The invention belongs to the technical field of organic synthesis and relates to a preparation method for benzyl phosphonate as a key intermediate of an acyl phosphine oxide type photoinitiator. According to the method, benzene, phosphorus trichloride and alkyl alcohol are taken as main raw materials and are compounded into benzyl phosphonate through two-step reaction. The preparation method is characterized in that a target product is generated through the low-temperature reaction of the dichlorophenyl phosphine and alcohol under the condition of a gemini basic ionic liquid catalyst in the second step reaction, the reaction temperature is controlled within -10 DEG C to 10 DEG C, the dichlorophenyl phosphine is dropwise added and then the mixture reacts for 0.5-7 hours under a stirring condition after the temperature is increased to 30-50 DEG C. The preparation method has the advantages of low cost, simple and convenient after-treatment, high yield, and the like, and is suitable for industrial production.
