Molten salts are substances whose melting point is lower than at least one of the compounds constituents. The advantages of using molten salts rather than traditional refining agents include: 1) cost reduction due to the reduced need for raw materials and improved efficiency; 2) better safety for handling and storage; and 3) a higher quality product due to the elimination of dust and other contaminants.
Molten salts have a long history of being used in chemical processing, and are increasingly being used to produce and purify a variety of industrial products. For example, in producing plastics, molten salts are used to separate and purify thermoplastics, while in synthetic rubber production, they are used to dissolve and remove impurities. In the production of paints, varnishes and other materials, molten salts are used to separate and purify the chemicals in the mixture and to remove excess water or volatile solvents.
Molten salts are also commonly used in the refining of natural resources, such as coal, oils, and metals. Metal refining often involves dissolving metals in molten salt baths; this allows different metals to be separated from one another, as well as from other impurities. In oil production, molten salt baths are frequently used to purify the crude oil, removing impurities and improving the quality of the final product.
Apart from its refining potential, molten salts also have some unique characteristics that make them ideal for certain types of applications. For example, some molten salts have a very low melting point, which makes them useful for applications where low temperatures are desired. Additionally, certain molten salts are non-toxic, making them safe and suitable for use in food production and other sensitive applications. Furthermore, molten salts can be tailored to specific needs, as they can be finely adjusted in terms of temperature, chemical composition, and physical properties.
Molten salts are increasingly popular in industrial applications, due to their cost-effectiveness, safety, and effectiveness for refining. Their low melting points, non-toxicity, and ability to be fine-tuned for specific applications make them an ideal choice for a wide variety of applications.
