Embodiment 1
[0026] See figure 1 In the shown internal immersion upward bubbling photochemical reactor, a clamp made of glass that can filter out light with a wavelength shorter than 300nm is arranged in an internal immersion photoreactor 1 made of high borosilicate glass. A jacketed sinker 2, a high-pressure mercury lamp 3 of 500 watts or 1 kilowatt is installed in the jacketed sinker, and the jacket is provided with an inlet and outlet for cooling water; The bottom of the type photoreactor communicates with a pipeline with a gas-liquid mixing valve 4, a gas inlet 5 is arranged on the pipeline above the gas-liquid mixing valve, and the gas inlet 5 is arranged below the gas-liquid mixing valve. The inlet 6 of the reaction solution is arranged on the pipeline; the outlet 7 of the reaction solution is arranged above the said in-immersion photoreactor.
[0027] The photochemical synthesis of monochloroethylene carbonate is carried out by using the above-mentioned internal immersion upward bu...
Embodiment 2
[0039] The photochemical synthesis of monochloroethylene carbonate was carried out using the internal immersion upward bubbling photochemical reactor of Example 1.
[0040] The solid ethylene carbonate of 176g is directly heated and melted, and the liquid ethylene carbonate is pumped into the described inner immersion upward bubbling photochemical reactor from the inlet of the reaction solution of the inner immersion upward bubbling photochemical reactor In the in-immersion photoreactor, feed nitrogen into the described liquid ethylene carbonate in the in-in-immersion photoreactor from the gas inlet, then open the chlorine valve, with the flow rate of 3g / min, by The gas inlet feeds chlorine gas into the liquid ethylene carbonate in the immersion photoreactor, adjusts the flow of nitrogen to make the bubbling uniform; The 500-watt high-pressure mercury lamp in the jacketed sinker in the liquid ethylene carbonate carries out photochemical chlorination reaction, and the temperatu...
