Application scenarios
1. 🚀 As a core monomer for polymer materials:
• Polyester materials: Polyethylene furandicarboxylate (PEF), polymerized with ethylene glycol, is a current research hotspot. PEF surpasses traditional petroleum-based polyester PET in gas barrier properties (such as oxygen and carbon dioxide) and thermodynamic performance, making it ideal for manufacturing high-performance packaging materials such as beverage bottles and food films, effectively extending shelf life.
• Polyamides: It can be used to synthesize novel bio-based polyamides (commonly known as nylon). These materials typically possess excellent thermal stability and mechanical properties and can be used in fields such as engineering plastics. Its derivative, tetrahydrofuran-2,5-dicarboxylic acid (THFDCA), can be used to synthesize polyamides with high water absorption.
• Other polymers: FDCA can also be used to synthesize polyurethanes, unsaturated resins, and as a plasticizer. Its flexible derivative, THFDCA, can replace petroleum-based raw materials in the manufacture of thermoplastic polyesters and elastomers, with potential applications in automotive, protective equipment, and clothing industries.
2. 🧪 Applications in the pharmaceutical field:
FDCA is a key raw material for synthesizing intermediates of certain antibacterial drugs. Furthermore, it is itself listed as an “endogenous human metabolite,” giving it value in pharmaceutical research.
3. ✨ Other cutting-edge and potential applications:
• Metal-organic frameworks (MOFs): FDCA can be used as an organic linker to synthesize MOF materials with specific pore structures. These materials have applications in gas adsorption, separation, and catalysis.
• High-performance fibers: FDCA is a potential monomer for the preparation of high-performance fibers such as aramid fibers.

Why are powdered catalysts rarely used in chemical reactions?
1, Mass transfer limitation: Powder catalysts usually have a large surface area and pore structure, which is designed to increase the activity of catalytic reactions. However, reactant molecules may encounter mass-transfer limitations during their entry into these pores, resulting in a limited reaction rate. In contrast, the use of catalysts with other morphologies (e.g., granular or porous) can alleviate the mass transfer limitations and thus increase the reaction rate.
2, Pressure Drop Problem: Powdered catalysts typically form a tightly packed bed in the reactor. As the reaction proceeds, the reactants pass through the catalyst layer, which can result in a large pressure drop. This pressure drop increases the operating cost of the system and may require catalyst maintenance and replacement after a long period of operation.
3, Dispersion: Powdered catalysts are poorly dispersed in the reactor due to their granular form. Poor dispersion may lead to under-utilisation of some of the catalyst particles, thus affecting the efficiency and product selectivity of the reaction.
4, Reaction thermal management: Some catalytic reactions are exothermic, and the use of powdered catalysts may lead to heat accumulation in the catalyst bed, making thermal management of the reaction more difficult. This can lead to hot spot formation and reaction temperature control problems.
However, not all situations are unsuitable for the use of powdered catalysts. Under some specific reaction conditions, powdered catalysts may still be a suitable choice. The selection of the appropriate catalyst form depends on the specific type of reaction, the reaction conditions and the requirements for reaction rate, selectivity and mass transfer. In practice, chemical engineers will consider the above factors to select the most suitable catalyst form.
