Barking dog reaction : ウィキペディア英語版 | Barking dog reaction
The "Barking Dog" is an exothermic chemical reaction that results from the ignition of a mixture of carbon disulfide and nitrous oxide.〔''Taming the Barking Dog '' Seabourne, Ché Royce; Maxwell, George; Wallace, James. J. Chem. Educ. 2006 83 751. (Link )〕 It has been known for centuries; in 1853, Justus von Liebig was using the bright blue flash and the distinctive ‘woof’ sound of the demonstration to enthrall his students. In simple terms, the ‘Barking Dog’ reaction is a combustion process, in which a fuel (carbon disulfide, CS2) reacts with an oxidizing agent (nitrous oxide, N2O), producing heat and elemental sulfur. The flame front in the reaction is a zone of very hot, luminous gas, produced by the reactants decomposing. 8 N2O + 4 CS2 → S8 + 4 CO2 + 8 N2 ==References==
