Acetylene

Acetylene (C₂H₂)

High-Reactivity Fuel and Chemical Building Block

Acetylene, a colorless, highly flammable hydrocarbon (C₂H₂), is the simplest alkyne with a distinctive triple carbon-carbon bond. This unique structure grants it unparalleled reactivity, making it a cornerstone in industrial and chemical processes. Acetylene is a widely used fuel gas, used for welding, brazing, cutting, and spot heating of metal surfaces. It is also used in the production of polyethylene plastics, rubber, dyes and pigments, pharmaceuticals, and pesticides. Supplied in acetone-dissolved cylinders for safe storage, our acetylene meets ISO 14175 standards with ≥99.6% purity and sulfur/phosphorus impurities<0.1 ppm.
