Pemisahan Fraksi Kaya Sitronelal, Sitronelol, dan Geraniol Minyak Sereh Wangi Menggunakan Distilasi Fraksinasi Vakum

Abstract

The main compounds of citronella oil are citronellal, citronellol, and geraniol, all of which determine the fragrance intensity and price of the citronella oil it self. Separation of those compounds increased the value of citronella oil. The aim of this research is to obtain the optimum amounts of citronellal, citronellol, and geraniol fractions by vacuum of fractional distillation technology. Conditioning process using 30:1 reflux ratio obtioned purer citronellal, citronellol, and geraniol than conditioning process with 10:1 reflux ratio. The separation process was held in 5 - 4 mBar vacuum pressure and the variation of reflux ratio 10:10, 20:10, 30:10. The optimum amounts of citronellal, citronellol, and geraniol was obtioned in the variation of reflux ratio 10:10, they are 90.670 % of 620 ml, 41.101 % of 160 ml, and 53.581 % of 500 ml respectively
