The invention discloses an acylphosphine efficient photoinitiator and a preparation method thereof. The preparation method comprises the following steps of firstly in a solvent and in the presence of a catalyst, reacting organic phosphorus halide as a raw material with an alloy of active metal; reacting reaction product obtained from the former step with an aliphatic alcohol compound containing active hydrogen to product a phosphine hydride compound; reacting the phosphine hydride compound with acyl halide to obtain an acylphosphine compound; after the reaction is completed and under the condition of no separation, further adding an oxidant into a reaction container to prepare acylphosphine oxide. By the preparation method of the acylphosphine efficient photoinitiator designed by the invention, the separation of an intermediate is not needed, the yield and production efficiency of the product are increased and the needs of industrial production can be met.
