Diphenyl sulfone is widely used as a high-temperature solvent in various industrial processes, particularly in the production of polymers like polyethersulfone (PES) and polysulfone. Its thermal stability makes it ideal for applications requiring elevated temperatures, such as in the synthesis of high-performance plastics. Additionally, it serves as an intermediate in the manufacture of dyes, pharmaceuticals, and agrochemicals, contributing to the development of products like herbicides and insecticides. In the electronics industry, diphenyl sulfone is utilized in the production of heat-resistant materials for circuit boards and other components. Its ability to withstand harsh conditions also makes it suitable for use in coatings and adhesives that require durability and resistance to degradation.
