The aim of this work was to assess the performance of a vacuum fractionation column length for fractions composition of major components of citronella essential oil. This study used column lengths of 1 m and 2 m. The column packing raschig ring-shaped cylinder with height 1.8 cm and diameter 1.5 cm. The column is filled as much as 75% of the length of the column. Fractions from column top, middle and residue were analyzed by gas chromatography-mass spectrometry (GC/MS). The major components of citronella oil were citronellal (31.63%), citronellol (17.62%) and geraniol (10.92%). The use of 2 m packaging column length in batch vacuum fractionation distillation produced highest citronella content was (88.43%) on top fraction. The highest citronellol content were (24.48%) and (32.17%) in the middle fractions column for 1 m and 2 m column lengths respectively, while the highest geraniol was 58.26% and 37.76% in the middle and residue fraction for 2 m column length, respectively. © 2019 Published under licence by IOP Publishing Ltd.
