1. Fluororubber vulcanization accelerator
Core application: in combination with bisphenol AF, as an accelerator for crosslinking of fluororubber (addition amount 0.5%–0.7%), significantly improving the compression deformation, chemical corrosion resistance and thermal stability of rubber.
Industrial case: Benzyltriphenylphosphonium Chloride used for crosslinking of tubular halloysite/fluoroelastomer nanocomposites to optimize processing performance.
2. Organic synthesis catalyst
Wittig reaction: key ylide precursor for synthesizing fine chemicals such as trans-stilbene, cinnamate, and light-driven molecular brake (pentatriene).
Phase transfer catalysis: promotes alkylation, polymerization and other reactions, suitable for the synthesis of pharmaceutical intermediates (such as non-chiral hydroxyformamide inhibitors) and liquid crystal monomers.
3. Polymer material additives
Curing accelerator: Benzyltriphenylphosphonium Chloride accelerates the curing process of epoxy resins and powder coatings.
Asphaltene modification: Benzyltriphenylphosphonium Chloride participates in the formation of the “island structure” of petroleum asphaltene to improve material properties
