Participants

Reaction Steps

Hydroquinone (55 g) was dissolved in a solution of sodium hydroxide (40 g) in water (300 ml) and to the resulting solution was added dropwise butyryl chloride (100 g), while maintaining the temperature at 3° to 6° C. The reaction was allowed to proceed at 10° to 13° C. for 4 hours. After reaction, the mixture was extracted with benzene and the benzene extract was washed with dil. sodium hydroxide solution. The solvent was removed from the extract and the residue was dissolved in ethanol (300 ml). Recrystallization was effected by addition of water (80 ml) to the solution to give hydroquinone dibutyrate (108 g). m.p. 42°-43° C.
