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]
