Chem.2302K Fall 2020 Gh.Mandouma Lab 2: Dehydration of 1-Octanol to form 1-octene: Addition Reactions Lab Report Due: Friday 10/09/2020 (NO EXTENSION ALLOWED) Graphical Abstract: Purpose : Dehydration 1-octanol to afford 1-octene is done at moderate temperature under catalytic condition (phosphoric acid). 1-octanol has a higher boiling point (bp. 161 °C) than water and/or 1-octene (bp. 83 °C). The latter can therefore be distilled off (albeit with some water) the reaction mixture via a fractionating column attached to the reaction mixture. To fully recover the distilling 1-octene that may be trapped inside the column, aluminum foil must be used to wrap around the Vigreux fractionating column as well as the distilling head to keep them warm enough, and the distilling compound will keep flowing. Furthermore one must then separate 1-octene from residual water in a clean and dry separatory funnel and by further drying the organic compound with a convenient drying agent (anhydrous calcium chloride pellets) for 10-15 min. Filtering off the drying reagent will provide 1-octene for the subsequent bromine test and additional reactions as outlined below. Materials :
