DISTILLATION OF CYCLOPENTADIENE Sample Clauses

DISTILLATION OF CYCLOPENTADIENE. Place dicyclopentadiene (10 mL) in a 25 mL round-bottomed flask (in the fumehood). Complete the set-up with a Vigreux column (for fractional distillation), an adapter and a condenser for distillation. Heat the dicyclopentadiene on a hot-plate until it refluxes briskly. The monomeric cyclopentadiene should start to distill within a few minutes. Continue to heat the dimer reagent to promote fairly rapid distillation and collect the cyclopentadiene into a receiver flask which is cooled to 0 °C using an ice-water bath. (Note 1). Do not allow the distillation temperature to exceed about 45 °C, which is slightly above the boiling point of cyclopentadiene (40-43 °C). After all the cyclopentadiene has been collected, stop the distillation and discard the unused residue from the reaction flask, into the liquid waste container. If the cyclopentadiene is cloudy, add a few pieces of anhydrous sodium sulfate (or anhydrous magnesium sulfate). Decant the dry cyclopentadiene from the drying agent for use in the experiment below.
