35、0 drops per minute. Allow the apparatus to cool for approximately 15 minutes, then wash the condenser walls with three 5 to 10 ml portions of dry toluene. Force the water column back and forth in the bottom of the moisture trap to collect all the water and to mix the methylene blue thoroughly with t
36、he water, then slowly open tubing to move the blue tinted water, as an unbroken column into the graduated capillary. Add approximately 2ml-f dry toluene d.
