acetylene (əsĕt´əlēn´) or ethyne (ĕth´īn), HC[triple bond]CH, a colorless gas. It melts at -80.8°C and boils at -84.0°C. Offensive odors often noted in commercial acetylene are due to impurities. Acetylene forms explosive mixtures with oxygen or air. It is soluble in acetone, ethanol, and water. When dissolved in acetone it is nonexplosive and so is stored dissolved in acetone under pressure in steel cylinders for commercial use. Since it is explosive in the liquid state, it is not generally stored in this form. Acetylene is easily prepared commercially by the reaction of calcium carbide with water, but is prepared commercially by the pyrolysis of hydrocarbons. It is used for cutting and welding metals (see oxyacetylene torch) and is sometimes used as an illuminant gas. When subjected to high temperatures, it undergoes polymerization; benzene may also be formed. It is used in the production of many organic compounds, e.g., neoprene rubber, plastics, and resins. Acetylene is the simplest alkyne.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
