Hydroquinone → HCID 283232, compound

Participants

Reaction Steps

A solution of hydroquinone (150 grams, 1.36 moles) in 2B denatured ethanol (500 milliliters) was added to a stirred reaction vessel having a nitrogen blanket. Next, a 64 wt.% aqueous solution of hydrazine (75 milliliters, 1.5 moles) was added to the vessel. This reaction mixture was allowed to stir for a few minutes and then filtered. The resulting filter cake was washed with 2B denatured ethanol and dried at 50° C. under a vacuum. The yield was 83.4% by weight, based on the amount of hydroquinone employed. The remaining product stayed dissolved in the ethanol filtrate and is recoverable by reusing the solvent in a subsequent reaction.
