2-Mercaptoethanol → HCID 14362083, compound

Participants

Reaction Steps

2-Mercaptoethanol (25.9 ml, 0.368 mole) is added in a single amount to a suspension of p-benzoquinone (80 g, 0.736 mole) in absolute ethanol (500 ml), with stirring and while bubbling nitrogen through the suspension. The temperature rises from 22° C. to 45° C. within 30 seconds and the mixture becomes a homogeneous red-brown. At the end of 15 minutes, a precipitate appears. The mixture is left to stand with stirring for 2 hours and filtered through a no. 4 frit. The orange-red precipitate is washed with 3×50 ml of cold ethanol and dried. Orange crystals are obtained
