A method for the preparation of salicylamide, in a 1000-litre stainless steel reactor, 150 kg of methyl salicylate, 420 kg of toluene were added, heated to 40-45 ℃, ammonia was continuously passed through the ammonia reaction, the reaction temperature was controlled at 40-45 ℃, and the reaction pressure was controlled at 0.25-0.35 MPa, and the passage of ammonia was stopped after the ammonia reaction for 5 hours, and then the toluene and the reaction was heated up and recovered. Then toluene and methanol, a by-product of the reaction, were heated and recovered, and the remaining material was cooled down to 20 ℃, and salicylamide was obtained after crystallisation and centrifugation, with a yield of 97.8%.
