Preparation for Laboratory Class. Independent of the lab notebook and prior to entering the laboratory, you should have planned out (i) a balanced chemical equation, (ii) a procedural outline or flow chart, and (iii) physical and hazardous properties for each 1 chemical (including solvents) you plan to use in the experiment. Obtain this information from the Web – for example, if you look up the compound at the Aldrich Chemical Co web site http://www.sigmaaldrich.com/catalog/search/AdvancedSearchPage then follow the link to MSDS, the Material Safety Data Sheet will provide the appropriate information. (Please keep in mind that the MSDS info is geared to handling chemicals on the industrial scale.) II. Laboratory Notebook. Update your laboratory notebook during the day’s experiment, not afterwards. Use the passive voice, abbreviations and shorthand, when possible. During the lab period make notes on your actual procedure data, (ii) significant visual observations. DATE each page or entry. III. Laboratory Report. A written report is required for each experiment. The report layout is the usual one used in the sciences and should have the following titles: Introduction, Results, Discussion, Experimental Section, Conclusion, Acknowledgments and References (see below for details). The final draft of lab reports (and reaction products, if applicable) is generally due as announced in the lab. Breakdown of a full laboratory report: Introduction: Describe the chemistry goals for the experiment. Write a balanced chemical equation for the reaction, if any. Results & Discussion: O The percent yield along with an estimation of product purity by spectroscopic and/or chromatographic analyses should be provided o Spectra (usually IR and/or NMR) along with their interpretation, which means writing out descriptions of where the peaks are, and which atoms or groups caused those peaks, and why you assigned those atoms. In particular, evidence for the presence or absence of any possible contaminants should be addressed by a detailed examination of the spectra, using reference spectra when available. o A detailed mechanism using electron-pushing notation is usually required. Experimental Section: Describe the procedure which you carried out (as opposed to what you intended to do) using the passive voice, third person language. Be succinct, but do not leave out important details. We will learn how to write these by reading some from the original literature. Conclusion: Write a brief, coherent conclusion that focuses on the results involved in the experiment. Acknowledgment: Acknowledge any student whose data or graphics are used in your report. Do not acknowledge the teaching assistant or professor. References: Include a reference to the original literature in each formal report. If possible, use the Endnote application available in the Chemistry Computer Lab. Never include a reference without a reference to it (a “callout”) appearing somewhere in the text.

It is the responsibility of the student to inform the instructor of any necessary accommodations at the beginning of the course. Any student with a disability requiring accommodations should contact the Office of Disability Support Services. Laboratory safety rules • • • • • • • • • • Wear safety goggles (eye protection) at all times when in the laboratory. This is a departmental and state regulation. Do not eat or drink in the laboratory. Know the location and use of the nearest fire extinguisher, nearest First Aid kit, nearest eye wash station, nearest safety shower, and nearest exit designated for evacuation. You will be advised of the locations on the first day of the lab. Know the location of the Material Safety Data Sheets (MSDS) and know that you have access to them. You are protected by the right to know law. Know the NFPA (National Fire Protection Association) Hazardous Material Classification Codes. Report all accidents, even minor injuries, to the instructor at once. In case of an organic chemical spilled on your person, flush with water, wash with soap, rinse with water, rinse with ethyl alcohol, wash with soap, and rinse with water. Pat dry. Never taste chemicals or solutions. Minimize the inhalation of organic vapors by using the smallest amounts of materials and utilizing the hood as much as possible. Check the MSDS if you have questions. Dispose of all wastes properly. Read labels on bottles! Keep bench and floor clean. Before leaving the laboratory, be sure that the water, steam, heaters, and gas cocks are shut off. 3 List of Experiments and grading (100 pts) for CHEM 333 lab Week 1 1/20 2 1/27 3 2/3 4 2/10 5 2/17 6 2/24 7 3/2 8 3/9 10 3/23 11 3/30 12 4/6 13 4/13 14 4/20 15 4/27 16 5/4 Experiment Lecture: Introduction to Polymers and Nomenclature; Molecular Weights Lecture: Structure and Morphology; Characterization and Testing Lecture: Free Radical (Addition) Polymerization Lab#1: Methyl Methacrylate polymer Lab#2: Polystyrene Lecture: Ionic Polymerization Lecture: Copolymerization, Ziegler-Natta Catalysis Step (Condensation) Polymerization Midterm exam Lab#3: Polyesters Lab#4: Polyamides Lab#5: Polyurethane Form Lab#6: Preparation of Styrene- Maleic Anhydride Random Copolymer Lab#7: Ring Opening Metathesis Polymerization of Norbornene Final exam Lab check out 4
