실험 절차

3.5 g (15.1 mmol) of trichloroisocyanuric acid, 3.7 g (45.1 mmol) of sodium acetate and 10 mg (0.06 mmol) of TEMPO were suspended in 40 ml of methylene chloride in a 100 ml sulphonation flask and the suspension was cooled to (-7)-(-9)° C. while stirring. A solution of 5 g (38.4 mmol) of 1-octanol in 20 ml of methylene chloride was dosed in within 20 minutes, whereupon the mixture was held at (-7)-(-9)° C. for 80 minutes. Thereafter, the reaction had finished. For the working up, the white precipitate was filtered off and the filtrate was washed with sodium bicarbonate solution and with sodium chloride solution. Distillation of the crude product gave 4.5 g (91%) of octanal, GC content: (98.2%) (area percent).
