Summary: | Myrcene
can be used as a versatile starting material for a myriad product for various
applications. The drawbacks of the available myrcene separation techniques
promote the investigation of application of environmentally clean, faster, more
powerful, and cheaper methods. The combination of microwave heating system and
application of urea in hydrotropic-based distillation of myrcene-rich essential oil of Cymbopogon
Citratus was investigated in this work. A mathematical model of microwave assisted hydrotropic distillation (MAHtD)
of essential oil based on the diffusion-control assumption is also proposed and
validated. The MAHtD of C. citratus were performed by varying urea
concentrations (20-30%) and temperature (105-110°C). The essential oil
composition as well as its concentration were analyzed and determined by
applying GC-MS. Research result shows that urea is proved as a good hydrotrop
for MAHtD of myrcene–rich essential oil of C. citratus. MAHtD
performed with 25% urea at a temperature of 105°C for 10 minutes gives a high
myrcene content of up to 53.53%. The obtained myrcene–rich essential oil of C.
citratus can be investigated for its utilization in various types of
applications. Moreover, the proposed model was validated with the experimental
data of MAHtD performed at a solid-liquid ratio of 1:10, 25% urea solution, and
a temperature of 105°C. The experimental data show a good agreement with the
proposed model with SSE of 0.033. The obtained effective diffusivity of the
essential oil and the Henry constant in which essential for industrial scale-up
process are 2.245 and 0.42,, respectively. The effective diffusivity value was higher than those
obtained from hydro distillation and microwave-assisted hydro distillation of
other essential oil, which shows that urea, is a good solubilizing agent for C.
citratus essential oil. |
