Benzoyl chloride (2 mL, density 1.21 g cm-3) is added in small quantities at a time, and the mixture shaken vigorously with occasional cooling under the tap or in ice water. The reaction of phenol with benzoyl chloride to give phenyl benzoate is known as : In Wolff‐Kishner reduction, the carbonyl group of aldehydes and ketones is converted into. Identify compound X in the following sequence of reactions: Identify a molecule which does not exist. If phenol is shaken with benzoyl chloride and excess amount of sodium hydroxide solution, it is benzoylated to give the ester, phenyl benzoate. In order to get a reasonably quick reaction with benzoyl chloride, the phenol is first converted into sodium phenoxide by dissolving it in sodium hydroxide solution. 2 mL of benzoyl chloride is added. https://commons.wikimedia.org/wiki/File:Phenyl_benzoate.svg, Theoretical yield is approximately 2 grams, The melting point of phenyl benzoate is 162. Determin… After 15 minutes the solid benzoate separates out: the solution should be alkaline at the end of the reaction; if not alkaline, or if oily, add a solid pellet of sodium hydroxide and shake again. Log in. Secondary School. Calculate the maximum mass of aluminium that can be produced from 1000kg aluminium oxide. 1. devendraKumar6057 is waiting for your help. The phenoxide ion reacts more rapidly with benzoyl chloride than the original phenol does, but even so you have to shake it with benzoyl chloride for about 15 minutes.
