English description（英文原文，共 1398 字符）
Product Name:High Purity Acetylene
English Name:High Purity Acetylene
CAS No.:74-86-2
Aliases:Calcium carbide gas, Dissolved acetylene
Molecular Formula:C2H2
Physical Properties:Colorless, highly flammable gas at room temperature and atmospheric pressure; molecular weight 26.04; slightly soluble in water, soluble in ethanol, diethyl ether and acetone. Industrial-grade product may have a characteristic pungent odor due to impurities such as hydrogen sulfide and phosphine. Triple point temperature: -80.8°C; sublimation point at atmospheric pressure: -84°C; gas density: 1.17 kg/m³ (0°C, 101.325 kPa); relative density (air=1): 0.91. Chemically active, prone to addition and polymerization reactions; extremely flammable, flame temperature can reach above 3000°C; explosive limits in air: 2.3%–80.7% by volume.
Uses:Widely used for metal welding and cutting (oxy-acetylene flame) and as a key raw material for organic synthesis, producing acetaldehyde, acetic acid, vinyl chloride, vinyl acetate, acrylic acid and other chemical products. High-purity acetylene is also used in semiconductor device manufacturing, optical fiber preparation, and as a calibration standard gas in analytical laboratories.
Technical Specifications:
Purity (C2H2) ≥99.99%
Oxygen (O2) content ≤10 ppm
Nitrogen (N2) content ≤50 ppm
Moisture (H2O) content ≤5 ppm
