Yale-UNIDO University Curriculum


Yale-UNIDO University Curriculum- Overview

• It is still a chemistry course – There are atoms, molecules, chemical reactions, and long unpronounceable names!

• It is an environmental sustainability course focused on applying chemistry principles. There is a wide range of environmental and energy issues that are discussed.

• The course will place chemicals in the context of daily life and society.

• It is an analysis course. Students will learn how to use the tools of analysis to better understand and make science-based judgments about chemicals, materials, and products.

After this course students will be able to (i) analyze whether or not a chemical/chemical product is “green” and sustainable, and (ii) make recommendations on how chemicals and chemicals products can be improved to be greener.


• Intended for faculty who are looking to include more green chemistry in their curriculum by changing:

Their entire course

Semester long course (27 lectures) with PowerPoint slides, readings, class exercises, homework assignments, 2 midterms, final exam, and answer keys.

Sections of their course

Bridging topics to energy, innovation, analytical chemistry, recycling, and biodegradation.

Or to include individual topics and examples or exercises

Can be used with organic, inorganic, and general chemistry curriculum.

• Diverse multimedia content that encourages team work and hands-on learning.

• Copyright free.

Outline: 12 Principles of Green Chemistry


Safer Solvents and Auxiliaries

The use of auxiliary substances (solvents, separation agents, etc.) should be made unnecessary whenever possible and, when used, innocuous.


Solvents account for the vast majority of mass wasted in syntheses and processes. Moreover, many conventional solvents are toxic, flammable, and/or corrosive.

Solvents volatility and solubility have contributed to air, water and land pollution, have increased the risk of worker exposure, and have led to serious accidents.

Recovery and reuse, when possible, is often associated with energy-intensive distillation and sometimes cross contamination. In an effort to address all those shortcomings, chemists have started to search for safer solutions.

Case study: Coffee decaffeination

Conventional method of coffee decaffeination:

• Coffee decaffeination was performed in a chlorinated organic solvent, dichloromethane (DCM), exposure to which can lead to headaches, mental confusion, nausea, vomiting, dizziness andfatigue.

• Coffee beans were heated with steam and then exposed to DCM for decaffeination.

Image: Wikimedia Commons, Coffee Mechanical Separator, Aquapulp



• Soaking green coffee beans in water doubles their size, allowing the caffeine to dissolve into water inside the bean.

• Caffeine removal occurs in an extraction vessel (70 feet high,10 feet in diameter), suffused with carbon dioxide at roughly 90 °C and 250 atm. Caffeine diffuses into this scCO2. The beans enter at the top of the chamber and move toward the bottom over 5 hours.

• Decaffeinated beans at the bottom of the vessel are removed, dried and roasted.

• Recovery of dissolved caffeine occurs in an absorption chamber. A shower of water droplets leaches the caffeine out of the supercritical carbon dioxide. The caffeine in this aqueous extract is then often sold to soft-drink manufacturers and drug companies. The purified carbon dioxide is recirculated for further use.

Alternative method for coffee decaffeination:

Zosel, K. Practical Applications of Material Separation with Supercritical Gases. Angew. Chem., Int. Ed. 1978, 17, 702-709


Case study: Coffee decaffeination


• Delicate biomedical materials such as vaccines and tissues are conventionally sterilized with ethylene oxide - a carcinogenic, mutagenic, toxic, and flammable gas - or with gamma radiation, which is lethal to all cells.

• Both methods damage the materials they are sterilizing.

• Ethylene oxide persists in tissue.

Case study: Medical sterilization

Conventional medical sterilization:

• Development of a supercritical carbon dioxide (scCO2) based method for sterilization of biological material.

• NovaSterilis sterilization uses scCO2, peracetic acid, and small amounts of water at low temperatures and modest pressure to achieve rapid sterilization of sensitive biomaterials.

Case study: Replacing dichloromethane (DCM) in chromatography

Amgen’s Green Solvents for Chromatography in practice. If a compound suitably elutes in 5% DCM–MeOH, the bar chart predicts that 60% 3 : 1 EtOAc : EtOH in heptanes or 40% i-PrOH in heptanes would be a suitable starting point to evaluate greener solvent alternatives.

Amgen developed a guide to replace DCM with greener alternatives. DCM is known to be associated with respiratory and cardiovascular toxicity in humans, carcinogenicity, and genotoxicity.

The guide on the right compares the eluting power of different greener solvent mixtures with reference to DCM-Methanol.



Zoloft® is an anti-depressant and was once one of the best selling pharmaceuticals on the market.

Conventional sertraline synthesis:

• Synthesis was a three step process.

• Used 4 hazardous solvents (methylene chloride, tetrahydrofuran, toluene, and hexane).

Zoloft®

Case study: Manufacturing process for sertraline, the active ingredient in the popular drug Zoloft®



• The process was streamlined to a single step that is carried out in ethanol, a much less toxic solvent.

• The new process is also catalytic, cutting down on starting materials by 60%, 45%, and 20% for the three components of the reaction.

• The combined steps eliminated 310,000 pounds of titanium tetrachloride, 220,000 pounds of 50% sodium hydroxide, 330,000 pounds of 35% hydrochloric acid waste, and 970,000 pounds of solid titanium dioxide waste per year.

Molar Mass

What is the mass in grams of 1 molecule of sucrose?

1 mol sucrose = 342.30 g sucrose

1 mol sucrose = 6.022 x 1023 molecules of sucrose

x1 mol sucrose

6.022 x 1023 molecules of sucrose342.30 g sucrose

1 mol sucrose

= 5.68 x 10-22 g/molecule

Avogadro'sNumber


“1 mole of formaldehyde gas reacts with 1 mole of oxygen gas to form 1 mole of liquid water and 1 mole of carbon dioxide gas.”

What is implied…

“30 g H2CO reacts with 32 g O2 to form 18 g H2O and 44 g CO2”

H2CO (g) + O2 (g) H2O (l) + CO2 (g)

Writing and Balancing Equations


Stoichiometry of Chemical Reactions

You can use dimensional analysis…

Just like 1000 g = 1 kg

An amount of 6.48 mole of NH3 reacts with how many moles of O2?

5 mol O2 = 4 mol NH3

6.48 mol NH3 X 5 mol O2

4 mol NH3

= 8.10 mol O2

4 NH3 + 5 O2 4 NO + 6 H2O

Nature vs. Lab

• Chemical transformations happen at ambient temperatures

• Minimal waste• Utilize water as a solvent

and reagent• Complex molecules

seamlessly • Domino and Cascade

reactions• Enzymes• High selectively

• Chemical transformations happen high temperatures and high pressure

• Varying amount of waste produced

• Utilize petroleum-based solvents

• Complex molecules take skills specialized catalysts

• Step-be-step synthesis• Precious metal catalysts• Moderate selectivity


Designing an Ideal Green Reaction

1. Generate no waste or by-product/Use waste sources• Always addition reaction? No.• Must consider the whole picture.

2. High yield and high rate

3. Earth abundant feedstock and catalyst

4. Energy efficient• Does not require high external energy input.• UV light driven.• Microwave assisted.

5. No solvent or environmentally benign solvent• Water• Recyclable organic solvent• scCO2


Biomimicry

Biomimicry is the science and art of emulating nature's best biological ideas to solve human problems.

Bios = lifeMimic = to copy or emulate


“Pond scum may be a synonym for ‘primitive’, but the tiny organisms that compose it easily beat the human state of the art when it comes to capturing energy from the sun. Some purple bacteria answering to that unflattering description use light energy with almost 95% efficiency – more than four times that of the best man-made solar cells.”

2011 Presidential Green Chemistry Challenge Academic Award


Professor Bruce Lipshutz, University of California Santa Barbara Towards Ending Our Dependence on Organic Solvents

Most chemical manufacturing processes rely on organic solvents, which tend to be volatile, toxic, and flammable. Chemical manufacturers use billions of pounds of organic solvents each year, much of which becomes waste. Water itself cannot replace organic solvents as the medium for chemical reactions because many chemicals do not dissolve and do not react in water.

Professor Lipshutz has designed a safe surfactant that forms tiny droplets in water. Organic chemicals dissolve in these droplets and react efficiently, allowing water to replace organic solvents.
