Unformatted text preview: Chemistry 2510 Read in Padias, pp 4-16. Introductory Experimental Organic Chemistry Laboratory Notebook Spring 2010 All information necessary to safely perform an experiment must be in your notebook, as you will not be allowed to bring a nything except your notebook into the lab (i.e. no text, lab handouts, etc.). There may be unannounced, spot checks of the notebooks, including safety information, at anytime during a lab. These spot checks will assign points to certain information and these points will part of the overall lab notebook grade/safety policy adherence grade in the course. The laboratory notebook must be a permanently bound notebook with sequentially numbered pages. The notebook should have no ability to add or delete (thus the numbering) pages. There are several styles that you may use. One convenient notebook, because it includes a copy page and is pre-numbered, is “Student Lab Notebook” by Hayden McNeill Specialty Products. These are available in bookstores and online. A less expensive choice would be the “grade school” marbled-front notebook. They are inexpensive and are widely available. If you choose this type of notebook the pages need to be entirely numbered by hand in ink at the start of the semester. Whatever style of laboratory notebook you select, be sure to follow the guidelines below. A laboratory notebook is a complete record of your experimental work. All entries in the notebook must be made in permanent ink (preferably black ink) and dated. You must n ever erase or use white-out. The laboratory notebook is the scientist’s most valuable possession and a very important form of technical writing. You should learn to keep a good scientific notebook. Be sure you follow the instructions in your textbook and those given below. Setting up your notebook. Follow these instructions exactly! 1. On the outside cover of your notebook PRINT your name, lab name (Organic Chemistry Laboratory), and lab day/time. 2. Number every page (front and back) before you do anything else unless it is prenumbered)! 3. Leave the first few pages empty for the “Record of Contents” or fill in the “Table of Contents” on the inside front cover. Each week as you write up each new experiment update the contents page. Format for the Organic Chemistry Laboratory Notebook These five steps should be performed before coming to the laboratory: 1. You should start each new experiment on a new page. 2. At the top of the page, print your name, date of the experiment, expt. # (from the lab handouts), locker #, section day, TA name, and experiment title with a reference to where the procedure is found in the textbook, handout, or other source. 3. When performing a reaction, write a balanced reaction using structural formulas. 4. Construct a table of reagents, reactants, and products. Draw the structure of each material used in the experiment. List important physical properties, and any hazards . Also include waster disposal instructions for everything. 5. Procedure: You will not be allowed to have your textbook or syllabus in the laboratory - only your lab notebook. You should write a concise, (there is no need to copy the procedure word for word) accurate experimental plan into your notebook. Be sure to include a section on cleaning up (waste treatment/disposal). You will want to draw any new glassware set-ups or other apparatuses that you are not familiar with. Chemistry 2510 Introductory Experimental Organic Chemistry Spring 2010 Laboratory Notebook During the laboratory session: 6. Record all observations (colors, smells, melting points, refractive indexes, optical rotations, etc.) directly into the notebook. 7. A representation of any TLC plates run during the lab should be included in your notebook, with Rf’s for all spots calculated. After the laboratory: 8. Show any calculations (% yield, % recovery, etc.) as your results (if you have repetitive calculations in an experiment, show at least one sample calculation). 9. A copy of all original data (i.e. IR spectra (with major peak assignments), TLC’s, other spectra, etc.) should always be stapled into your notebook (this means making duplicates of spectra that must be submitted with your reports!). 10. Major peak assignments on IR spectra should be noted on the spectrum included in the notebook (as well as in your report). 11. Any calculations (specific rotation, % e.e., percent yield, percent recovery, etc.) should always be shown in your notebook (as well as sample calculations in your reports). 12. Conclusions should also be included on this page. These are very concise statements (identification of an unknown, etc.). 13. Hand in any result sheets/reports as requested. Items 1 through 13 above are all fair game for the notebook grading at the end of the course (or as a spot check at anytime by your TA). Your TA is not authorized to grant exceptions to any of these requirements. ...
