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 placed into a 50ml bottomed flaskful. The categorisation was underwent wane for 1 hr at nearly 120oC. The commixture was cooled to the inhabit temperature. 10ml of distilled water was added into the flask to displace the solid. The mixture was transferred to a separating funnel. The flask was rinsed by 15ml of dichloromethane (DCM). just about add up of anhydrous magnesium sulfate was added into the cone-shaped flask 3 with mixture. A dry 25ml round-bottom flask was weighted. Mixture from conical flask 3 was transferred to the round-bottomed flask by filtration. The mixture was underwent circuit evaporation to remove DCM and the balance was terminal exam reaping. The unit of measuring round-bottomed flask with final ware was weighted. Results mess sign of round-bottomed flask: 30.64g commode of round-bottomed flask with final product: 32.27g Mass of product: 1.63g Density of 1-bromobutane: 1.27g/ml Volume of alcoholic drink utilise: 2ml MW of 1-bromobutane is 137g groyne-1 so that, the inguen 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 gram molecule 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 pattern transfer catalyst Aliquat 336 from the mixture, starting line water and dichloromethane (DCM) was employ to dissolve catalyst into aqueous phage. imputable to catalyst in hard to dissolve by its own, DCM is historic for dissolving it. By removing the aqueous layer, catalyst would be withdraw at the identical time. In further remotion of aqueous layer, such as by dehydrating agent, catalyst foundation be mostly...If you want to protrude a full essay, roll it on our website: Ordercustompaper.com
