Principle : Here alcohol group of benzoin is oxidized to ketone group forming benzil in the presence of concentrated nitric acid. Nitration of aromatic ring is not occurring as sulphuric acid is totally absent in the whole process.


Aim : To prepare benzil from benzoin. Reaction :. Mechanism :. Use : It is used in the manufacture of glycollate pharmaceuticals including benzillic acid, clidinium, dilantin, and flutropium. HNO 3. Ethanol etc. Glass rod. Buchner funnel etc. The content is poured into — ml ice cold water with shaking. Then the product is filtered with suction and washed with cold water. It is recrystallized from ethanol, taking 2.

Calculation :. Here limiting reagent is benzion; hence yield should be calculated from its amount. Theoretical yield :. Therefore, 20 g benzion will form …….?

X g benzil. Benzil was synthesized and the percentage yield was found to be Nitration on salicylic acid occurs by placing a nitro group on the aromatic ring system via an electrophilic aromatic Esters are hydrolysed either by an acid or a base. Alkaline hydrolysis of ester is irreversible which is also Spaonification value is defined as the number of milligrams of KOH required to completely hydrolyse saponify one gram of Alkaline hydrolysis of esters is called saponification and is an irreversible process.The active ingredient is Benzyl Nicotinate niacinamidepart of the drug group of vasodilators that widen blood vessels.

The first of these is benzyl chloride, the second benzal chloride, and the third benzotrichloride or phenyl chloroform. It is then only necessary to brominate the benzyl cyanide by treating it with bromine vapor.

Benzyl benzoate has been used recently to reduce the high blood pressure of hypertension. This chloride is then mixed with sodium cyanide in alcoholic solution and distilled, benzyl cyanide being the result. Take this quiz on the Words of the Day from April 6—12 to find out!
