Which solvent would be the best choice for use as an extraction solvent in a separatory funnel with an aqueous solution of NaHCO3 followed by rotoevaporation? Hint: Consider the ability of the solvent to dissolve a wide range of substances, its miscibility with water, and its ability to evaporate the solvent easily by rotoevaporation. ethylene glycol
0.56 g 1,4‐dimethoxybenzene, 0.9 mL 2‐chloro‐2‐methylpropane, 5 mL nitrobenzene and 0.52 g graphite were combined, and the mixture was refluxed for 1.5 hours. It was then cooled to room temperature and filtered. The filtered graphite was washed with 15 mL hexane. The filtrate was distilled under vacuum to remove any remaining 1,4‐dimethoxybenzene, 2‐chloro‐2‐ methylpropane and nitrobenzene (6.3 g), yielding 0.44 g 1,4‐di‐tert‐butyl‐2,5‐dimethoxybenzene (43.4% yield).
