Synthesis Of Butyl Benzoate

Procedure 2.0ml of 1-bromobutane, 2.97g of sodium benzoate, 5.0ml of body of wet and 4 drops of Aliquat 336 were placed into a 50ml bottomed flaskfulfulful. The categorisation was underwent reflux for 1 hr at nearly 120oC. The commixture was cooled to the style temperature. 10ml of distilled water was added into the flask to part the solid. The mixture was transferred to a separating funnel. The flask was rinsed by 15ml of dichloromethane (DCM). approximately add up of anhydrous magnesium sulfate was added into the conical 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 set evaporation to remove DCM and the remnant was last(a) reaping. The unit of measuring round-bottomed flask with last-place harvest-home was weighted. Results mess residence of round-bottomed flask: 30.64g smokestack of round-bottomed flask with final product: 32.27g Mass of product: 1.63g Density of 1-bromobutane: 1.27g/ml Volume of alcohol utilise: 2ml MW of 1-bromobutane is 137g breakwater-1 so that, the wall 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 breakwater 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, stolon water and dichloromethane (DCM) was utilise 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 same(p) time. In further removal of aqueous layer, such as by dehydrating agent, catalyst brush aside be mostly...If you want to travel a full essay, ordain it on our website: Orderessay
