Reaction of Phenol with Formaldehyde to form Bakelite
Phenol reacts with formaldehyde to form a thermosetting polymer known as Bakelite. The reaction involves the following steps:
Formation of Resol
- Phenol (C6H5OH) reacts with formaldehyde (HCHO) in the presence of a basic catalyst to form a water-soluble compound called resol.
- The reaction typically takes place under heat and pressure to facilitate the formation of the polymer.
Condensation Reaction
- The resol undergoes a condensation reaction, where the hydroxyl (OH) groups of phenol and formaldehyde molecules combine to form ether linkages.
- This condensation reaction results in the formation of a three-dimensional network structure, making Bakelite a thermosetting polymer.
Characteristics of Bakelite
- Bakelite is a hard, durable, and heat-resistant material that finds applications in various industries.
- It exhibits excellent electrical insulating properties, making it suitable for use in electrical equipment and insulators.
- Bakelite is also resistant to chemicals and has good mechanical strength, making it a versatile material for different applications.
In conclusion, the reaction of phenol with formaldehyde in the presence of a catalyst leads to the formation of Bakelite, a thermosetting polymer with unique properties and applications.
