    摘要: PURPOSE:To obtain the titled compound useful as a raw material for surfactants, etc., by bringing a reaction solution partially into contact with sodium sulfite and returning the resultant reaction solution to the reaction system in reacting a saturated hydrocarbon with sulfur dioxide and oxygen in the absence of water in the reaction system by irradiation with light. CONSTITUTION:A saturated hydrocarbon is reacted with sulfur dioxide and oxygen in substantially the absence of water in a reaction system by irradiation with light at

    摘要: PURPOSE: To produce the titled compound continuously, in high yield, preventing the deposition of colored material to the wall of the light source side, without lowering the rate of reaction, by dispersing sodium sulfite in a saturated hydrocarbon, and carrying out the photo-sulfoxylation reaction in the absence of water.
    CONSTITUTION: The objective compound can be produced by adding sodium sulfite to a saturated hydrocarbon (e.g. 8W24C n-paraffin), and reacting sulfur dioxide with oxygen under the radiation of light having a wavelength of ≤500nm using a high-pressure mercury lamp or low-pressure mercury lamp, etc. essentially in the absence of water, at -20W+200°C and 0W50atm. The amount of sodium sulfite is 0.1W10wt% based on the saturated hydrocarbon.
    USE: Useful as a raw material of an alkanesulfonic acid salt which is a surfactant for synthetic detergent, etc.
