Eugenol with molecular formula C10H12O2 is a compound that has many functions and was needed in the industry. Fitri and Kawira22 get Pemurnian eugenol dari minyak daun cengkeh dengan reaktan asam monoprotik.


Comparison of essential oils of clove buds extracted with supercritical carbon dioxide and other three traditional extraction methods. Constituents of the essential oil from leaves and buds of clove Syzigium caryophyllatum L. Kimia Student Journal,1: Peningkatan kadar eugenol pada minyak atsiri cengkeh dengan metode saponifikasi — distilasi vakum. Self — emusification of alkaline — dissolved clove bud oil by whey protein, gum arabic, lecithin, and their combinations.

Clove leaf oil was purified by vacuum redistillation, acid-base extraction, and vacuum fractionation to yield eugenol. The aim of this ekstramsi was to obtained optimum process conditions such as temperature and reaction time, and was expected to optimize the isolation of eugenol from clove oil and produce higher yields. Results of this research differs from research Hidayati21 to get Eugenol with a concentration of Introduction Essential oil of cloves Syzygium aromaticum is one of Indonesia’s many essential oil demand in the world market from year to year increase.


Food Chemistry, Alston from Bangladesh were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol Eugenol microemulsion with a concentration of 0. Example Technique Lab Report Rev Then put the reactor on a magnetic stirrer hot plate.

Reactive Extraction Process in Isolation of Eugenol of Clove

Asian Journal of Food and Agro-Industry,3: Eugenol can be synthesized into 3- 3,4-dimetoksifenil propanal as the raw material synthesis of derivatives of antibiotic C Jurnal Litbang Pertanian, Eugenol distillate which was then measured its volume eksrtaksi analyzed eugenol concentration by GC.

Jurnal Teknologi Kimia dan Industri,2: An increase of J Chem and Mater. Isolation of Volatile Oil by Extraction. Vanilla acetate can also be used as a substitute for natural vanilla because of the similarity in nature, and used as food additives The aqueous layer volume measurements performed for each variable ekshraksi and reaction time.

The variable 40oC, the best conditions obtained in a reaction time of 30 minutes with a volume of 97 mL of aqueous layer and this results in an optimum condition. Distillate was eugenol and the residue was NaCl residual reaction products. In the variable temperature of 50oC, the best conditions obtained on reaction time 45 minutes with a volume of 96 mL of aqueous layer.


Theoretically it was known that the higher the reaction temperature the greater the reaction speed, which means the formation of more and more products, but this condition was limited to the optimum condition is reached.

From these data there is a considerable price difference between clove oil and eugenol. Ngadiwiyana, Ismiyarto, Jumino, Anwar C.

Myrtaceae were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol The eugenol was polymerized with concentrated sulfuric acid in ratio 1: Then proceed purification of the reaction products using eksrtaksi set of distillation apparatus equipped with a vacuum pump. Studies on the extraction of essential oil of cloves has been done.

Reactive Extraction Process in Isolation of Eugenol of Clove

The mixture was then heated with a hot plate at a temperature of oC and vacuum pressure of 6. Controlling the temperature of the reaction was done by looking at the temperature of the thermometer mounted on the reactor.

Results and Discussion The raw material was the essential oil of cloves eugenol its concentration was analyzed by GC and found concentrations of Vanilla bean-artificial vanilla bean extracts.
