Novel condensation reaction method of dibenzoylmethane

The invention provides a novel condensation reaction method of dibenzoylmethane, relates to the technical field of chemical synthesis, solves the problem of safety risk caused by sodium methoxide used in the existing condensation reaction process of dibenzoylmethane, and comprises the following steps: S1, taking xylene and methanol as raw materials, and adding 2000-4000 L of xylene into a reaction kettle; the method comprises the following steps: adding 120-150Kg of methanol into a high-level metering tank, adding sodium hydroxide again, carrying out heat-preservation reaction for 1 hour under heating reflux of steam at 70-80 DEG C, heating to 130 DEG C after the heat-preservation reaction is finished, dropwise adding industrial methanol with different contents into the high-level metering tank, and carrying out distillation treatment in the dropwise adding process; s2, after distillation treatment is completed, the temperature is reduced to 30-80 DEG C, methyl benzoate is added, the temperature is increased
