The invention relates to the field of photocuring functional new material chemicals, and discloses a high performance liquid phase streamline type continuous automatic production technology of an acylphosphine oxide organic phosphine compound for the first time, which not only can produce a single specific target product, but also can co-produce a product mixture of two or more than two of the products of the type. The process technology has outstanding low-cost economic competitiveness and environment-friendly characteristics for large-scale manufacturing of target products. The target product comprises sym-trimethylbenzoyl diphenyl phosphine oxide (also known as 2, 4, 6-trimethylbenzoyl diphenyl phosphine oxide, trade name TPO), sym-trimethylbenzoyl phenyl ethyl phosphonate (trade name TPO-L) and structural analogues thereof, and a mixture of the sym-trimethylbenzoyl diphenyl phosphine oxide and the sym-trimethylbenzoyl phenyl ethyl phosphonate. The organic phosphine compound is an olefinic bond-containing (C=C) unsaturated radiation polymerization system photoinitiator and/or flame retardant and the like with wide application.
