Chemistry of phosphorus fluorides. Part III. The reaction of thiophosphoryl-fluoride with dimethylamine and some properties of the dimethylaminothio- phosphoryl fluorides

Abstract

Di~ncthylamine reacts with thiophosphoryl fluoride with non-integral stoichiometry to yield the volatile conlpound dimethylaminothiophosphoryldifluoride and the solid products contained hexafluorophosphate and difluorodithiophosphate ions, and an unstablc complex ion containing phosphorus and fluorine. Thc reaction of dimethylaminotl~iophosphoryldifluoride with dimethylamine to form bis-(dimethyla~nino)thiophosphorylfluoride has also been studied. The solid residues of this reaction contained hexafluorophosphate and difluorodithiophosphate ions and an unidentified phosphorus-fluoride salt. Din~ethyla~ninothiopl~osphoryldifluoride did not complex with boron trifluoride but reacted with hydrogen halides to yield the halogenothiophosphoryldifluorides. Physical and spectroscopic data on the alkylan~inothiopl~osphoryl fluorides are reported.

A simple methodology for the quantification of graphite in end-of-life lithium-ion batteries using thermogravimetric analysis

“…At this temperature, MS detected the production of water, traces of EC, other organic species such as diethyl carbonate (DEC), polycarbonate (PC) (See Table S1 in supplementary information for detailed information of m/z current ions), and phosphoryl fluoride (POF 3 ) (m/z = 48, 64, and 86). POF 3 is a known product of the chemical reaction between LiPF 6 and H 2 O ( Equation 9 ) 49 : …”

“…From a safety perspective, POF 3 and HF are of special interest since they are hazardous and corrosive. 49 Thus, it is advised to consider these reactions whenever thermal processing of battery waste is planned.…”
