DITHIOPHOSPHATES 化学特性,用途語,生産方法
工業用途
Alkyl and aryl dithiophosphoric acids and their alkali salts are widely used as sulfide collectors
known as Aerofloat. In general, the phosphorus compounds used as flotation reagents represent a small number
of known organic phosphorus compounds.
Dialkyl dithiophosphoric acids are produced from the reaction of phosphorus pentasulfide (P2S5) with an alcohol in an inert medium. The reaction by-products include dialkyl sulfide, trialkyl dithiophates and sulfur. The acids are unstable and are converted into alkali metal salts for use as a collector.Like xanthates, dithiophosphates are used exclusively as collectors in flotation of sulfide
ore as a secondary collector with xanthates or alone.
