Ammonium butyl phosphorodithioate

Ammonium butyl phosphorodithioate (CAS 1071-18-7), also known as O,O-dibutyl phosphorodithioate ammonium salt, is a sulfur- and phosphorus-bearing organosalt used as a functional additive.

It acts as both a corrosion inhibitor and an extreme-pressure lubricant component, protecting metal surfaces under demanding operating conditions in mineral processing and lubrication systems.

In mining and mineral processing, it functions as a flotation collector or depressant aid, improving selective separation of sulfide ores during the extraction process.

Lubricant formulators incorporate it into metalworking fluids and gear oils where its phosphorodithioate chemistry delivers anti-wear and extreme-pressure performance on metal contacts.

It is also used in hydraulic fluid formulations where corrosion protection of metal components is a primary performance requirement for industrial maintenance fluids.

Targeting copper alloy and steel systems, this chemical benefits from its dual corrosion-inhibiting and lubrication functionality across various heavy-duty industrial applications.

Ammonium butyl phosphorodithioate is typically supplied as a liquid or solution, suited for direct blending into oil- or water-based formulations for manufacturing.

It is available in technical grade for industrial applications. Bulk supply in drums or intermediate bulk containers (IBCs) is standard for industrial procurement volumes.
