Answer to Question #179799 in Organic Chemistry for Nomvula

Question

describe the distillation method used for cracking of dicyclopentene

Answer 1

.Two hundred milliliters of technical dicyclopentadiene is placed in a 500-ml. two-necked round-bottomed flask equipped with a thermometer and an upright Friedrichs-type condenser (through which water at 50° is circulated). The ground-glass outlet of the Friedrichs condenser is connected to the side arm of a simple distilling head fitted with a thermometer and attached to an efficient water-cooled condenser held in a vertical position. At the lower end of this condenser is a receiver which consists of a carefully weighed 500-ml. two-necked round-bottomed flask immersed in a Dry Ice bath and protected from the air by a calcium chloride drying tube.
