Reactions of PO(x)Cl(y)-ions with O(2)(a1-delta-g), H(2)O, and Cl(2) at 298 K
Abstract
The rate constants and product branching ratios for the reactions of phosphorus oxychloride anions, POxCly" for x = 1-2 and y = 1-3, with 02(a'Ag), C12 and H20 have been measured in a selected ion flow tube (SIFT) at 298 K. A mixture of 02(a'Ag) in 02 has been produced using a recently designed chemical singlet oxygen generator (sparger) with an emission detection scheme adopted previously in our laboratory. The experiments continue a series of investigations into the oxidation reactions of POxCly~ ions, searching for pathways to the terminal P02" and PCV ions observed in combustion chemistry with POCl3 present. None of the POxCly" ions react with H20 or 02(a'Ag). The 02(a(1)Delta(g)) rate constants have a limit of <1 x 10-11 cm(3) s(-1), except for P02CI" where a limit of <5 x 10-11 cm(3) s(-1) has been determined. The H20 rate constants have limits of <1 x 10-11 cm(3) s(-1). All of the POxCly" ions react with C12, excluding P03 and PO(x)C1(y). Depending on the reactant ion. CI, Cl(2) or PO(2)C1(2) product ions form.
