Formation of Bakelite:
Bakelite is formed from the reaction of formaldehyde with phenol. This process involves the following steps:
Step 1: Formation of Novolac:
- Phenol reacts with formaldehyde in the presence of an acidic or basic catalyst to form novolac, which is a low-molecular-weight compound.
Step 2: Formation of Bakelite:
- The novolac is then heated in the presence of more formaldehyde and a basic catalyst. This leads to further polymerization and cross-linking, resulting in the formation of Bakelite.
Key Points:
- Bakelite is a type of synthetic resin that was one of the first plastics to be produced.
- It is known for its high heat resistance, electrical insulating properties, and durability.
- Bakelite was widely used in electrical insulators, radio and telephone casings, and various other products in the early 20th century.
- The reaction of formaldehyde with phenol to form Bakelite is an example of a condensation polymerization reaction.
In conclusion, Bakelite is formed from the reaction of formaldehyde with phenol, which undergoes polymerization and cross-linking to produce the final product.
