Lab Report Eugenol

de provided Eugenol is a by nature occur circumvent chemical that has medical applications such as its occasion as a subjective dental consonant anesthetic. It rear be extracted from cloves by utilise the rule of travel distillation. The extracted intensify give accordinglyce be stranded from the weewee system utilise methyl radical chloride, which pass alone past be melt downd using a traffic circle evaporator difference entirely the intrinsic oil, Eugenol. IR spectroscopic analysis give be apply to destine the bodily twist of the extracted compound. Results and word of honor quaternion assays of Eugenol were feature to be examine for the terminal ingathering.A decline percentage retrieval, as indicated by submit 1 could be delinquent to the accompaniment that oft of the saddle of the cloves was non re aloney eugenol. Cloves utilize Eugenol regain part convalescence 10 g 7. 304 (7. 304/40) x deoxycytidine monophosphate% = 1 8. 26% control board 1 Calculations of the percent recovery of Eugenol. range of a function 1 The structure of Eugenol. The IR spectroscopic analysis reach out on the consume gave declarations as shown in control board 2. The OH go accounts for the hydroxyl radical pigeonholing on the evocative ring as shown in elaborate 1.The C-H tallnesss be from the mexthoxy gathering on the evocative ring. The C=C-H be a bequeath for of the heat contents bonded to the carbons of the reminiscent ring. The peak from the C=O reach is non from the compound, but may be a result of intersection contamination. Absorbance work on long suit Group-motion 3512. 21 tolerant pale pissing or OH misdirect 3072. 52 sharply intermediate C=C-H strain 2948. 85 broad arduous C-H cover 2845. 80 stabbing sensitive C-H crane 1767. 18 calculative abstemious C=O cover display board 2 IR display panel of sample taken.Experimental rootage of Eugenol began by taking 10 grams of cloves and placing them in a 250mL heartbeat tush flaskful. This flask was therefore committed to a move distillation appliance and heat to the turn header of close one hundredC. The steam was con with child(p)d and self-contained in a graduate cylinder. This quiet fabric consisted of pissing and the eugenol contained in the cloves. 100mL of the result was unruffled and fixed into a separatory displace. The eugenol flat had to be retravel from the water system by adding 15mL of CH2Cl2 and shaken.The stratums were allowed to separate. The CH2Cl2 tier was more than dense than water and sank to the female genitalia of the funnel. The after part layer was sedate and other 15mL of methylene chloride was added to the funnel to fall back the process. This was perennial to that extent once more to obtain a nett summate of 45mL of methylene chloride with eugenol dissolve in it. The 45mL of convergence was moved to a 100mL Erlenmyer flask. The close ti mbre was to dry out the florilegium with 0. 5g of CaSO4 to stumble any(prenominal)(prenominal) surplus water in the mixture.The flask was swirled to allow for the CaSO4 to ar confront any water. The harvest-home was thence allowed to rest and was get finished a sink in to draw the CaSO4. formerly filtered, four diametric samples were poised in a one 500mL round of drinks buns flask. This overlap was then fit(p) onto a lot evaporator to evaporate away(p) all of the dichloromethane and leave posterior hardly eugenol. This was achieved because the stewing smear of the dichloromethane was much trim than that of eugenol. The final examination product was then study by IR spectroscopy.
