The utility model relates to a device for preventing ice blockage of a condenser in m-methoxypropiophenone synthesis, which comprises the condenser and a cold water tank, a refrigerant feed port of the condenser is connected with a discharge port of the cold water tank through a circulating pump, and a refrigerant discharge port of the condenser is connected with a feed port of the cold water tank; the cold water tank is provided with a coil pipe, a feeding port of the coil pipe is connected with the refrigerating fluid feeding tank, and a discharging port of the coil pipe is connected with the refrigerating fluid discharging tank. According to the utility model, the potential safety hazard easily caused by blockage and unsmooth emptying of a pipeline in the condenser due to icing of a water-containing material in the condenser because the temperature is too low because the condenser is directly cooled by using a refrigerating fluid is avoided. Cold water is used as a refrigerant, so that the problem that a w
