the home while allowing people to keep their doors open. After considering numerous ideas I concluded that the best way to do this is via a eugenol based fly spray. Due to tests done by Dr Sinthusiri we have evidence that suggests house-flies will move away from areas that have eugenol sprayed into them. To make it non-harmful and easy to install‚ the eugenol will be dispersed in automatic canisters set to

These data are consistent with the structure of eugenol‚ shown in Figure 2 below: In addition‚ the IR of the product from the steam distillation of cloves closely corresponds with that of an authentic sample of eugenol shown in the lab text.9 Therefore‚ it can be concluded that the oil which was isolated from cloves is in fact‚ eugenol. 0.53 g of eugenol was recovered from 5 g of cloves. This corresponds to a percent recovery of 7.46%: Amt. Eugenol isolated 0.53 g % Recovery = ------------------------------

orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol‚ 20 mL of dichloromethane solution of clove oil was extracted twice; each time with a 15 mL portion of 3M NaOH. The aqueous extracts were then combined and acidified with approximately 17.6 mL of 6M aqueous HCl. Eugenol was isolated from the aqueous mixture by two extractions of 10 mL portions of dichloromethane. The dichloromethane extracts

cloves. Introduction By performing steam distillation we can isolate eugenol at lower temperature than its usual boiling point of 248 degree Celsius. Eugenol belongs to a category called essential oil. Many of these compounds are used as flavoring and perfumes and in the past were considered the essence of plant from which they were derived. Structure of eugenol (clove oil) and eugenol acetate: Reagents: Eugenol‚ CH2Cl2‚ Br2‚ FeCl3‚ Methanol Procedure: Co-distillation We first

simple organic chemistry experiment is described that investigates the kinetics of the reaction between 1-bromobutane (BuBr) and iodide (I−) as followed by observing the disappearance of BuBr and the appearance of 1-iodobutane (BuI) using 1H NMR spectroscopy. In small groups of three to four‚ students acquire data to examine the concentrationdependence of both the organic substrate and the nucleophile under pseudofirst-order and second-order conditions.

Objective: In steam distillation lab (lab 3)‚ we must obtain pure Eugenol from cloves through the process of steam distillation. In the crystallization lab (lab 4) part 1‚ we must acquire the best possible pure crystallization of acetylsalicylic acid from aspirin and in part 2 we must obtain a similar pure crystallization of benzil from an impure mixture of benzil. Materials: In lab 3‚ we used 75 g of cloves from which we must extract Eugenol. Water was largely used as a solvent. A polar solvent used

the aromatic hydroxyl compound‚ eugenol from crushed cloves using steam distillation. After conducting the distillation‚ the expected two layers were not visible in the centrifuge tube. Subsequently‚ the extraction and evaporation did not produce the expected oil. This result is probably due to the collection of only water vapor during distillation. From another group’s data‚ 3.80% of the oil was recovered from the cloves in which the major component is eugenol. The IR spectrum obtained is consistent
