Reaction Steps
100 g of cyclohexene-(1)-dione-(3,6)-tetramethyl ketal were dissolved in 1500 g of n-butanol at 20° C. and the batch was acidified while stirring with 0.005 g of p-toluenesulfonic acid. After about 10 minutes the batch was heated for 30 minutes to 90° C., subsequently neutralized with NaOCH3, the formed methanol and the solvent were completely evaporated under slightly reduced pressure and subsequently the reaction product was submitted to a fractionating distillation. 65.3 g of hydroquinone dibutyl ether having a melting point of 46° C. distilled over under a pressure of 5 mm Hg at a temperature of from 125° to 135° C., which corresponded to a yield of 60% of the theory.
