Spinning band distillation is one of the methods to separate high and close boiling mixtures. Spinning band distillation can be effective as it does not use solvent or other additive for the separation. Fractionation of Citronella, Cajeput, Patchouli essential oils has been experimentally conducted using B/R Instrument Spinning Band Distillation System Model 36-100. The crude oil was placed in the 150 mL heating pot and the temperature cut and heating rate was set. The range of temperature cut is around 230-300, 176-280, and 150-230°C for Patchouli, Citronella, and Cajeput, respectively. Running pressure was set at 10 mmHg for Patcouli oil, and 30 mmHg for citronella and cajeput oil. As expected, the heating process was stable and the solution manages to boil. It is observed that using spinning band distillation, the condensed vapor flow faster than simple vacuum fractionation and at the end product was maximize. The citronella, 1,8-cineole, and patchouli alcohol component were 88%, 67%, 44%, respectively. © Published under licence by IOP Publishing Ltd.
