Chemical Technology IV
Course Description
This will be the fifth and the final semester of your ChemTec sequence. The class will meet on Thursday evening and on Saturdays. This semester we will complete our coverage of Organic Chemistry. Operation and/or data interpretation of two new instruments will also be covered. These are the nuclear magnetic resonance spectrometer (NMR), and the mass spectrometer. We will expand our use of the infrared spectrophotometer (IR), the gas chromatograph (GC), the high performance liquid chromatograph (HPLC) and the ultra violet spectrophotometer (UV Spec). During the semester you will be required to identify a general unknown. The analysis will involve collections of physical properties (b.p., m.p., etc.) and interpretation of instrumental analysis (IR, NMR and Mass Spec.). Ample time is allotted at the end of each Saturday lab for students to work on their general unknowns.
We will also continue to use the OWL (Online Web-based Learning) system as an assessment tool. In fact, your performance in the OWL system will count as one of your four, 100 point exams.

Exp. #
Title of Experiment
Purpose: State the purpose of the experiment and present a brief overview of how this will be achieved; i.e., techniques involved.
Reactions: Write the synthesis reaction.
Procedure: In most cases, the lab procedure will come directly from a lab manual or Instructor's Handout. Consequently, referencing this material may satisfy this section.
Procedure
Modifications: Were any changes made to the referenced procedure?
Data: These are all the measurements (weights, volumes, absorbances, etc.) taken during the lab. A unit must accompany each data entry. Erroneous data must never be erased but rather one line should be drawn through it. Whenever possible, data should be presented in a data table. The table should be constructed before coming to lab. A table of physical constants (CRC) for all organic reactant and product must be included in this section.
Calculations: These are the arithmetical manipulations performed on the data entries. If a particular calculation is to be repeated several times, then only one sample calculation need be demonstrated. Remember, whenever data is used in a calculation, its unit must also be included in the calculation.
Results: These are the results of the calculations. Whenever possible, put results in table form. Remember units.
Conclusion: The conclusion refers back to the purpose of the experiment by answering the question(s) posed in the purpose. Experimental results are restated in the conclusion.
Lab reports will be graded on the following criteria:
1) Neatness and Organization
2) Completeness
3) Calculations
4) Conclusions
5) Accuracy of Results

SAFETY RULES
Statement on Safety Rules: You must observe the following lab instructions that are given for your safety and the safety of other students in your class.
1. Safety glasses must be worn in the laboratory at all times. Safety glasses may be purchased in the bookstore.
2. Whenever an accident occurs, notify your instructor immediately.
3. When heating a substance in a test tube, never point the open end of the test tube at yourself or your neighbors.
4. Whenever using a Bunsen burner, make sure that long hair is tied back.
5. When attempting to detect chemical odors, exercise extreme caution. Keep your face a good distance away from the unknown substance and use your open hand to gently waft the vapors toward your nose.
6. Never taste a chemical.
7. Avoid touching hot objects, such as the barrel of a gas burner.
8. When diluting acids with water, always pour the acid into the water carefully. Do not pour water into acids. Remember, ...always add acid to water like you oughta.
9. If any chemical is spilled or splashed on your skin, flush the affected area with large amounts of water. If you splash chemicals in your eyes, use the eye wash immediately. In the case of larger spills, use the emergency safety showers. Report the occurrence to the instructor.
10. Always read the label on the reagent bottle before using the substance in the bottle.
11. When dispensing liquid reagents from a reagent bottle, always hold the bottle with the label facing the palm of your hand and pour out the side opposite the label.
12. To prevent contamination of reagents, always replace the cap from a reagent bottle immediately after using it.
13. Always heat a volatile, flammable substance in a water bath or steam bath, preferably under a hood. Never use a direct flame.
14. Shoes must be worn in the lab at all times (i.e., no sandals).
15. No food, drinks or smoking are allowed in the lab.
16. Familiarize yourself with the location at the eyewash, the safety shower, the fire extinguisher and the fire blanket.
17. If you are unsure exactly which chemical to use or how to do a procedure, ask your instructor before you proceed.
