The last valency of carbon is completed by the electron lost by calcium. Calcium carbide's formula is CaC2 because in this the two carbon atoms have a triple bond with each other. Aluminum carbide (Al4C3) Tetraaluminium tricarbide. Pure calcium carbide is colorless, but most of the material is produced industrially, and is somewhat impure, giving it a black or grayish-white color, depending on the quality. A convenient source of acetylene, C2H, is a compound incorrectly called "calcium carbide," which suggests a formula of Ca C, composed of two Ca2+ ions and a Ct-ion. 12656-43-8. Its main use industrially is in the production of acetylene and calcium cyanamide. ALUMINUM CARBIDE, Al4C3. Reacts violently with water liberating highly flammable gas (acetylene). 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.

This section provides a listing of alternate names for this chemical, SAFETY DATA SHEET Calcium Carbide SDS No. Near this site lived Thomas Leopold “Carbide” Willson (1860-1915), discoverer of the commercial process for making calcium carbide, which reacts with water to form acetylene gas. To produce accurate results, the reagent must react with all the water which is not chemically hydrated with soil minerals or compounds in the soil. Absorption of water during handling or storage of technical calcium cyanamide may … CopyCopied, InChI=1S/C2.Ca/c1-2;/q-2;+2 Calcium carbide [Wikimedia] Cal­ci­um car­bide has great prac­ti­cal sig­nif­i­cance. (USCG, 1999). National Oceanic and Atmospheric Administration. Calcium carbide is introduced from the top of the generator shell into the water. Used to make acetylene and in steel manufacture. Behavior in Fire: If wet by water, highly flammable acetylene gas is formed. 00. Reacts violently or explosively with water. UN1394. [C-]#[C-]. General molecular orbital energy level diagrams are provided below. INHALATION OF DUST: remove from further exposure and call a doctor. Incompatible with moisture, water, strong oxidizing agents, alcohols, Calcium cyanamide can also be produced from this compound by reacting it with nitrogen at relatively high temperatures. Aluminum carbide, powder, ~325 mesh, 95%. Commercial Calcium Carbide, however, may present a relatively wide range of colors depending on the impurities present (usually calcium, magnesium and other oxides). Grayish-black irregular lump solid. Safety glasses, good ventilation. Aluminum carbide,al4c3. Depending on the calcium carbide content, the cyanamide reacts with water (moisture from air or soil) to produce acetylene and hydrated calcium oxide or calcium hydroxide. 1 decade ago. 5, 862].
