Chapter 24, Problem 24.1QP
Bakelite, the first commercially produced
Expert Solution & Answer
Interpretation Introduction
Interpretation: Bakelite, a thermoplastic or thermosetting plastic has to explained. Bakelite can be recycled or not has to be explained.
Concept Introduction:
- Thermoplastics are polymers which gets melted on heating and can be reshaped. These are formed by addition polymerisation reaction and are linear in structure.
- They are recyclable and reshaped.
- Examples are Polystyrene, Polyethylene, PVC, Teflon, etc.
- Thermosetting plastics are polymers which become hard and infusible solid on heating. These are formed by condensation polymerisation reaction and possess three dimensional cross linked structures.
- They are not recyclable and reshaped.
- Examples are Melamine formaldehyde resin, bakelite etc.
To Explain: whether bakelite is a thermoplastic or thermosetting plastic also explain whether bakelite can be recycled or not.
Answer to Problem 24.1QP
Answer
- Bakelite is a thermosetting plastic
- No, bakelite cannot be recycled.
Explanation of Solution
Bakelite is a polymer which is formed by the condenstion of monomer units of formaldehyde and phenol. It is also called as phenol formaldehyde resin. It a thermosetting plastic with three dimensional cross linked structure. It cannot be reshaped or recycled.
Bakelite is a thermosetting plastic and hence, it cannot be recycled.
Conclusion
Bakelite, a thermoplastic or thermosetting plastic and bakelite can be recycled or not were explained.
