Cited section: Part A: 25 mL cyclohexane plus 25 mL p-xylene; top of thermometer bulb midway in opening to condenser; Part A: heating mantle on ring clamp, clay boiling chip, roughly one drop per second; Part A and B: record head temperature every 2 mL until 45 mL collected; Part B: 100 mL round-bottom flask and fractionating column; proceed as above; Recording of Results: paired temperature-volume plots, no azeotrope for this pair, volume is not composition; Experimental Notes item 2 mentions condenser water flow; no inlet/outlet direction established.
