Technical specifications and features: Commodity name: calcium carbide Molecular formula: cac2 Cas number: 75-20-7 Un: 1402 Class: 4.3 Hs code: 28491000 Gas yield at 20 centigrade 101.3 kpa: ¡ý295l/kg Ph3(v/v): 0.08% H2s(v/v): 0.1% Molecular weight: 64.10 Size: 4-7, 7-15, 15-25, 25-50, 50-80, 80-120 mm Packing: 50kg or 100kg iron drum Application: Its main use industrially is in the production of acetylene gas. Cautions during transportation: The packing must be kept in good condition and the goods should be stored in a dry, cool and ventilated place. It should be separate from the cargo can burn and acid. It should avoid meeting water and moisture. It should give off the acetylene in iron drum before storing in warehouse. Rolling drums, heavy putting down and colliding are not allowed to avoid the spark leads to explosion. 50kgs or 100kgs per iron drum
