It is a kind of acid phosphorous-type extracting agent,widely used as extracting agent for non-ferrous and rare earth metals.
AD290 has proven to be an excellent extractant for the separation of cobalt from nickel from both sulfate and chloride media.
(1) It is now chiefly used as a processing solvent,instead of hydroterpineol,for producing hydrogen peroxide by anthraquinone process. It is an ideal solvent in this process,for its low volatility and good extraction distribution coefficient.(2) It is also a cold-resisting and fire-retarding plasticizer applied in ethylenic and cellulosic resins,synthetic rubbers. The cold resisting property is superior to adipate esters.
It is mainly used as extracting agent for rare earth metals such as uranium, thorium, vanadium; widely used as defoaming agent in dyes, coating, petroleum drilling, paper making industry; also used as plasticizer and chemical reagent.
The product is widely used in printing and dyeing, ink, building, oilfield and other fields as defoaming agent and penetrant.
