The major product obtained on interaction of phenol with sodium hydroxide and carbon dioxide is :

When phenol interacts with sodium hydroxide and carbon dioxide, the primary product formed is sodium phenoxide, which can further react to produce sodium salicylate under certain conditions. Let’s break down this reaction step by step to understand how this occurs.

Understanding the Reaction Components

To grasp the reaction, we need to consider the three main components involved:

• Phenol (C6H5OH): A simple aromatic compound with a hydroxyl group (-OH) attached to a benzene ring.
• Sodium Hydroxide (NaOH): A strong base that can deprotonate phenol, making it more reactive.
• Carbon Dioxide (CO2): A gas that can react with the phenoxide ion formed from phenol and sodium hydroxide.

The Reaction Process

Initially, when phenol is treated with sodium hydroxide, the hydroxide ion (OH-) from NaOH deprotonates the hydroxyl group of phenol. This results in the formation of sodium phenoxide:

C6H5OH + NaOH → C6H5O⁻Na⁺ + H2O

Here, sodium phenoxide is formed, which is a salt where the phenol has lost its hydrogen ion and is now negatively charged.

Interaction with Carbon Dioxide

Next, when sodium phenoxide is exposed to carbon dioxide, it can undergo a reaction known as carboxylation. This process typically occurs under pressure or elevated temperatures. The carbon dioxide reacts with the phenoxide ion to form sodium salicylate:

C6H5O⁻Na⁺ + CO2 → C6H4(OH)(COO⁻Na⁺)

In this reaction, the carbon dioxide adds to the phenoxide, resulting in the formation of a carboxylate group (-COO⁻) attached to the aromatic ring, yielding sodium salicylate.

Summary of the Reaction Products

In summary, the major product obtained from the interaction of phenol with sodium hydroxide and carbon dioxide is sodium salicylate. This compound is significant in various applications, including its use as a precursor in the synthesis of aspirin and other pharmaceuticals.

Real-World Applications

Sodium salicylate is not just a theoretical product; it has practical implications in medicine and industry. For instance, it can be used as an anti-inflammatory agent and is involved in the synthesis of various organic compounds.
