How do you convert phenol to salicylic acid give equation?

Phenol is converted to salicylic acid by Reimer-Tiemann reaction. In this reaction, ortho hydroxyl benzaldehyde and ortho hydroxyl benzoic acid are obtained.

What reaction converts phenol to salicylic acid?

Kolbe-Schmitt reaction (Kolbe process): A reaction for adding a carboxyl group onto the benzene ring of a phenol. Used for the industrial synthesis of salicylic acid to be converted into aspirin. In this example of the Kolbe-Schmitt reaction, phenol is converted into salicylic acid.

How do you make phenol from salicylic acid?

The industrial preparation of salicylic acid is carried out by Kolbe-Schmitt reacion : sodium phenoxide and carbon dioxide are heated at 120-140∘C under a pressure of several atmoshpheres.

How will you convert phenol to salicylic acid name the reaction and give its mechanism?

Phenol to salicyaldehyde: When phenol is treated with chloroform in an aqueous sodium hydroxide solution followed by hydrolysis with acid, salicylaldehyde is formed. If the solvent chloroform (CHCl3) is replaced by carbon tetrachloride (CCl4), salicylic acid is formed.

How is phenol converted into salicylaldehyde?

When the phenol is heated with chloroform followed by an alkali solution, then the phenol is converted into salicylaldehyde.

How is phenol converted to salicylaldehyde name the reaction?

Salicylaldehyde is prepared by heating phenol and chloroform together in the presence of potassium hydroxide and sodium hydroxide. This reaction is called the Relmer-Tiemann reaction. The correct option is Option C, Reimer-Tiemann reaction.

Is salicylic acid a phenol?

Salicylic acid contains a phenol group, and phenols are known to be irritating. Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst. The phenol group on the salicylic acid forms an ester with the carboxyl group on the acetic acid.

What is Reimer-Tiemann reaction Class 12?

When phenol reacts with chloroform in the presence of bases (NaOH/KOH), an aldehyde (−CHO) group gets introduced in the ring at a position ortho to the phenolic group and salicylaldehyde is formed. This reaction is called the Reimer-Tiemann reaction.

What is Reimer-Tiemann reaction give equation?

(i) Reimer-Tiemann reaction → When phenol is treated with chloroform in the presence of sodium hydroxide, a −CHO group is introduced at the ortho position of the benzene ring. This reaction is known as the Reimer-Tiemann reaction. The intermediate is hydrolyzed in presence of alkalis to produce salicylaldehyde.

What is the chemical formula for salicylic acid?

C₇H₆O₃
Salicylic acid/Formula

Salicylic Acid (from Latin salix, willow tree) is a lipophilic monohydroxybenzoic acid, a type of phenolic acid, and a beta hydroxy acid (BHA). It has the formula C7H6O3.

How is salicylic acid converted to aspirin give equation?

For the preparation of aspirin, salicylic acid is reacted with an excess of acetic anhydride. Small amount of strong acid is used as a catalyst in these reactions which enhances the speed of reaction acid used is phosphoric acid. Excess acetic acid will be extinguished with the addition of water.

What is Reimer reaction?

The Reimer–Tiemann reaction is a chemical reaction used for the ortho-formylation of phenols; with the simplest example being the conversion of phenol to salicylaldehyde. The reaction was discovered by Karl Reimer and Ferdinand Tiemann.
