A photochemical liquid phase reactor, which is especially suitable for use in the production of oximes from cycloalkanes in the presence of a solvent, has a central stirrer around which is a plurality of lamps, the diameter of a lamp being D, the inter-lamp separation is 0.3-2D, the lamp-stirrer separation is 0.05-0.5D, and the separation between the lamps and the wall is at least 0.5D. The reactor may be cylindrical with the stirrer at the axis and the lamps disposed on a circle about the axis. The stirrer may be rectangular (7 in Fig. 1, not shown), or anchor shaped (Fig. 3, not shown), and generally operates at 40-200 rpm. The cell may be cooled by elements 8, coils 10, or a cooling jacket 9 (Fig. 4, not shown). In Figs. 5 and 6 (not shown) are shown arrangements having a plurality of cells in series. In the reactor of Fig. 5, liquid flows in the direction of the arrows through cells 11 having perforate partitions 14 and stirrers 12. In the arrangement of Fig. 6, liquid flows to reactors 15, 17, 19, 21, 23, and 25 through coolers 16, 18, 20, 22, 24, and 26.

    Abstract: 1,136,747. Cyclododecane oxime. BADISCHE ANILIN- & SODA-FABRIK A.G. 20 April, 1966 [21 April, 1965], No. 17225/66. Heading C2C. Cyclododecane is converted to its oxime by treating a solution of cyclododecane in chlorobenzene with a nitrosating agent and with light having a wavelength of 360-600 millimicrons while mixing the reaction mixture with turbulence, the cyclododecane oxime being removed from the reaction mixture outside the reaction zone by extraction with strong sulphuric acid. Suitable nitrosating agents are, for example, nitrosyl chloride or compounds which form nitrosyl chloride in the reaction medium. If desired, the process may be carried out in the presence of hydrogen chloride.

    Abstract: In a continuous process for the photonitrosation of cycloalkanes, a concentration gradient in respect of the photo-sensitive substance is produced in the solution to be irradiated, the concentration gradient being such that the concentration of the photosensitive substance in the reaction medium adjacent to the light transmitting surface is at most half the concentration in the rest of the reaction medium. The cycloalkanes may have 5 to 12 carbon atoms, and may be reacted in the temperature range - 30 DEG to + 30 DEG C. with for example nitrosyl chloride in amount to give from 0.3% to 0.5% by weight in the reaction mixture of nitrous oxide and chlorine under the influence of light having a wave-length of 360 to 600 millimicrons, advantageously in the presence of hydrogen chloride. If a solvent is needed it may be benzene, chloroform, ethylene chloride or glacial acetic acid. The example relates to the nitrosation of cyclohexane, in which a solution of nitrosyl chloride in cyclohexane saturated with hydrogen chloride is exposed at 18 DEG to 20 DEG C. to a mercury vapour lamp to give cyclohexanone oxime hydrochloride.
