Eugenol Research Paper

At high sustained temperatures, natural aromatic compounds can easily be decomposed after being evaporated. Thus, eugenol can be easily decomposed at atmospheric boiling point. In order to prevent this from occurring, the boiling point of the compound should be lowered. In steam distillation process, the boiling point are lowered by the addition of water in an partially vacuumed container, through Raoult’s Law. Eugenol and water has different vapor pressure. Water has a vapor pressure of 760 mmHg while Eugenol has a vapor pressure of 4 mmHg. Thus, the total vapor pressure in the closed system is 764 mmHg, resulting in lower boiling point. Using the Clausius-Clapeyron equation(ln (P1 / P2) = (ΔH / R) (1/T2 - 1/T1)), the boiling point of the
