Recovering tungsten from the leach solution of adipic acid (ADA) synthesis by oxidizing cyclohexene over tungsten peroxide catalyst is a problem. Herein, a novel process is explored to recover tungsten and recycle catalyst in this production process. The reaction mother liquor of ADA synthesis was treated with triethylamine, and the tungsten peroxide decomposed to tungsten. The acidification of mother liquor with HNO3 leads to precipitation of tungsten in the form of H2WO4. The component of recovered reagent was characterized by X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. A tungsten recovery of 97% was achieved. The regenerated catalyst was prepared from recovered tungsten. The regenerated catalyst provided a yield of ADA of 94.1%, which is comparable to the 94.5% yield of ADA with fresh catalyst. The effective recovery of tungsten and the excellent performance of regenerated catalyst show that an effective recovery approach has been developed.
