Acetylene is used with high purity air of nitrous oxide as a fuel for the flame in atomic absorption)flame spectroscopy This is used in water and biological research laboratories where sensitivity and accuracyiof 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"1s required for lead brazing or welding.Acetylene is used in organic synthesis (laboratory work) as well as in chemical synthesis.This unsaturated hydrocarbon exhibits high chemical reactivity, and is an important intermediate in the chemical industry.
