分子结构和有关的化学性质对物质的自然温度有着重大的影响。分子结构简单的气体和挥发气,其点火温度比较高。举例来说,氢(H_2)的点火温度为560℃,甲烷(CH_4)为595℃,一氧化碳(CO)为605℃,氨(NH_3)为630℃。化学性能稳定的物质,其自燃温度也高。以苯(C_6H_6)为例,它的六分晶系环特别稳定,自燃温度为560℃。正已烷(C_6H_14)的自燃温度为233℃。
The molecular structure and related chemical properties have a significant effect on the natural temperature of matter. The molecular structure of simple gas and volatile gas, the ignition temperature is relatively high. For example, the ignition temperature of hydrogen (H 2) is 560 ℃, methane (CH 4) is 595 ℃, carbon monoxide (CO) is 605 ℃ and ammonia (NH 3) is 630 ℃. Chemical stability of the material, its auto-ignition temperature is also high. To benzene (C_6H_6), for example, its six-crystalline ring is particularly stable, auto-ignition temperature of 560 ℃. The auto-ignition temperature of n-hexane (C_6H_14) was 233 ℃.
