PRE-LAB REPORT GUIDELINESMPORTANT: Make sure that you always follow the proper laboratory safety protocol (refer to the course syllabus) BEFORE going to the lab.1The synthesis of Dibenzalacetone (period 1) is done individually.In preperation for lab, your prelab report should include the following:CHEM ISTRY 14CL ALDOL CONDENSATION SYNTHESIS OF DIBENZALACETONE PRE-LAB REPORT GUIDELINES Pre-lab report must be written inside your lab notebook. MPORTANT: Make sure that you always follow the proper laboratory safety protocol (refer to the course syllabus) BEFORE going to the lab. 1 The synthesis of Dibenzalacetone (period 1) is done individually. In preperation for lab, your prelab report should include the following: 1. Introduction : In this section outline the goal(s) of the experiment as well as the experimental techniques that you will be using to purify and isolate the desired product(s). 2. Prepare a half-page flow chart of the experimental design; indicate on your flow chart a time plan for the experiment that will allow you to complete the work in 2 hours. Be sure to use the time the reaction is stirring for other activities. Make sure to reference the procedural steps in the lab manual. 3. List the equipment that you will need to have on hand for each step in the procedure for period 1. 4. Provide MSDS information for the following chemicals: Benzaldehyde & Acetone You should record the following MSDS information in your notebook for the chemicals listed above. (Printouts directly from the Web pages will NOT be accepted!!) (a) Product Name (b) Chemical Formula (c) Formula Weight (d) Melting Point; Boiling Point and Density (also known as specific gravity) (e) Health Hazard Data (summarize in your own words) (f) Spill and Disposal procedures (summarize in your own words)CHEMISTRY 14CL Aldol Condensation - Synthesis of Dibenzalacetone PRE-LAB REPORT GUIDELINES (Continue) (In addition to the MSDS sites provided by the University of California, http://www1.ucop.edu/oehsp/msds.html you may want to look at http://www.chemnetbase.com/ Click on “Combined Chemical Dictionary (CCD)” and start the search.) 5. Draw the three possible isomers of dibenzalacetone. (Hint: Consider the stereochemistry around the two double bonds. Remember that there is no free rotation around a double bond.) Give BOTH the common and IUPAC names for each of the isomer structure. Note: There is NO pre-lab report associated with the Molecular Modeling
