Abstract:
Xanthates are a class of important organic compounds that are widely used in fields such as mineral processing, environmental protection, and chemical synthesis. This paper systematically introduces the structures, physicochemical properties, and product design strategies of xanthates, and deeply explores the application of molecular structural assembly, quantum chemical calculations, and quantitative structure−activity relationship studies in the development of novel xanthates. It also analyzes pathways for optimizing reagent performance through mixing xanthates and the combined use of reagents. The paper mainly elaborates on the direct synthesis method and the solvent method for xanthate synthesis, and summarizes the process principles, advantages, and disadvantages of other methods. It provides an overview of the applications of xanthates in flotation, wastewater treatment, and synthesis of fine chemicals. It also introduces various technologies for treating xanthate wastewater, including chemical precipitation, adsorption, chemical oxidation, microbiological methods, and combined treatment methods. In addition, this paper offers a perspective on the development and application direction of xanthates.
