Autoignition Point of Selected Substances
Temperatures vary widely in the literature and should only be used as estimates. Factors which may cause variation include partial pressure of oxygen, altitude, humidity, and amount of time required for ignition.
- Triethylborane: −20 °C (−4 °F)
- Silane: <21 °C (70 °F)
- White phosphorus: 34 °C (93 °F) (ignites on contact with an organic substance, melts otherwise)
- Carbon disulfide: 90 °C (194 °F)
- Diethyl ether: 160 °C (320 °F)
- Diesel or Jet A-1: 210 °C (410 °F)
- Gasoline (Petrol): 246–280 °C (475–536 °F)
- Butane: 405 °C (761 °F)
- Paper: 450 °C (842 °F) or 218–246 °C (424–475 °F)
- Magnesium: 473 °C (883 °F)
- Hydrogen: 536 °C (997 °F)
For paper, there is considerable variation between sources, partially because it takes longer for the combustion of paper to start at lower temperatures.

Famous quotes containing the words point and/or selected:
“The ellipse is as aimless as that,
Stretching invisibly into the future so as to reappear
In our present. Its flexing is its account,
Return to the point of no return.”
—John Ashbery (b. 1927)
“She was so overcome by the splendor of his achievement that she took him into the closet and selected a choice apple and delivered it to him, along with an improving lecture upon the added value and flavor a treat took to itself when it came without sin through virtuous effort. And while she closed with a Scriptural flourish, he “hooked” a doughnut.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
