<p>The invention provides a production method of a cycloalkanone oxime by photonitrosation method using, as the light source, light emitting diodes which are the light source for the next generation as a replacement for an electric discharge lamp in which mercury, sodium or the like is enclosed. There is provided a production method of a cycloalkanone oxime by a photochemical reaction of a cycloalkane with a photo nitrosating agent in a liquid by light irradiation. The method uses a light source configured to emit light satisfying conditions that, in an emission energy distribution with respect to wavelength of the light source, a wavelength providing a maximum value of emission energy or peak intensity is in a range of 550 nm to 700 nm and a wavelength range outputting energy of or over 5% intensity of the peak intensity is equal to or less than 150 nm. A ratio ·E/V of a light irradiation energy ·E out of electric power E input into the light source to a reaction volume V for the light irradiation is equal to or greater than 5.5 w/L.</p> |
