| titleOfInvention | One-step method for synthesizing of the one kind to (neighbour) hydroxy-phenylformonitrile |
| abstract | The invention discloses one kind to the one-step method for synthesizing of (neighbour) hydroxy-phenylformonitrile, after organic solvent being dissolved in (neighbour) methyl hydroxybenzoate, together with ammonia through pipeline enter equipped with catalyst fixed bed reactors under conditions of 250~550 DEG C of reaction temperature, 0~1.0Mpa of reaction pressure one-step synthesis to (neighbour) hydroxy-phenylformonitrile；Ammonia is 2~10:1 to the mass ratio of (neighbour) methyl hydroxybenzoate, and ammonia, the air speed for entering fixed bed reactors together to (neighbour) methyl hydroxybenzoate are 0.5~5.0h ‑1 ；Catalyst is by active component P 2 O 5 , CuO, SnO and MoO 3 It is mediated with carrier.The method of the present invention is more suitable for continuous production using the production form of fixed bed reactors, avoids cumbersome in the complexity and operation of original intermittent reaction technique, and production capacity is remarkably enhanced；The dosage of ammonia is fewer simultaneously, and excessive ammonia can be used again by recycling after gas-liquid separation, there is further raising in save the cost and environmental protection. |
