WebThis is prompting the search for “green” (i.e., environmentally friendly) alternatives to xanthate (Dong and Xu, 2011 ). Dithiophosphates are the second most common thiol collectors and their use dates back to 1920 ( Crozier 1991; Adkins and Pearse, 1992 ). An example structure is given in Figure 12.7 (b). WebDCM, vinyl oxetane (1 mmol), and O,O-diisopropyl dithiophosphoric acid (1.2 mmol, 1.2 eq.). The reaction was stirred at room temperature and monitored by TLC till all of oxetane was consumed. DCM was then removed under reduced pressure and the crude residue was purified by flash chromatography to afford the corresponding alcohol product.

It is the processor for production of the organothiophosphate insecticide Malathion. Although samples can appear dark, the compound is a colorless, distillable liquid. It is prepared by treating phosphorus pentasulfide with methanol: Diethyl- and dimethyl dithiophosphoric acids react with bases. The results of this neutralization reaction are salts, e.g., ammonium diethyl dithiophosphate. Diethyl dithiophosphoric acid reacts with zinc oxide to give zinc dithiophosphate, which is used as an oil additive: ZnO + 2 (C2H5O)2PS2H → [(C2H5O)2PS2]2Zn + H2O
