It has 355 isomers. It is used as a solvent, distillation chaser, and scintillator component. It is used as a diluent for tributyl phosphate (TBP) in reprocessing plants.[4] Combustion reactionThe combustion reaction of dodecane is as follows: C12H26(l) + 18.5 O2(g) → 12 CO2(g) + 13 H2O(g) ΔH° = −7513 kJ One litre of fuel needs about 15 kg of air to burn, and generates 2.3 kg (or 1.2 m3) of CO2 upon complete combustion. Jet fuel surrogateIn recent years, n-dodecane has garnered attention as a possible surrogate for kerosene-based fuels such as Jet-A, S-8, and other conventional aviation fuels. It is considered a second-generation fuel surrogate designed to emulate the laminar flame speed, largely supplanting n-decane, primarily due to its higher molecular mass and lower hydrogen to carbon ratio which better reflect the n-alkane content of jet fuels.
