| titleOfInvention | Method and equipment for efficiently synthesizing adipate crystal from ammonium adipate formation waste liquid |
| abstract | The invention belongs to the field of adipate preparation and discloses a method and equipment for efficiently synthesizing an adipate crystal from ammonium adipate formation waste liquid. The method comprises the steps: filtering to remove solid impurities in the ammonium adipate formation waste liquid; cooling to 0-10 DEG C; dropwise adding strong acid into a low-temperature ammonium adipate solution under stirring; adding an adipate crystal seed with the particle size of 1-10mm when the pH value of the ammonium adipate solution is reduced to 3.0-4.5; starting a pulse microwave generator with the frequency of 30-40MHz and the energy concentration of 0.01-0.1w/cm<2>, and meanwhile, further dropwise adding the strong acid; when the pH value of the solution is up to 0.9-1.2, ending the dropwise adding of the strong acid, reducing the stirring speed, stopping the pulse microwave generator after 15-30min, and preserving the heat for 1-2h; and carrying out suction filtration, washing and drying in vacuum. The method has the advantages of high product yield, relatively uniform crystal shape, size and density, fewer impurities, simple process and relatively remarkable economic and environment-friendly benefits. |
