This course covers the most significant emerging field in modern chemistry, namely,
Green chemistry, the field which focuses upon the reinvention of chemistry such that pollution can be avoided. The chemical nature and action of pollutants of the atmosphere, land, and water sources will be presented along with prospects for their minimization, and approaches for their eradication. Examples of successful green chemistry developments will be highlighted. Themes woven throughout the course include emerging concepts for guiding green chemistry, environmental toxicology, the development of green oxidants, and an identification of toxins, especially persistent toxins, where elimination will require new green chemistry. A significant effort has been made to produce a course suitable for an interdisciplinary audience and recent classes have come from diverse backgrounds throughout the university.
The course aims to:
The ultimate aim of green chemistry is to entirely cut down the stream of chemicals pouring into the environment
To think prospectively about how to change our education subjects to be sustainable learning tools by Investigating examples of green chemistry applications relevant to students
Green Chemistry (Chemistry 442), Fall- 2015
To understand the important role of the green chemistry and how to deal with it in our practical life
Teach the fundamentals of greener chemical processes including the political
and environmental drivers that impact on the chemical industry.
Familiarize students with legislation and control of hazardous substances.
Provide students with the skills to propose a synthetic plan for any molecule
Give the students the opportunity to perform research work as part of an active research group within the Department.
Prepare students for employment as scientists in industry, academia or a research institute by direct entry or following further study.
Microwave mediated reactions
Applications of photochemistry, electrochemistry, sonochemistry and other alternative resources for greener applications (like fuel cells)
The applications of hydrogen peroxide as greener solvents
Student Learning Objectives:
1. Understand and identify structure/function relationships with respect to chemical properties, biological activity, and product performance. Be able to rank competing synthetic methods using the twelve principles of Green Chemistry along with other technical metrics
2. To understand the environmental consequences of chemical manufacturing and illustrate how these may be minimized
3. Introduce the 12 principles of green chemistry as well as the tools of green chemistry including the use of alternative feedstocks or starting material reagents, solvents, target molecules, and catalysts.
4. Demonstrate an understanding of green approaches to industrial scale chemical processes.
5. Show knowledge of specific green alternatives including alternative solvents, reactor design, atom efficient reactions, energy issues and full life cycle analysis.
6. Propose possible synthetic routes for almost any chemical.
7. Recognize and understand the major methods of separation, purification, and characterization of compounds.
8. Use scientific skills in a research project on green chemistry.
9. Demonstrate transferable skills in oral presentation, report writing and the use of information technology.
10. Students will understand how to assess the environmental impact of chemical operations and understand the methods for their minimization and be able to suggest alternative green methods to current processes .
Course Evaluation :
Weekly Assignments :
The assignments for the class will focus on developing good presentation skills and developing the ability to critically evaluate the literature. Detailed descriptions of the assignments will be posted on the course website.
Literature Summaries :
Green Chemistry (Chemistry 442), Fall- 2015
Every Monday, one quarter of the class will be expected to turn in a typed summary of one of the journal articles assigned for the prior week and to lead the discussion of the articles during Monday’s class. These summaries will follow an online discussion outside of the classroom, using the Blackboard environment as a tool to facilitate discussion during the previous week. Please refer to the handout
‘ Everyone is expected to come to class prepared to discuss the journal articles assigned for that week.
Midterm Paper:
Midterm paper critiquing a specific recent development in green chemistry will be due at the end of the midterm week. Students are encouraged to refer to Real World
Cases in Green Chemistry for an example on how to structure the paper. The paper can be written as if it were an additional chapter in the book. Topics are easily found from other or more recent Presidential Green Chemistry Awards that are not covered in the text.
Final Project :
The final project for the course will be a 15 minute in class presentation of your critical evaluation of a green chemical process or procedure that was recently developed. These critiques should closely follow the outline used in each Chapter of
Real World Cases in Green Chemistry. Homework assignments throughout the course will be geared towards helping you to assemble and prepare this 15 minute
PowerPoint presentation.
Green Chemistry presentation rubric student performance will be on individual basis
Green chemistry project rubric will be on individual basis
Green week
Green chemistry Wiki project : A Wiki is a self-made website. Students will be researching an environmentally unfriendly product (conventional product) and comparing it to its green , environmentally friendly, counterpart (innovative product).
They will be using www.wikispaces.com
