Embodiment 1
[0338] Formation of one or more organic compounds from unsaturated hydrocarbons
[0339] Formation of EDC from ethylene using copper chloride
[0340] This experiment involves the formation of ethylene dichloride (EDC) from ethylene using copper chloride. The experiment was carried out in a pressure vessel. The pressure vessel contained an outer jacket containing the catalyst (ie, copper chloride solution) and an inlet for ethylene gas sparging in the copper chloride solution. The concentrations of the reactants are shown in Table 1 below. In the experiment, the pressure vessel was heated to 160° C., and ethylene gas was passed into the vessel containing 200 mL of the solution at 300 psi for 30 minutes to 1 hour. Cool the container to 4°C before venting and opening. The product formed in solution was extracted with ethyl acetate and then separated using a separatory funnel. Gas chromatography (GC) was performed on the ethyl acetate extract containing EDC.

[0346] electrochemical reaction
[0347] This example illustrates the electrochemical reaction when using a corrugated anode and a PK membrane in an electrochemical cell. 40cm 2 The cell configuration on the active area laboratory cell is a Ti-base corrugated plate bridged with a coated Ti mesh anode (Ti-basecorrugation), a Ni flynet meshed cathode with a platinum group metal catalyst coating , FAA-3-PK-30 anion exchange membrane (FuMA-Tech) and N2030 cation exchange membrane (Dupont). The cell condition is composed of 4.5M CuCl 2 , 1.5M CuCl, 2.5M NaCl, 300g / NaCl brine feed composition pH 2 anolyte, and 30 wt% sodium hydroxide catholyte. The operating temperature of the battery is 90°C. The running time of the electrochemical reaction was 30 min. These conditions at 3kA / m 2 At a battery voltage of 2.35V, CuCl to CuCl 2 transformation.

[0353] For Cu(I) and Cu(II), the starting materials are CuCl and CuCl, respectively 2 . The components are then oxidized in a parallel high throughput reactor system. The reaction atmosphere was clean dry air at a pressure of 250 psig, and the reaction temperature was about 160°C. The reaction time is 30min or 60min. After the reaction was complete, the reaction contents were cooled to ambient temperature and the resulting s...
