SODIUM DI(ISOBUTYL)DITHIOPHOSPHINATE Chemical Properties,Usage,Production

Chemical Properties

Yellowish liquid odorless

Uses

Sodium Di(Isobutyl)Dithiophosphinate (DTPI) is a dithiophosphate collector, mostly used in ore flotation. The adsorption of DTPI on the pyrite surface relies on chemical mechanisms rather than electrochemical interactions^[1].

Flammability and Explosibility

Not classified
