat may be generated to ignite the gas [Jones, G.W. BM Report Invest. 3755 1944].
  • Reaktivität anzeigen Calcium carbide is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862]. The carbide burns incandescently when mixed and heated with lead difluoride, magnesium, hydrogen chloride, and tin (II) chloride, [Mellor, 1946, 1940, 1946, and 1941], respectively. Interaction of Calcium carbide with methanol to give calcium methoxide is vigorous , but subject to an induction period of variable length. Once reaction starts, evolution of acetylene gas is very rapid, unpublished observations [Bretherick 1995]. Mixing Calcium carbide with silver nitrate solutions forms silver acetylide, a highly sensitive explosive. Copper salt solutions would behave similarly, [Photogr. Sci. Eng., 1966, 10, 334]. The mixture of Calcium carbide and sodium peroxide is explosive, as is Calcium carbide and perchloryl fluoride as gases at 100-300°C.
  • Hazard Forms flammable and explosive gas and corrosive solid with moisture.
  • Health Hazard It is a corrosive solid. Because it is highlywater-reactive, skin contact can cause burn.
  • Health Hazard Eye and skin irritation
  • Brandgefahr Behavior in Fire: If wet by water, highly flammable acetylene gas is formed.
  • Sicherheitsprofil Reaction on contact with moisture forms explosive acetylene gas. Flammable on contact with moisture, acid or acid fumes; evolves heat or flammable vapors. Moderate explosion hazard. Incandescent reaction with Cl2 (245℃), Brz (350℃), IS (305℃), HCl gas + heat, PbF2, Mg + heat. Incompatible with Se, (KOH + Ch), AgNO3, Na2O2, SnCl2, S, water. Mixtures with iron(IⅡ) chloride, iron(IⅡ) oxide, tin(Ⅱ) chloride are easily ignited and burn fiercely. Vigorous reaction with methanol after an induction period. Addttion to silver nitrate solutions precipitates the dangerously explosive silver acetylide. Copper salt solutions behave similarly. See also CALCIUM HYDROXIDE and ACETYLENE.
