Phew yeh it is a raw material.
Should of thought of cellulose aswell damn..
Hopefully at least 5/6.
I spoke about initiation propogation and termination and LDPE use of peroxide catalyst under High Temperatures and High Pressure. Actually spoke about HDPE aswell.. wasnt sure which one..
1. Fractional distillation of petroleum
2. Cracking of a hydrocarbon to form ethene (equation)
3. Photosynthesis to produce glucose (equation)
4. Fermentation of glucose for ethanol (equation)
5. Dehydration of ethanol to form ethene (equation)
6. Polymerisation to form high density polyethene using Zeiger catalyst
7. Equation for polymerisation of ethene and diagram of HDPE with explanation of properties to explain why it is useful as a bottle
I loved this question. Absolutely loved it. And all of this fit into the space provided.
I used ethene from crude oil, because crude oil is a natural raw resource. Cellulose is correct but i think some people may have taken natural as to mean renewable as well, which cellulose is, but im pretty sure it just meant a material that is not synthetic, and crude oil isnt.
Talked about ethene from fractional distillation and catalytic cracking giving equations. Talked about polymerisation using Zeiger process to form HDPE. Pretty sure HDPE is acceptable because LDPE is used to make cling wrap but it probably can be easily used to make drink bottles like pump bottles, but you can buy hard plastic bottles that would be made from HDPE, so both are probably correct.
the question said somethin like
describe how it IS INDUSTRIALLY PRODUCED i think
IS- at the moment not how it can but how it actually is
INDUSTRIALLY PRODUCED - its produce from petrol coz the production from cellulose is not feasible or else we wouldnt be studyinda whole effn cellulose topic
nd i reseached nd it says petrol is a natural resource
It's not wrong in the normal sense because cellulose is a natural resource and it can be used to industrially produce plastics similar to those made from polyethylene, but it depends upon how strict the marking criteria is for the question. I think if you used cellulose you will probably still get marks.
