The purpose of this study was to obtained optimum conditions a reactive extraction process in isolation eugenol from clove essential oil associated with the temperature and time process. Research stage begins by inserting a ml clove essential oil and 0. After a reaction time achieved according to the study variables 15, 30, 45, 60 and 75 minutes the reaction product was then separated.
The bottom layer was Na-eugenolat aqueous layer and the top layer was organic layer. Na-eugenolat aqueous layer was then added 5 N HCl to obtain a pH of 4. Before placing distillation flask, Na-eugenolat that has been mixed with HCl silenced while for NaCl precipitate formed, then the newly inserted distillation flask which had been fitted condenser and thermometer. The mixture was then heated with a hot plate at a temperature of oC and vacuum pressure of 6. Distillate was eugenol and the residue was NaCl residual reaction products.
Eugenol distillate which was then measured its volume and analyzed eugenol concentration by GC.
The optimum process conditions obtained in the reactive extraction temperature of 40 oC, reaction time of 30 minutes at a concentration of eugenol of Introduction Essential oil of cloves Syzygium aromaticum is one of Indonesia’s many essential oil demand in the world market from year dsun year increase. Clove essential oil was produced from the leaves, flowers and stems plant cloves with the extraction process.
From these data there is a considerable price difference between clove oil and eugenol. Although Indonesia is the largest clove oil exporter in the world, but the fulfillment of eugenol Indonesia still have to import from other countries2. Eugenol is the main component in the essential oil of clove. Clove essential oil Syzigium aromaticum L. Myrtaceae were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol Essential oil of clove leaf Syzigium caryophyllatum L.
Alston ekstraksu Bangladesh were isolated by hidrodestilasi process, from the analysis of GC-MS has the composition of eugenol Eugenol with molecular formula C10H12O2 is a compound that has many functions and was needed in the industry. Eugenol serves as an analgesic, anti-inflammatory, antimicrobial, antiviral, antifungal, antiseptic, antispasmodic, antiemetic, a stimulant and a local anesthetic that was widely used in the pharmaceutical world5,6.
Eugenol microemulsion with a concentration of 0. Eugenol microemulsion with a concentration of Eugenol which was reacted with a cyclic sulfonic acid ester klorosulfat produce that could inhibit Escherichia coli and Staphylococcus aureus8. Eugenol can be synthesized into 3- 3,4-dimetoksifenil propanal as the raw material synthesis of derivatives of antibiotic C Vanilla acetate can also be used as a substitute for natural vanilla because of the similarity in nature, and used as food additives Vanilla acetate can be made from the oxidation reaction of isoeugenol acetate with KMnO4 with microwave heating A mixture of cloves eugenol from 1.
Compound eugenol contained in the commercial formulation has a level of stability which varies depending on the concentration. Eugenol with a concentration of Clove bud oil emulsion CBO in alkaline solution with the addition of whey protein emulsifier, gum arabic, lecithin or a mixture of all of them is stable for 7 days of storage Studies on the extraction of essential oil of dan has been done.
In the supercritical CO2 extraction to get the yield Extraction of essential oils clove buds by steam distillation process for hours at a yield of On the extraction of essential oil of cloves with Eugenia caryophyllata hidrodestilasi method for minutes get a yield of 5. Research on the isolation of eugenol from clove oil also has been done.
In the isolation of eugenol from clove oil yield of In the purification eugenol from clove oil, get a yield of In the study of isolation eugenol from clove oil, there is no data on the reaction temperature used and reaction time used is relatively long. The aim of this study 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.
The reaction temperature was maintained in accordance study variables using water bath and atmospheric pressure. The separation of the reaction products was done by separating funnel. Then proceed purification of the reaction products using a rkstraksi of distillation apparatus equipped with a vacuum pump. Assembling the reactor as a reaction consisting of a three-neck flask and condenser and to strengthen its position with the buffer and the stand.
Then put the reactor on dauj magnetic stirrer hot plate. Completing the reactor with a thermometer to control the daum temperature. Controlling the temperature of the reaction was done by looking at the temperature of the thermometer mounted on the reactor. After a reaction time achieved according to the study variables mihyak, 30, 45, 60 and 75 minutes the reaction product was then inserted separating funnel and allowed to stand for 24 hours to form two layers.
Reactive Extraction Process in Isolation of Eugenol of Clove
Separating the two layers and measuring the volume of the aqueous layer. Before placing Na-eugenolat distillation flask that has been mixed with HCl silenced while for NaCl precipitate formed, then the newly inserted distillation flask which had been fitted behind the cooler and thermometer.
Distillate was ekstrakksi and the residue was residual NaCl reaction products. Results and Dark The raw material was the essential oil of cloves eugenol its concentration was analyzed by GC and found concentrations of Yield of eugenol was calculated using the following equation: The aqueous layer volume measurements performed for each variable temperature and reaction time. From Table 1 it can be seen that the temperature and reaction time influence on the volume of aqueous layer obtained.
The higher the temperature and reaction time, the greater the volume of aqueous layer to obtain optimum conditions. Volume aqueous layer Na-eugenolat at various temperatures and reaction ekstrasi Temperature oC 30 40 50 Time of Reaction mnt 15 30 45 60 75 15 30 45 60 75 15 30 45 60 75 Volume aqueous layer mL 86 87 89 90 91 96 97 91 89 89 88 93 96 89 87 The best conditions of each of eksteaksi different variables- At 30oC temperature variables, the best conditions obtained in a reaction time of 75 minutes with a volume of 91 mL of aqueous layer.
In the variable temperature of 50oC, the best conditions obtained on reaction time 45 minutes with a volume of 96 mL of aqueous layer. 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. Theoretically it was known that the higher the reaction temperature the greater the reaction speed, which means the formation emstraksi more and more products, but this condition was limited to the optimum condition is reached.

NaOH function in this process there are two, namely as a cenbkeh in the extraction process that removes eugenol from kariofilin phase to the aqueous phase. Subsequently NaOH serves as a reactant that will react with eugenol. From Figure 2 shows that the temperature and reaction time effect on the increase in the minyzk concentration of eugenol obtained.
The highest increase occurred in all variables reaction temperature with a reaction time of 15 minutes, where the concentration of eugenol increased from After a reaction time of 15 minutes were relatively small increase in the concentration of eugenol and almost evenly on cengekh the variables of temperature and reaction time.
The reaction between eugenol and NaOH was a fast reaction reaches equilibrium. An increase of This result was better than the results Lutfi et al. As well as research results Haryani et al.
From Figure 2 shows that the temperature and reaction time affect yield eugenol obtained. Visible optimum conditions were different in each study variable. At a reaction temperature of 30oC variable has not been achieved the optimum conditions because the yield eugenol eugenpl increase with the highest yield at the reaction time of 75 minutes was Yield of eugenol obtained from the results of this study were relatively better when compared to previous studies.
Fitri and Kawira22 get Research Haryani et al.
Results of this research differs from research Hidayati21 to get Conclusions The optimum conditions of temperature extraction reactive process that was 40oC, reaction time of 30 minutes, 0.
In these conditions the concentration of eugenol obtained Potensi pengembangan minyak daun cengkeh sebagai komoditas ekspor Maluku.
