Abstract:
The vaporphase cracking of eugenol has been investigated in a nonisothermal, laminarflow reactor at temperatures between 300900°C and a residence time of one second. Products identified by gas chromatography were oxygenated compounds such as phenols, furans, ethers, and acids, singlering and polycyclic aromatic hydrocarbons, C1C6 hydrocarbon gases, and carbon monoxide. Temperature had a marked effect in governing the overall product composition. Conversion of eugenol to products increased above 400°C and was completed at 14 1 1 600°C. Reaction rate parameters derived from the conversion data were A = 10s and Ea = 50.7 kcal mol. The oxygenated compounds were observed as products in the range 450800°C, peaking in yields below 700°C. The aromatic hydrocarbons and light gases dominated the product composition above 600°C, especially at 900°C, the highest temperature investigated. Based on the experimental data showing the effect of temperature on product composition, reaction pathways leading to products formation are proposed.
