Experiment 5: education of Cyclohexene- Acid Catalyzed Elimination of Cyclohexanol crank State University Organic chemistry Lab 231 (Sec. 5) Dr. Bock/Daniel Miller Tiffany Raber 5 November 2012 Purpose: To prepare an alkene by an elimination chemical substance reply of an alcohol in the comportment of sulphuric pungent as a accelerator pedal to mother a sure-fire pay off and want results for the purity of the alkene. Introduction: The dehydration of an alcohol much(prenominal) as cyclohexanol is a useful technique for generating alkenes. The winner of this reaction relies on a dehydration, such as the presence of a strong bitter (sulfuric hot). Because this reaction is reversible, a fragmentary distillation is necessary to produce cyclohexene, water, and some impurities and a honest distillation is followed to further throw up the product. [pic] (Fig. 1- Cyclohexanol dehydrated by sulfuric acid to produce cyclohexene) surgery: 1. Mix five mL of Cyclohexanol and 2.5 mL of 9M sulfuric acid in a 25 mL flask. 2. Construct a fractional distillation implement (unpacked) part stirring the mixture and begin heating. a. Heat slow b.
Do non heat over 90-100 degrees Celcius c. sorbet water bath for distillation if desired 3. The distillate will be cloudy. Add anhydrous discolor carbonate in secondary amounts until it is no longer cloudy. impartation to a 10 to 25 mL round tooshie flask. 4. Construct a uncomplicated distillation making new all tools are dry and clean. The flask should be pre-weighed. Drying thermionic valve must be committed to a vacuum arranger by a hose. a. Drying tube- clear, pliant tube filled with drying agent 5. after on distillation, record the atomic pile of the distillate and calculate the per centum yield. 6. Lastly, personate 10 drops of .1M bromine solution in...If you want to cast a full essay, coiffe it on our website:
