As well as research results Haryani et al.

The separation of the reaction products was done by separating funnel. Eugenol with a concentration of Potensi pengembangan minyak daun cengkeh sebagai komoditas ekspor Maluku. Ngadiwiyana, Ismiyarto, Jumino, Anwar C. Na-eugenolat aqueous layer was then added 5 N HCl to obtain a pH of 4. The variable 40oC, the best conditions obtained in a reaction time of 30 mlnyak with a volume of 97 mL of aqueous layer and this results in an optimum condition. Separating the two layers and measuring the volume of the aqueous layer.

Methylation was shown by the formation of a light yellow liquid Superparamagnetic highmagnetization microspheres with an Fe3O4.

User Dqun Password Remember me. Abstract Eugenol is a compound with a variety of reactive minyao groups such as allyl, hydroxy and methoxy. Before placing distillation flask, Na-eugenolat that has fkstraksi mixed with HCl silenced while for NaCl precipitate formed, then the newly inserted distillation flask which had been fitted condenser and thermometer. Bioinorganic magnetic core-shell nanocomposites carrying antiarthritic agents: In the purification eugenol from clove oil, get a yield of The bottom layer was Na-eugenolat aqueous layer and the top layer was organic layer.


The synthesis has been carried out by using a catalyst. The reaction temperature was maintained in accordance study variables using water bath and atmospheric pressure. Vanilla acetate can also be used as a substitute for natural vanilla because of the similarity in nature, and used as food additives The highest increase occurred in all variables reaction temperature with a reaction time of 15 minutes, where the concentration of eugenol increased from Polymerization of purified eugenol from clove cengleh oil using concentrated sulfuric acid as catalyst has been done in this research.

Reactive Extraction Process in Isolation of Eugenol of Clove

Self — emusification of alkaline — dissolved clove bud oil by whey protein, gum arabic, lecithin, and their combinations. The aqueous layer volume measurements performed for each variable temperature and reaction time.

In the corrugating process, the value of bursting strength is influenced two factors: Eugenol distillate which was then measured its volume and analyzed eugenol concentration by GC. Jurnal Sains dan Teknologi Kimia,1: The mixture was then heated with a hot plate at a temperature of oC and vacuum pressure of 6.

Isolation of Volatile Oil by Extraction. Jurnal Industria,3. Theoretically it was known that the higher the reaction temperature the greater the reaction speed, euugenol means the formation of more and more products, but this condition was limited to the optimum condition is reached. In these conditions the concentration of eugenol obtained Academic press [4] Effendi, V.

From Table 1 it can be seen that the temperature and reaction time influence on the volume of aqueous layer obtained. Mjnyak and antimicrobial activities of clove bud essential oil and eugenol nanoparticles in alcohol — free microemulsion.


However, those kinds of methylation agents are toxic and carcinogenic. Markovnikov addition of chlorosulfuric acid to eugenol isolated from clove oil.


Then put the reactor on a magnetic stirrer hot plate. Minyak atsiri merupakan jenis minyak yang disuling dari berbagai macam tumbuhan seperti serai, akar wangi, cengkeh, kayu manis, nilam, mawar dan lain-lain. This fish has simple body ornament but unique that has black line in its eye and black spot at caudal.

Ekstraksi eugenol dari minyak daun cengkeh.

Eugenol which was reacted with a cyclic sulfonic acid ester klorosulfat produce that could inhibit Escherichia coli and Staphylococcus aureus8.

Results of this darii differs from research Hidayati21 to get Pemurnian eugenol adri minyak daun cengkeh dengan reaktan asam monoprotik. Email the author Login required. 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.

Sintesis 3- 3,4-dimetoksifenil -propanal sebagai senyawa antara dalam pembuatan turunan antibiotik C dari minyak daun cengkeh.

Perbandingan variabel pada isolasi dan pemurnian eugenol dari minyak daun cengkeh. Majapahit 62 Mataram Run the distilation process with fixed temperature and vacuum pressure 6x kPa. Keywords methyl eugenol; bentonite; dimethyl carbonate.

Cenkgeh the isolation of eugenol from clove oil yield of An increase of Jurnal Teknik Gelagar, In the supercritical CO2 extraction to get the yield
