Triethylamine as an initiator for cracking of heptane

Triethylamine was found to be effective in promoting the cracking of heptane at the temperature of 550–650 °C. The experimental yields of ethylene and propylene are more than twice as high as the calculated values on hypothesis of no interaction between triethylamine and heptane, when the mass fract...

More Information
Summary:Triethylamine was found to be effective in promoting the cracking of heptane at the temperature of 550–650 °C. The experimental yields of ethylene and propylene are more than twice as high as the calculated values on hypothesis of no interaction between triethylamine and heptane, when the mass fraction reaches 6% at the most notable temperature of 550 °C. The accelerating mechanism is studied by gas chromatography–mass spectrometry (GC–MS) and it shows that the accelerating effect is mainly attributed to the initiative release of CH 3CH 2 from triethylamine by the scission of the C–N bond.
