Description

Ethylhexadecyldimethylammonium 2-tert-Butylphenolate is a quaternary ammonium salt-based compound, specifically a cationic surfactant and phase-transfer catalyst. This product is valued for its dual functionality, combining the properties of a long-chain ammonium cation with a sterically hindered phenolic anion. It is primarily sought by industries requiring specialized catalysts for organic synthesis or as a functional additive in material science. Key applications include its use in polymerization reactions, as a corrosion inhibitor, and in the formulation of specialty coatings and biocides.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in alkylation, esterification, and polymerization processes.
• Polymerization Aid: Acts as a catalyst or stabilizer in the production of specific polymers and resins.
• Corrosion Inhibitor: Used in formulations for industrial lubricants, fuels, and metalworking fluids to protect ferrous and non-ferrous metals.
• Biocide / Preservative: Employed in the formulation of disinfectants, algicides, and wood preservatives due to its quaternary ammonium structure.
• Surfactant & Emulsifier: Serves as a cationic surfactant in specialty cleaning formulations, textile processing, and agrochemical emulsions.
• Electronics & Material Science: Used as a surface modifier or additive in the production of advanced materials and electronic chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
