CAS No.: 75-20-7
Molecular formula : CaC2
Molecular weight: 64.099
Density: 2.22
Melting point: 2160¡ãC
Boiling point: 2300¡ãC
Solubility: in water decomposes
Appearance: lumpy substance in deep gray, slight nasty
smell. It can produce acetylene gas when met water,
it can burn when met fire. The acetylene gas mix with
air will form
explosive gas ( explosive range of acetylene gas in
the air is 2.3%-81%.)
Applications:
Calcium carbide is mainly used industrially in the production
of acetylene and calcium
cyanamide. It is also used in steelmaking. In the ripening
of fruit, it is used as source
of acetylene gas, which is a ripening agent.
Specifications: gas yield: 285l/kg, 295l/kg, 305l/kg
size: 2-150mm
Packing: 100kg/ 200kg/ iron drum
Storage: Stored in dry, cool and draughty place. avoid
from other combustible and
explosive material.
UN No: 1402 Hazard Class: 4.3
