Chemical composition and antimicrobial of the essential oil of Eugenia caryophyllata Cloves extracted by conventional and microwave techniques. Example Technique Lab Report. In the purification eugenol from clove oil, get a yield of Although Indonesia is the largest clove oil exporter in the world, but the fulfillment of eugenol Indonesia still have to import from other eugnol. Markovnikov addition of chlorosulfuric acid to eugenol isolated from clove oil.

Reactive Extraction Process in Isolation of Eugenol of Clove

Then proceed purification of the reaction products using a set of distillation apparatus equipped with a vacuum pump. The separation of the reaction products was done by separating funnel. Distillate was eugenol and the residue was residual NaCl reaction products. Yield of eugenol obtained from the results of this study were relatively better when compared to previous studies. Then put the reactor on a magnetic stirrer hot plate.


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. The reaction between eugenol and NaOH was a fast reaction reaches equilibrium. Research Haryani et al.

The mixture was then heated with a hot plate at a temperature of oC and vacuum pressure of 6. 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. Perbandingan variabel pada isolasi dan pemurnian eugenol dari minyak daun cengkeh.

Studies on the extraction of essential oil of cloves has been done.

In the study of isolation eugenol from clove oil, there is eugeonl data on the reaction temperature used and reaction time used is relatively long. From these data there is a considerable price difference between clove oil and eugenol.

Antioxidant and antimicrobial activities of clove bud essential oil and eugenol nanoparticles in alcohol — free microemulsion. Research stage begins by inserting a ml clove essential oil and 0. In the isolation of eugenol from clove oil yield of Antimicrobial effects of coating solution containing clove oil and hydrophobic starch for coating paper board. Eugenol microemulsion with a concentration of 0.


An increase of Example Technique Lab Report Rev Conclusions The optimum conditions of temperature extraction reactive process that was 40oC, reaction time of 30 minutes, 0. From Figure 2 shows that the temperature and reaction time affect yield eugenol obtained.

On the extraction of essential oil of cloves with Eugenia caryophyllata hidrodestilasi method for minutes get a yield of 5. Kajian jenis dan konsentrasi asam. Oksidasi eugenol asetat dan uji aktivitas antioksidan senyawa turunannya. Constituents ekstraki the essential oil from leaves and buds of clove Syzigium caryophyllatum L.


Polyeugenol from eugenol of clove leaf oil resulted from redistillation, extraction, and fractionation is in solid form yield: Yield of eugenol was calculated using the following equation: Research on the isolation of eugenol from clove oil also has been done. Isolation of Volatile Oil by Extraction. Before placing distillation flask, Na-eugenolat that has been mixed with HCl silenced while for NaCl precipitate formed, then the newly eksteaksi distillation flask which had been fitted condenser and thermometer.
