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.

Abstract: A phosphor excitable by X-ray and blue-light emits light in the near-infrared (NIR-II, 1000-1700 nanometers) forms nanoparticles less than 200 nanometers diameter. The nanoparticles are tagged by coating with silica, then conjugating with polyethylene glycol (PEG) and tissue-selective compounds such as antibodies, nucleic acid chains, and other ligands. In embodiments, we administer the tagged nanoparticles to a subject, then localize the nanoparticles, and thus antigen-bearing tissues, by irradiating the subject with X-ray or other radiation beams while imaging near infrared light emitted from the subject. The nanoparticles are made by mixing 1-50 micron calcium oxide and germanium oxide powders with dilute nitric acid, adding chromium (III) nitrate at a ratio to germanium between 0.001 and 0.1, adding tartaric acid solution with molar ratio to metal ions between 1-10, and adjusting pH to 0.1-4 with nitric acid, then later heating to form a sol, oven drying, and calcinating the sol.
