How is benzilic acid prepared?
Benzilic acid can be prepared by the action of potassium hydroxide on benzil, in concentrated aqueous solution,1 in alcoholic solution2 or in ether;3 and by heating benzil in toluene with sodamide and then treating with water.
What is the boiling point of benzilic acid?
356°F (180°C)
Benzilic acid/Boiling point
What ingredients are used to make Benzylic acid?
Preparation. Benzilic acid can be prepared by a heating mixture of benzil, ethanol ,and potassium hydroxide. Another preparation, performed by Liebig in 1838, is the dimerization of benzaldehyde, to benzil, which is transformed to the product by the benzilic acid rearrangement reaction.
What type of reaction is the synthesis of benzilic acid from benzil?
benzilic acid rearrangement
The benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids using a base. This reaction receives its name from the reaction of benzil with potassium hydroxide to form benzilic acid.
What is Benzilic acid soluble in?
Benzilic acid, 2-hydroxybenzoic acid, 4-hydroxyben- zoic acid and benzoic acid are also quite soluble in diethyl ether and methyl tert-butyl ether.
What is the molecular formula of Benzilic acid?
C14H12O3

How to make benzilic acid from potassium benzilate?
Add 90 ml rectified spirit and 35 g benzil and reflux the content on a water bath till blue colour disappears (10-15 min). Pour the contents of the flask into a porcelain dish and cool in ice, collect the colorless needles of potassium benzilate. Dissolve the solid in 350 ml hot water and acidify with HCl slowly.
How to make benzil from benzoin and nitric acid?
Step 1: Preparation of Benzil from Benzoin. Heat a mixture of benzoin (20 g) and conc. nitric acid (100 ml) in a test tube on boiling water bath for about 1.5 hour until the evolution of oxides of nitrogen ceases. Then pour the contents into ice cold water (300 – 400 ml) with continuous shaking.

How is benzilic acid produced in a multistep reaction?
Benzilic acid was synthesized through a multistep reaction from the starting material of benzaldehyde and through the formations of benzoin and benzil. The first reaction produced benzoin by using the thiamine hydrochloride catalyst, followed by an oxidation reaction to produce benzil, and a rearrangement to synthesize benzilic acid.
