Versuchsvorschrift

1-Decene was supplied from a raw-material tank 4 using a high-pressure pump, and the raw material was preheated in an ozonization reaction vessel 3 at 20° C. The preheated raw material was then combined with the high-pressure carbon dioxide solution of ozone, and continuous ozonization proceeded in a stainless steel coil-shaped ozonization reaction section 1 having an inside diameter of 1 mm and a length of 26 cm and set to 20° C. The reaction mixture that exited from the ozonization vessel 3 was subsequently subjected to a continuous thermal decomposition reaction in a stainless steel coil-shaped decomposition reaction section 11 having an inside diameter of 1 mm and a length of 100 cm and set to 200° C. The residence time corresponding to the reaction time was 6 seconds in the ozonization reaction section and 24 seconds in the decomposition reaction section, making a total of 30 seconds. The product was passed via the pressure-regulating valve 30 and was dissolved in acetone placed in a gas-liquid separation device 40. Quantification of the acetone solution by FT-NMR using coumarin as an internal standard confirmed that 0.58 mmol of nonanoic acid and 0.63 mmol of nonanal were produced in 30 minutes.
