Synthesis Of Butyl Benzoate

Procedure 2.0ml of 1-bromobutane, 2.97g of sodium benzoate, 5.0ml of body of water and 4 drops of Aliquat 336 were fixed into a 50ml bottomed flaskfulfulful. The categorisation was underwent reflux for 1 hr at nearly 120oC. The commixture was cooled to the room temperature. 10ml of distilled water was added into the flask to force out the solid. The mixture was transferred to a separating funnel. The flask was rinsed by 15ml of dichloromethane (DCM). Some add up of anhydrous magnesium sulfate was added into the conical flask 3 with mixture. A dry 25ml round-bottomed flask was weighted. Mixture from conical flask 3 was transferred to the round-bottomed flask by filtration. The mixture was underwent rotary evaporation to pip DCM and the rest was final reaping. The unit of measurement round-bottomed flask with final product was weighted. Results mess hall of round-bottomed flask: 30.64g potful of round-bottomed flask with final product: 32.27g Mass of product: 1.63g Density of 1-bromobutane: 1.27g/ml Volume of alcohol hire: 2ml MW of 1-bromobutane is 137gbulwark-1 so that, the mole of 1-butanol: (2mlx 1.27g/ml) / 137gmol-1 = 0.01854mol Since the no. of mol of 1-bromobutaneto butyl benzoateis 1:1 So that, theoretically, usage of0.01854 mol of 1-bromobutanewould obtain 0.01854 mol of butyl benzoate.

In the experiment, Mass of butyl benzoate: 1.63g Density of butyl benzoate: 1.00g/ml MW of butyl benzoateis 178 gmol-1 the mole of butyl benzoate: 1.63g / 178 gmol-1 = 0.0091573mol Yield of butyl benzoatesynthesized= (0.0091573 mol / 0.01854 mol) x c% = 49.39% Questions 1.To remove phase transfer throttle Aliquat 336 from the mixture, first water and dichloromethane (DC! M) was used to dissolve gas into sedimentary phage. imputable to atom smasher in hard to dissolve by its own, DCM is historic for dissolving it. By removing the aqueous layer, gas would be withdraw at the same time. In however removal of aqueous layer, such as by dehydrating agent, catalyst can be mostly...If you want to get a amply essay, order it on our website: OrderEssay.net
