A supramolecular catalyst of Pd/β-cyclodextrin thin film is synthesized via a facile and one-pot procedure at an oil-water interface. Macrocyclic oligosaccharides of cyclodextrins with glucose units have a wide range of applications due to their hydrophobic and chiral interior. Due to the ability of this supramolecular catalyst to form inclusion complexes with small organic molecules, the as-synthesized catalyst was applied for the reduction of toxic nitroaromatic compounds (p, o, m-nitrophenol and 4-Cl-2-nitrophenol) and the degradation of harmful azo dyes (methyl orange and bismarck brown) with considerable results. This investigation illustrates the change of the catalyst properties in the presence of molecular receptors attached to the catalyst surface.

Paragraph 0043; 0044, (2017/04/08)
The invention belongs to the technical field of a chemical industry, and particularly relates to a novel technology for preparing ortho-aminophenol. By adopting the novel technology for preparing the ortho-aminophenol disclosed by the invention, more 1.1-1.2 tons of elemental sulfur and 2 tons of sodium sulfate solid can be recovered from per 1 ton of ortho-aminophenol, a hydrogen sulfide gas can be obtained after acidification, sodium hydrosulfide is generated by virtue of an absorption tower to put into reproduction, 3-4% of solid waste can be obtained by using four-effect evaporation, and can be put into reproduction, the traditional technology can be used for purifying just by rectification, and the purity of the ortho-aminophenol can be improved by distillation firstly, so that the energy source and equipment are saved, the wastewater generated in the production process can be recycled, finally, wastewater is hardly generated, and impurities are also discharged and recycled in the process.
