実験手順

To 1.2 L of water, 223.2 g (1.09 mol) of sodium hydrosulfite, 1.0 L of cyclohexane, 200.0 g (908 mmol) of 2,6-di-tert-butyl-1,4-benzoquinone and 20.7 g (90.9 mmol) of benzyltriethylammonium chloride were added and the mixture was stirred for 1 hour at 40° C. The reaction mixture was subjected to liquid-liquid separation and the aqueous layer was discarded. The organic layer was washed with 400 mL of water to give a solution of 2,6-di-tert-butylhydroquinone in cyclohexane.
