什么东西燃烧时温度最高?例如乙炔燃烧可达3000度以上就是有没有比乙炔燃烧时温度还要高的燃料说出具体温度 少在这里抢分无聊的爬开 说具体点不要为了得分而回答无聊的我立马举报

氧炔焰据说可以达到3000°C

乙炔
化学式C2H2

燃烧时化学键断裂产生热！
越稳定的放热越多！铁燃烧应该更高

这个要看可燃质的客观条件了.

应该有吧。

当然有，比乙炔的碳原子多的就可以啊

肼，火箭的燃料。如果没有高的热值是不会选作火箭燃料的，它的燃烧温度可大3000-4000摄氏度。

吉尼斯记录是：
二氰乙炔在氧气中燃烧可以达到5260 K (4990 °C,9010 °F).
Dicyanoacetylene (also carbon subnitride,IUPAC but-2-ynedinitrile),C4N2,is a compound of carbon and nitrogen.It has a linear structure,NCCCCN,with alternating triple and single covalent bonds.In other words,it is acetylene with the two hydrogen atoms replaced by cyanide groups.
At room temperature,dicyanoacetylene is a clear liquid.Because of its high endothermic heat of formation,it can explode to carbon powder and nitrogen gas,and it burns in oxygen with a bright blue-white flame at a temperature of 5260 K (4990 °C,9010 °F),[1] which is the hottest flame of any chemical,according to Guinness World Records.
找到了一段话：
氧炔焰3000°C.
（CN）2 氰焰更高4525 °C (8180 °F)
这里提到4800K,
燃烧：
(CN)2 + O2 = 2CO + N2
Because of the high stability of the combustion products,CO and N2,the flame temperature can reach temperatures above 4800°K.Thus the cyanogen-oxygen flame is the hottest natural flame known.
这东西非常毒.
Cyanogen is the anhydride of oxamide:
H2NC(O)C(O)NH2 → NCCN + 2 H2O
制备
Preparation
Cyanogen is typically generated from cyanide compounds.One laboratory method entails thermal decomposition of mercuric cyanide:
2 Hg(CN)2 → (CN)2 + 2 HgCN
Alternatively,one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides,an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.[2]
2 CuSO4 + 4 KCN → (CN)2 + 2 CuCN + 2 K2SO4
Cyanogen is the chemical compound with the formula (CN)2
a much hotter oxyacetylene combustion at 3,000 °C.Cyanogen produces an even hotter flame with a temperature of over 4525 °C (8180 °F) when it burns in oxygen.[5]

估计是氢气吧。
