  • Publication number: 20250066307
    Abstract: A process for producing high-purity ?-caprolactam includes the following steps: (1) cyclohexanone oxime is subjected to a gas phase Beckmann rearrangement reaction; (2) the reaction product obtained from step (1) is successively subjected to gas-liquid separation, solvent removal, and light impurity removal to produce a crude caprolactam; (3) the crude caprolactam is subjected to crystallization to produce a crystallization product and a crystallization mother liquor; (4) the crystallization mother liquor is subjected to crystallization to produce a crystal slurry. At least a part of the crystal slurry is returned to step (2) and/or step (3). The purification process can obtain high-purity caprolactam through only one crystallization and one mother liquor crystallization without reducing the overall yield of caprolactam.

  • Publication number: 20200181799
    Abstract: A method for preparing a GaN substrate material includes: performing in-situ epitaxy on a Ga2O3 thin film and a GaN thin film in a multifunctional HVPE growth system. First, the Ga2O3 thin film is grown on a substrate such as sapphire by an HVPE-like method, and the Ga2O3 is nitrided in an ammonia gas atmosphere to form a GaN/Ga2O3 composite thin film. Then, a GaN thick film is grown on the GaN/Ga2O3 composite thin film by HVPE to obtain a high-quality GaN thick film material. The Ga2O3 layer is removed by chemical etching to obtain a self-supporting GaN substrate material. Or, the conventional laser lift-off method is used to separate the GaN thick film from the heterogeneous substrate such as the sapphire to obtain a GaN self-supporting substrate material.
