      -----The application of trimethoyl chloride(TMC) in the synthesis of polymer materials and membrane technology
      2024-11-06         
      Main Applications

      1. Preparation of Polyamide Membranes
      Terephthaloyl chloride is an important chemical raw material widely used in the production of polyamide reverse osmosis membranes. These membranes have significant applications in seawater desalination, high-purity water treatment, and gas separation. With advancements in polymer chemistry and materials science, the demand for Terephthaloyl chloride has been increasing, making it a research hotspot.

      2. Organic Solvent Nanofiltration (OSN) Technology
      Organic solvent nanofiltration is an emerging separation technology that effectively separates small molecular solutes. Research has shown that by using metal ions as catalysts, ultra-thin polyamide separation layers can be synthesized on polymer-based membranes, significantly improving membrane permeability and selectivity. For instance, one study successfully prepared high-performance composite membranes using Terephthaloyl chloride as a monomer in interfacial polymerization, achieving a high rejection rate (>99%) for solutes larger than 500 Da and quadrupling the permeability compared to membranes without added metal ions.

      Research Progress
      In recent years, research on Terephthaloyl chloride has deepened, particularly in membrane materials and separation technologies. For example, introducing transition metal ions to modulate interfacial polymerization can effectively control the thickness of polyamide membranes, optimizing their performance. This approach not only enhances membrane permeability but also improves their resistance to organic solvents and long-term stability.

      In summary, Terephthaloyl chloride has enormous potential in the chemical industry, and advancements in related technologies will further promote progress in fields such as water treatment and gas separation.
