Questions & Answers

Q: How was Bakelite, a key historic plastic, synthesized?

Bakelite, invented by Baekeland, is made from phenol and formaldehyde with added wood flour for strength, reacting with hydrochloric acid to form a tough resin material.

Q: What unique properties did Bakelite possess that made it popular in the past?

Bakelite's brittleness but moldability when heated allowed for the creation of various objects like telephones, radios, and knobs due to its durability and insulation properties.

Q: Why is Bakelite not as commonly used today?

Despite its historical significance, Bakelite has been largely replaced by more advanced plastics. However, collectors cherish Bakelite objects for their nostalgic value and unique characteristics.

Q: How did the chemical reaction between phenol and formaldehyde lead to the formation of Bakelite?

The reaction between phenol and formaldehyde, catalyzed by hydrochloric acid, forms a network of phenol molecules with CH2 groups, creating the polymer known as Bakelite.

Summary & Key Takeaways

• Bakelite, a pioneering plastic, was invented by Baekeland a century ago, popularly used in telephones and radios.

• The synthesis of Bakelite involves a reaction between phenol, formaldehyde, and wood flour for added strength.

• The chemical process includes combining phenol and formaldehyde with hydrochloric acid to create a tough resin material.
