Product name:Calcium Carbide (Desulfurization) Particle size: 0.5-5mm CAS NO.:75-20-7 Density: 2.22 g/mL at 25 °C(lit.) Storage temp: water-free area Water Solubility: hydrolyses Sensitive: Moisture Sensitive Calcium Carbide Sort：Calcium Carbide / Desulfurization Detail： Gas Released (L/KG) ≥： 285 PH3Content in Acetylene(V/V)%≤： 0.08 H2SContent in Acetylene(V/V)%≤： 0.10 Particle SIZE (mm)： 10–80 Specificity： Grey ,black solid ,purple when its purity is more than 90%,thespecificgravityis2.32(purity80%),melting point 1980oC(purity 52.5%).It ca dissolve in water to create acetylene and calcium hydroxide and heat will be released at the same time. Usage： It is a basic material in organic synthesis industry ; acetylene obtained from calcium carbide is the raw material to make ethylene, chloroprene rubber ,calcium cyanamide , acetic acid ,acetaldehyde ,trichloroethylene ,etc . Also used as desulfurization agent in steel industry and for metal cutting and welding.
