Hydroquinone → HCID 70478473, compound

Participants

Reaction Steps

Hydroquinone (45.6 g) was dissolved in a solution of sodium hydroxide (33.2 g) in water (332 ml) and to the resulting solution was added dropwise valeryl chloride (100 g), while maintaining the temperature at 3° to 6° C. The reaction was allowed to proceed at 15° C. for 1 hour. After reaction, the mixture was extracted with benzene and the benzene extract was washed with dil. sodium hydroxide solution to remove unreacted hydroquinone. The solvent was removed from the extract and the residue was distilled under a reduced pressure to give crude crystals (40 g) which were recrystallized from ethanol to give hydroquinone divalerate (36 g). b.p. 155°-157° C./1 mmHg.
