Bakelite, the first commercially produced polymer, contains monomer units of phenol and formaldehyde. If an item made of Bakelite were broken, it could not be melted down and reformed. Is Bakelite a thermoplastic or thermosetting polymer? Can Bakelite be recycled?

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.

1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on the LC-MS printout. How much different are they? 2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit, explain what each of these is and why they are present. 3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by calculating the accurate monoisotopic mass. 4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source. 5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number). For one point of extra credit, see if you can identify this molecule as well and confirm by…

Please draw, not just describe!

can you draw each step on a piece of a paper please this is very confusing to me
