Teflon stop-cock

A SOO-mL three-necked flask with a stop>cock at the bottom is fitted with a nitrogen inlet and a motor-driven mechanical stirrer with a Teflon paddle. The flask is flushed thoroughly with nitrogen while being flame-dri, and then 30 mL of mercury is introduced. A pan may be placed under the flask in case of breakage. The mercury is stirred vigorously as 4.5 g (0.196 mol) of sodium metal, cut into small pieces, is slowly added to it. The flask is capped with a rubber septum. [Pg.208]
