Description

Oleyl Dihydrogen Phosphate is a long-chain organophosphorus compound derived from oleyl alcohol. This specialty chemical serves as a versatile intermediate and functional additive, valued for its surfactant and chelating properties. It is primarily utilized in the formulation of industrial lubricants, metalworking fluids, and as a component in specialty polymer and coating systems.

Application

• As an anti-wear and extreme pressure (EP) additive in synthetic and semi-synthetic metalworking fluids and lubricants.
• Functioning as a corrosion inhibitor and coupling agent in industrial and institutional cleaning formulations.
• Used as a specialty surfactant and emulsifier in the production of polymers, resins, and advanced coating systems.
• Employed as a chelating agent and dispersant in water treatment and mineral processing applications.
• Serving as a key intermediate in organic synthesis for the production of more complex phosphate esters and derivatives.
• Potential use as a surface modifier and wetting agent in pigment dispersion and textile processing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible materials.
