Patent ID: 7875739

Claim:
A method for decomposing an organophosphorus compound comprising subjecting said organophosphorus compound to an alcoholysis reaction in a medium comprising non-radioactive metal ions selected from the group consisting of lanthanide series metal ions, transition metal ions, and combinations thereof, and at least a trace amount of alkoxide ions, wherein said organophosphorus compound has the following formula (10): where: J is O or S; X, G, Z are the same or different and are selected from the group consisting of Q, OQ, QA, A, OA, F, CI, Br, I, QS, SQ, SA, and C≡N; Q is a substituted or unsubstituted branched, straight-chain or cyclic alkyl group having 1-100 carbon atoms; and A is a substituted or unsubstituted aryl group selected from the group consisting of phenyl, biphenyl, benzyl, pyridyl, naphthyl, polynuclear aromatic, and aromatic heterocyclic, or a substituted or unsubstituted non-aromatic heterocyclic group; wherein, when X, G, Z are the same, X, G, Z are selected from the group consisting of OQ, OA, F, Cl, Br, I, QS, SQ, SA, and C≡N; and wherein said substituents are selected from the group consisting of Cl, Br, I, F, nitro, nitroso, Q, alkenyl, OQ, carboxyalkyl, acyl, SO 3 H, SO 3 Q, S═O(Q), S(═O) 2 Q, amino, alkylamino (NHQ), arylamino (NHA), alkylarylamino, dialkylamino, and diarylamino; wherein, through said alcoholysis reaction, said organophosphorus compound is decomposed.
