Environmental and Green Chemistry
|Unit level||Level 2|
|Teaching period(s)||Semester 2|
|Offered by||Department of Chemistry|
|Available as a free choice unit?||No|
Weeks 1 - 2 Green Chemistry (Dr. G. Perry, 4 lectures)
- What is 'Green Chemistry' : environmental issues to be overcome in the 21st century
- Designing cleaner, more efficient reactions: use of catalysis, enzymes, light and renewable feedstocks
Examples of green chemical reactions: from the bench to production.
Weeks 3 – 4 Process Chemistry (Dr. G. Perry, 3 lectures + workshop)
- Exemplification of route design and optimization: what makes a good process?
- Key bond-forming reactions in industrial chemistry: what are the problems?
- Selected case histories from the pharmaceutical and fine chemicals industries
Weeks 5 – 8 Weeks 9 -11Novel Feedstocks for Green Chemistry (Dr F. Mair, 6 lectures + Workshop)New Sources of Chemicals (Dr. F. S. Mair; 6 lectures):
- Survey of common materials currently sourced from petrochemicals
- Discussion of alternative renewable feedstocks to replace petrochemical feedstocks: sugars, lignin, fats, biomass, CO2.
Week 9-12 Atmospheric Chemistry (Dr. A. Brisdon, 7 lectures +Workshop)
- A survey of the composition of the atmosphere and the natural chemical and physical processes that lead to this composition, including methods used to determine atmospheric concentrations.
- Anthropogenic effects on the atmosphere
- Discussion of key environmental challenges arising from anthropogenic effects.
Week 12 Workshops: Feed-forward of common errors from previous years.
The course unit aims to:
- Provide the student with an understanding of the impact which chemistry can have on the environment and of how this impact may be quantified and minimized.
- Provide an insight into how manufacturing processes can be developed which have a minimal environmental footprint.
- Highlight recent advances in chemical synthesis which minimize waste and increase overall chemical efficiency.
- Describe the general composition of the atmosphere and how solar energy drives chemistry, photochemistry and physical transport processes.
- Describe the theory of classical and state-of-the-art analytical techniques and demonstrates their use in environmental chemistry through case studies.
- Describe anthropogenic effects on the atmosphere and discuss some key environmental challenges.
- Highlight how alternative feedstocks can allow access to key chemicals beyond the petrochemical era.
Students successfully completing this unit should have developed the ability to:
Green Chemistry and Process Chemistry
- Demonstrate a knowledge of the key reactions and processes used in chemical industries;
- Understand the problems associated with performing large scale chemical syntheses;
- Demonstrate an understanding of the factors which contribute to the design and execution of efficient chemical syntheses.
- Understand chemical and physical processes which occur in the atmosphere and relate these to the natural composition of the atmosphere;
- Demonstrate a basic understanding of the methods and instrumentation for analysis of atmospheric composition;
- Demonstrate knowledge and understanding of the impacts anthopogenic emissions have on natural atmospheric chemistry, cycles and processes;
- Predict the likely atmospheric chemistry and ultimate fate of anthropogenic pollutants;
- Compare the relative environmental impacts of related anthropogenic pollutants.
- Identify likely sources of key feedstocks from sources other than petrochemicals
- Apply basic chemical principles to the harvesting and manipulation on non-traditional chemical feedstocks.
