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:
“By many a legendary tale of violence and wrong, as well as by events which have passed before their eyes, these people have been taught to look upon white men with abhorrence.... I can sympathize with the spirit which prompts the Typee warrior to guard all the passes to his valley with the point of his levelled spear, and, standing upon the beach, with his back turned upon his green home, to hold at bay the intruding European.”
—Herman Melville (1819–1891)
“There is no reason why parents who work hard at a job to support a family, who nurture children during the hours at home, and who have searched for and selected the best [daycare] arrangement possible for their children need to feel anxious and guilty. It almost seems as if our culture wants parents to experience these negative feelings.”
—Gwen Morgan (20th century)
