An indirect electrochemical preparation of 2,5-dimethoxy-2,5-dihydrofuran from furan in a packed bed electrochemical reactor was described. The experimental results showed that the current efficiency was more than 90%, the product yield was more than 90% and the electric energy consumption was less than 3.0kwh/kg product under the optimized operating conditions such as 0°C [similar to] 5°C reaction temperature, 4.0V [similar to] 6.0V electrolysis voltage and more than 2000A/m2 operating current density.
