Abstract
A method of producing a cycloalkanone oxime by a photochemical reaction of a cycloalkane with a photo nitrosating agent in a liquid by light irradiation includes irradiating the liquid with a light source configured to emit light satisfying conditions that, in an emission energy distribution with respect to wavelength of light, a wavelength providing a maximum value of emission energy is 550 nm to 700 nm and a continuous wavelength range including the wavelength providing the maximum value and outputting energy of or over 5% of the maximum value is equal to or less than 150 nm, wherein a ratio ηE/V of a light irradiation energy ηE out of electric power E input into the light source to a reaction volume V which is a volume of a space for the photochemical reaction of the cycloalkane with the photo nitrosating agent is equal to or greater than 5.5 w/L.
