titleOfInvention | A kind of method of being produced phenol by salicylic acid sublimation residue |
abstract | The invention discloses a kind of method that salicylic acid sublimation residue produces phenol, it comprises the following steps: (a) Pintsch process: by salicylic acid sublimation residue temperature be 450 ~ 550 DEG C, vacuum tightness be in the reaction chamber of-0.01 ~-0.06MPa stir, heating, generate crude phenol; B () distilation: the crude phenol of generation being passed into vacuum tightness is in the still kettle of-0.05 ~-0.07MPa, with steam heating, the purification of 0.3 ~ 0.5MPa, cooling, reclaims.The present invention is by carrying out the suitable processing treatment of heating pyrolyze, distilation to salicylic acid sublimation residue, be prepared into the high-purity phenol that can be used as important industrial chemicals, not only successfully solve the problem of a large amount of salicylic acid sublimation residue refuse Appropriate application, and turn waste into wealth, decrease environmental pollution, create higher economic worth. |
