Abstract:
1. A method of producing a cycloalkanone oxime comprising photochemically reacting a cycloalkane with a photo nitrosating agent in a liquid by light irradiation with a light source configured to emit light satisfying conditions that, in an emission energy distribution with respect to wavelength of light, a wavelength at which emission energy has a maximum value of 550 nm to 700 nm and a continuous wavelength range including the wavelength at which the emission energy has a maximum value and outputting energy of or over 5% strength of the maximum value is equal to or less than 150 nm, wherein an irradiation distance in the liquid is equal to or greater than 200 mm, concentration of the photo nitrosating agent in the liquid is 0.1 mol % to 0.5 mol %, and the light source is a light emitting diode and has an energy conversion efficiency equal to or greater than 10%, wherein the energy conversion efficiency is an integrated value of emission energy in a wavelength range of 400 to 780 nm with respect to an input electric power per each light emitting diode.
