The invention discloses a process for continuously synthesizing prochloraz and an intermediate acylate of a prochloraz active compound, and relates to the technical field of pesticide chemical engineering. The prochloraz comprises the following raw materials in parts by weight: 100 parts of 2,4, 6-trichlorophenol, 70-90 parts of liquid alkali, 150-190 parts of dichloroethane, 2-5 parts of imidazole, 120-180 parts of propylamine, 25-50 parts of caustic soda flakes, 3-5 parts of an antioxidant, 2-3 parts of a catalyst, 3-5 parts of a stabilizer, 200-250 parts of toluene, 35-45 parts of triethylamine, 180-230 parts of an extraction agent and 120-150 parts of trichloromethyl carbonate. The amination reaction time is shortened, the amination reaction yield is improved, the reaction time is substantially shortened; the conversion rate of the raw materials reaches 98% or above, the yield of the product reaches up to 96%, the purity of the product is improved; the catalyst can be repeatedly used after being soaked in ethanol, the cost is saved; and the process is safe and environment-friendly, is greatly superior to the preparation process in the prior art and is very suitable for large-scale industrial production.
