Hydroquinone (30 g) was dissolved in n-propanol (70 ml) at 70° C. The hot solution was introduced into the high pressure autoclave. The solution was subjected to compressed ethylene oxide of 300 bar. The high pressure autoclave was kept for 2 h at 80° C. The solution was then cooled down to room temperature within 5 days. The crystals were filtered off and washed 4 times with cold n-propanol (5 ml). The crystals were then dried in the drying cabinet at 70° C.
