Biofabrics derived from living organisms such as seaweed or bacteria have been proposed as a potential alternative to conventional fibers. In this science project, you will make several biofabrics from alginate ...

This resource discusses using potatoes to make plastics and investigates the use of plasticizers.

Many people would argue that one of the ultimate goals of green chemistry should be to solely use water as a solvent if a solvent is needed at all. For reactions where water is not an option, a choice must be made from a wide variety of organic solvents. Recently room temperature ionic liquids (RTIL) have been receiving a lot of attention because of their chemical and thermal stability, low vapor ...

In this activity, dried anthocyanin-containing flowers are combined with acidic, basic, and neutral powders using mortars and pestles in a demonstration of mechanochemistry. Students first research which solids they would like to use for this activity on the basis of maximum efficacy and minimum hazard. The data that they collect are used to inform the instructor as to which chemicals are to be ...

Analysis of trace metals and organic substances often relies on the use of
organic solvent-based extractions. In this laboratory exercise, students
will use analytical chemistry to determine heavy metals from water samples using a greener, micelle-mediated extraction procedure called cloud-point extraction. Water samples are treated with a chelating agent, ammonium pyrrolidine dithiocarbamate ...

Scarcer raw materials and climate change are scientific facts that make it necessary to enhance energy efficiency and to recycle raw material. Fundamental researchers at universities as well as in industry agree that light-emitting diodes (LEDs) are the most efficient and sustainable light sources of the future. Chemistry plays a significant role in the development of white, energy-efficient LEDs ...

Heterocyclic compounds have a wide range of applications and properties. They are often antimicrobial agents, can inhibit specific enzymes, and are generally useful in organic synthesis. This experiment provides instructors with a variety of heterocyclic compounds that can be synthesized quickly with the aid of microwaves. While not a lot of Microwave-Assisted Organic Synthesis (MAOS) is taught at ...

Microwave-assisted organic synthesis is becoming a more common laboratory practice. The advantages of using microwave-assisted synthesis include shortened reaction time, lower energy costs, and cleaner reactions. This particular experiment explores a much greener Wittig reaction that doesn't require an inert atmosphere, a strong base (i.e., butyl lithium), or even a solvent. In addition to these ...

Trays such as those used in food packaging that contain regular arrangements of dimples can be used to represent layers of atoms in solid structures used in solar cell technology. For example, the square array of dimples in transparent plastic mini quiche trays or egg cartons can be used to depict layers within cubic or tetragonal unit cells. Multiple solid structures and ways to model those ...

This article describes a simple approach for measuring the octanol-water partition coefficient (Kow) of organic compounds using a simple miniature variation of the shake-flask method in an NMR tube, which can be quickly analyzed using a benchtop 1H NMR spectrometer. The article also details the scope and limitations of the method. Kow is an important metric for understanding bioaccumulation and ...

Coumarins represent an important class of natural and synthetic derivatives with interesting biological activities. The 3-carboxycoumarins have been intensely studied because new functionalities can be easily added via the carboxyl group. During this laboratory exercise, students prepare 7-hydroxy-3-carboxycoumarin using a one-pot, multi-step procedure in the absence of organic solvents. By using ...

This module is part of a collection of nine green chemistry teaching modules developed in the early 2000s by a team of faculty (Donna Narsavage-Heald, Trudy Dickneider, David Marx, Timothy Foley, Joan Wasilewski) led by Michael Cann at the University of Scranton and has been migrated to the GCTLC. The subjects of the modules are based on winners of the Green Chemistry Challenge Awards. The modules ...

The lesson outlines for the second semester of organic chemistry (Klein, Organic Chemistry, 4th ed) contain lesson objectives, homework problems (H) and in-class problems (B) to engage students. Selected lessons feature "green" organic reactions specific to the chapter coverage.

This resource highlights how organic chemistry contributes to agriculture.

This is a discussion prompt where students find a molecule they use in a personal care product, cleaning product, or processed food. They find the structure, relate components of the name to aspects of the structure, look up the product on the Environmental Working Group (EWG) or FDA websites, and look up the molecule in PubChem. At the end, they need to decide whether they are happy with their ...

An organic chemistry laboratory experiment illustrating the oxidation of primary and secondary alcohols to their corresponding aldehyde or ketones, respectively, is described. The procedure uses 30% aqueous hydrogen peroxide in the presence of a tungsten catalyst (sodium tungstate) using phase transfer catalysis. The described experiments illustrate basic organic reaction chemistry and techniques ...

In this experiment, students perform a Grignard reaction under air-free conditions to synthesize and isolate organometallic Ni(II) phosphine complex(es) that are used as pre-catalysts for a Suzuki-Miyaura Coupling reaction in tert-amyl alcohol.

One of the main advantages of doing green chemistry is that it can often be done on the benchtop without the need for a fume-hood. In this experiment water and ethanol are the only solvents used for both the reaction and purification steps and oxone is a safe oxidant whose only by-product is potassium sulfate.

The oxidation of aromatic aldehydes using oxone allows instructors to discuss green ...

A new green oxidation procedure was developed for the undergraduate organic teaching laboratories using Oxone and a catalytic quantity of sodium chloride for the conversion of borneol to camphor. This simple 1 h, room temperature reaction afforded high quality and yield of product, was environmentally friendly, and produced negligible quantities of hazardous waste. The experiment was performed ...

Applications of organic chemistry to modify the structure and surface properties of materials are becoming increasingly important and interdisciplinary as the dimensions of modern materials decrease.

The purpose of this lab is to introduce students to some basics of the chemistry of polymers. Polymer chemistry is often an afterthought in the General Chemistry curriculum, but polymers are very much present in students’ lives. The lab introduces the relationship between molecular structure (e.g., branched vs. linear, bulky vs small side groups) and bulk properties (e.g., flexibility). This lab ...

The purpose of this lab is to give students experience in the practical preparation of buffers and exploring buffer properties.
