Tributyltetradecylphosphonium chloride, CAS: 81741-28-8

Key Applications:

Phase‑Transfer & Solvent‑Free Catalysis

• Functions as a highly efficient phase‑transfer catalyst for nucleophilic substitutions, alkylations, and condensations in biphasic or solvent‑minimized systems.
• Enhances reaction rates in ionic‑liquid‑like media, enabling greener processing and improved mass transfer.

Surfactant, Emulsifier & Hydrotrope

• Long‑chain phosphonium cation provides strong surface activity, supporting emulsification, dispersion, and wetting in complex formulations.
• Used in oil–water systems, specialty cleaners, and industrial processing aids requiring thermal and chemical robustness.

Antimicrobial & Biocidal Formulations

• Exhibits broad‑spectrum antimicrobial activity, making it suitable for research into disinfectants, coatings, and preservation systems.
• Evaluated in polymeric matrices and surface treatments where durable cationic charge is beneficial.

Polymer Modification & Compatibilization

• Acts as a cationic additive to tune polymer polarity, conductivity, and interfacial behavior.
• Supports dispersion of fillers, nanoparticles, and pigments in hydrophobic matrices.

Electrochemical & Ionic‑Liquid Research

• Serves as a precursor or component in task‑specific ionic liquids, especially those requiring high hydrophobicity and thermal stability.
• Used in studies of ion transport, electrode interfaces, and solvent‑free electrochemical systems.

Extraction, Separation & Phase Behavior Studies

• Effective in liquid–liquid extraction of metal ions and organics due to strong ion‑pairing and hydrophobicity.
• Supports research into solvent structuring, micelle formation, and amphiphilic ionic systems.
