Dodecane

<h2 id="combustion-reaction">Combustion reaction</h2>
<p>The combustion reaction of dodecane is as follows:
</p>
C12H26(<i>l</i>) + 18.5 O2(<i>g</i>) → 12 CO2(<i>g</i>) + 13 H2O(<i>g</i>)
<a href="/facts/Enthalpy/bBou8lCE">Δ<i>H</i>°</a> = −7513 <a href="/facts/Joule/9ndq9jD2">kJ</a>
<p>One litre of fuel needs about 15 kg of <a href="/facts/Air/6IyFHIpG">air</a> to burn (2.6 kg of oxygen), and generates 2.3 kg (or 1.2 m3) of CO2 upon complete combustion.
</p>
<h2 id="jet-fuel-surrogate">Jet fuel surrogate</h2>
<p>In recent years, <i>n</i>-dodecane has garnered attention as a possible <a href="/facts/Fuel_surrogate/bfYML2Ya">surrogate</a> 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 <a href="/facts/Laminar_flame_speed/40a23jhk">laminar flame speed</a>, largely supplanting <i>n</i>-decane, primarily due to its higher molecular mass and lower hydrogen-to-carbon ratio which better reflect the <i>n</i>-alkane content of <a href="/facts/Jet_fuel/4CDswF3t">jet fuels</a>.
