The invention relates to a method for producing IPPP (Isopropyl Phenyl diphenyl Phosphate) 50. The method comprises the following steps of: (1) esterification: adding alkylphenol into an esterification kettle containing a calcium-magnesium catalyst, pumping phosphorus oxychloride into the kettle when the temperature is below 50 DEG C, stirring, and starting up a normal-pressure acid discharging system, and obtaining qualified crude ester when the final acid value is smaller than 4 mgKOH/g; and (2) distillation: pumping the qualified crude ester into a distillation pot, and carrying out heating, reduced-pressure distillation, separation and purification;, and taking distillates, obtained at the temperature of 270 DEG C, as finished products, thereby completing the distillation. According to the method, in order to increase the production efficiency and decrease energy consumption, the raw material ratio is adjusted, a phosphorus oxychloride excess method is adopted, and the optimal mole ratio of phosphorus oxychloride to alkylphenol is (1: 3.0) to (1: 5.0); and under the conditions, alkylphenol is enabled to fully react with phosphorus oxychloride, and HCl is completely diluted into industrial hydrochloric acid by a falling-film absorption tower, so that the pollution to environments cannot be caused.
