| Observers have long known that Titan's atmosphere contains methane, ethane, acetylene and many other hydrocarbon compounds. |
| Less obvious and more tentative identifications include methyl cyanide, sulfur dioxide, acetylene. |
| Acrylonitrile is another product of acetylene, formed in a reaction with hydrogen cyanide. |
| Calcium carbide, made by reacting calcium oxide with carbon in the form of coke, is the starting material for the production of acetylene. |
| Firefighters were forced to retreat when they realised that the building contained acetylene canisters, gas bottles and diesel barrels. |
| Even dry-cleaning fluid, which is generally trichloroethylene, can be made from acetylene. |
