Summary, etc. |
<p style="text-align: justify;">Bimolecular reactions of O,O-diethyl-O-<em>p</em>-nitrophenylphosphate (paraoxon) and O,O-diethyl-O-<em>p</em>-itrophenyl phosphorothioate (parathion) with oximate (pyridinealdoxime 2-PyOx<sup>-</sup> and 4-PyOx<sup>-</sup>) and its functionalized oximate, 4-(hydroxyimino)methyl)-1-alkylpyridinium bromide ions (alkyl = C<sub>10</sub>H<sub>21 </sub>(4- <sub>10</sub>PyOx<sup>-</sup>); alkyl = C<sub>12</sub>H<sub>25</sub> (4-C<sub>12</sub>PyOx<sup>-</sup>)) have been investigated in aqueous and cationic micellar media of cetylpyridinium bromide, cetyltrimethyl-ammonium bromide and cetyltetradecyltrimethylammonium bromide at <em>p</em>H 9.5 and 27 <sup>o</sup>C. Under the micellized condition, a 1.2×10<sup>3</sup> fold and 9.0×10<sup>6</sup> fold rate enhancement over the aqueous reaction of paraoxon (<em>k</em><sub>o</sub> = 7.5×10<sup>-8</sup>s<sup>-1</sup>) and parathion (<em>k</em><sub>o</sub> = 9.5×10<sup>-11</sup>) is observed.</p> |
