Audited Supplier C2H2 gas refers to acetylene gas, which is a colorless, highly flammable gas composed of two carbon atoms bonded to two hydrogen atoms (C2H2). It is commonly used in various industrial applications and has unique properties that make it useful in welding, cutting, and chemical synthesis. Here are some key points about C2H2 gas:
Properties: Acetylene gas is highly flammable and has a distinctive odor. It is lighter than air, so it tends to rise in the atmosphere. Acetylene gas is unstable and can decompose explosively when subjected to heat, pressure, or electrical sparks.
Production: Acetylene gas is primarily produced through the chemical reaction between calcium carbide (CaC2) and water (H2O) in a process called hydrolysis:
CaC2 + 2H2O → C2H2 + Ca(OH)2
This reaction generates acetylene gas along with calcium hydroxide as a byproduct.
Uses: C2H2 gas has several important applications:
Welding and Cutting: Acetylene gas is widely used as a fuel in oxyacetylene welding and cutting torches. When mixed with oxygen and ignited, it produces a high-temperature flame that can reach around 3,500 degrees Celsius (6,332 degrees Fahrenheit), suitable for melting and joining metals.
Chemical Synthesis: Acetylene gas serves as a versatile building block for the synthesis of various organic compounds. It is used in the production of plastics, solvents, pharmaceuticals, and other chemicals.
Lighting: Historically, acetylene gas was used in acetylene lamps for portable lighting. However, these lamps have largely been replaced by electric lighting systems.
Calibration Gas: Acetylene gas is sometimes used as a calibration gas in analytical instruments due to its well-defined properties and stability.
Safety Considerations: Acetylene gas is highly flammable and can form explosive mixtures with air. It should be handled with extreme caution, and proper storage, transportation, and handling procedures must be followed to minimize the risk of accidents. Acetylene gas cylinders should be stored in well-ventilated areas away from open flames, heat sources, and ignition sources.
When working with acetylene gas, it is crucial to adhere to safety guidelines, including using appropriate gas handling equipment, ensuring proper ventilation, and being aware of the risks associated with its flammability and potential for explosive decomposition.
It's important to handle and use C2H2 gas responsibly, following established safety protocols to ensure the protection of both personnel and the surrounding environment.

Specification:
Acetylene is used as a raw material for the production of electronically conducting plastics, such as polyacetylene.
Acetylene is used with high purity synthetic air or nitrous oxide as a fuel for the flame in atomic absorption flame spectroscopy. This is used in water, soil, food and biological research laboratories where sensitivity and accuracy of results are important.
Acetylene is most commonly used in combination with oxygen for cutting or welding materials such as mild steel, where the standard industrial grade is sufficient. Acetylene with low phosphine levels is required for lead brazing or welding.
Acetylene is used in organic synthesis (laboratory work) as well as in chemical synthesis.
Acetylene is used as carbon source in the production of molecular manufacturing like fullerenes; well known examples are bucky balls or carbon nanotubes.
Acetylene is used in th cultivation of plant; it improves the forming of new flowers.
Acetylene is used as a component in calibration gases for the gas, oil as well as chemical industry.
Acetylene is still used in some lighthouses as light fuel source.
Acetylene is one of the components in lung testing gases.
