1, Dow ion exchange resin is in great demand in the field of water treatment, accounting for about 90% of the output of ion exchange resin, which is used to remove all kinds of anions and cations in water. At present, the largest consumption of ion exchange resin is pure water treatment for thermal power plants, followed by atomic energy, semiconductor and electronics industries.
2. Ion exchange resin in food industry can be used in industrial devices such as sugar making, monosodium glutamate, wine making and biological products. For example, high-fructose syrup is to extract starch from corn, then hydrolyze it to produce glucose and fructose, and then carry out ion exchange to produce high-fructose syrup. The consumption of ion exchange resin in food industry is second only to water treatment.
3. Ion exchange resin in pharmaceutical industry plays an important role in developing a new generation of antibiotics and improving the quality of original antibiotics. The successful development of streptomycin is a prominent example. In recent years, it has also been studied in the Chinese Medicine Committee.
4. Synthetic chemistry and petrochemical industry
In organic synthesis, acids and bases are often used as catalysts for esterification, hydrolysis, transesterification and hydration. It is also more advantageous to use ion exchange resin instead of inorganic acid and alkali to carry out the above reaction. For example, the resin can be reused, the product is easy to separate, the reactor will not be corroded, the environment will not be polluted, and the reaction is easy to control.
