Key Applications
- Metal Fabrication
- Oxy-acetylene welding/cutting: Delivers a 3,100°C flame (hottest gas flame), enabling precision joining and slicing of steel alloys.
- Thermal spraying: Prepares metal surfaces for corrosion-resistant coatings.
- Chemical Synthesis
- Vinyl chloride monomer (VCM): Produced via HCl addition, serving as the precursor for PVC plastics.
- Organic intermediates: Synthesizes acetaldehyde, acetic acid, and pharmaceuticals like vitamin A.
- Specialized Uses
- Lab-scale reactions: Facilitates alkyne metathesis and cycloadditions in R&D.
- Portable lighting: Powers underground/mining lamps (historical niche).
Safety & Compliance
- Explosive range: 2.5–81% in air (strictly NFPA-compliant handling protocols)
- Non-toxic but asphyxiant in confined spaces.
- Available with traceable SDS and DOT/ADR-certified packaging.
