Sue and I really enjoyed working with you for three great days! As our pilot group for the Chm 555 course, we will remember you all as our test group! Thanks for your enthusiasm and hard work!
We hope you will make productive use of these techniques. If you have any questions, please write to me (xenon@creighton.edu).
Best wishes to you all!
-Bruce and Sue
The workshop will also include the preparation and experimentation with several gases such as SO2, Cl2, H2S and SiH4 that are easily prepared but best suited for classroom demonstrations rather than student activities. During this workshop participants will use a gas generation kit and will practice and master the techniques of gas-generation using syringes. Participants will then perform numerous experiments using gas-filled syringes.
Advanced techniques will be addressed in the latter part of the workshop. In particular, participants will work with a glass-encased hetereogenous palladium catalyst tube suitable for demonstrating gas phase reactions in the classroom or teaching laboratory. The catalyst tube can be used to demonstrate a wide variety of reactions including oxidation of hydrocarbons with air, oxidation of carbon monoxide with air, hydrogenation of ethene, oxidation of ammonia with oxygen, oxidation of methane with nitrogen dioxide, oxidation of methane and dinitrogen monoxide, the reaction between hydrogen and nitrogen monoxide, and others.
