    Specific and immediate action is required with any acetylene cylinder. IF. The contents gauge shows a pressure higher than kPa. The cylinder is heated accidentally. The cylinder becomes unduly warm. There is any sign of smoke; There is an unusual smell with gas discharged. An explosion occurs in the regulator or hose. Buy Online Then. Acetylene is a colorless, flammable gas, with a garlic-like odor, that is dissolved in acetone. See the Acetylene page under the Pure Gases Tab on the Menu of our Specialty Gas & Equipment Catalog for detailed information of gas purity.

    Acetylene Acetylene (C 2 H 2). Acetylene is a colorless and tasteless gas with a garlic-like odor. It is flammable and can be an asphyxiant. It is one of the fuel gases used in oxy-fuel gas welding, which is any welding procedure that combines a fuel gas with oxygen to produce a flame. Acetylene (C 2 H 2) is the simplest alkyne (hydrocarbons that have a triple bond between two carbon atoms, with the formula C n H 2n−2).Under standard conditions in the laboratory, it is a colorless but unstable gas. Because of its symmetry, linear of the form HCCH, it lacks a permanent electric dipole moment and hence has no allowed pure rotational transitions, making it undetectable at.

      Acetylene gas features properties that make it an extremely useful gas in various applications and industries. Acetylene is mainly manufactured for chemical synthesis. The second most common application of acetylene is welding and cutting. Commercial Uses of Acetylene. Acetylene forms an important part of many crucial processes in industries. Acetylene is a moderately common chemical in the universe, often associated with the atmospheres of gas giants. One curious discovery of acetylene is on Enceladus, a moon of Saturn. Natural acetylene is believed to form from catalytic decomposition of long-chain hydrocarbons at temperatures of 1, K (1, °C; 2, °F) and above. Since.

The absorption spectrum of acetylene has been recorded using high sensitivity cavity ring down spectroscopy (α min ~5×10 −11 cm −1) in the – cm −1 interval corresponding to a weak absorption CRDS spectra revealed new bands which were identified on the basis of a global effective Hamiltonian model (Lyulin OM, Perevalov VI, Teffo JL.
