Experimental Information
Special Equipment
Each pair of students will need three unique pieces of equipment: an alumina-bead catalyst tube, a palladium catalyst tube and a U-shaped cold trap . All pieces should be constructed prior to the laboratory period. All three pieces can be used indefinitely. The alumina-bead catalyst tube (Figure 1) is constructed from a 20-cm length of 6-mm i.d. borosilicate glass tubing and is filled with 1.75 g of acidified alumina beads (100 mesh) held in place by two small plugs of steel wool.
