| titleOfInvention | PROCEDURE TO STABILIZE A PESTICIDE PHOSPHORIC ESTER. |
| abstract | Procedure for stabilizing a pesticidal phosphoric ester, the molecule of which has at least one alkyl radical containing from one to three carbon atoms, optionally mixed with a phosphoric ester solvent, a solvent that is solid or liquid at room temperature with or without pressure and/or optionally in admixture with one or more adjuvants compatible with the phosphoric ester, of which at least one is chosen from among the oxiranes, the aforementioned procedure being characterized in that it is added to the phosphoric ester or to the mixture containing it from 0, 1 to 10 calculated on the weight of the phosphoric ester, of an agent capable of stabilizing said ester against protonization and consisting of at least one diacene defined by one of the following limit formulas: **(See formula)** in which, R represents an aryl radical containing one, two or three aromatic rings, of five or six members each, condensed or linked together by a direct bond or by an oxygen atom or by an NH, CH2, or CH = CH group, (a) one of the rings may optionally comprise, among its members, one or two heteroatoms chosen from nitrogen, oxygen and sulfur; (b) two or four of the carbon atoms of one of the rings may be saturated, when the aryl radical contains several condensed rings; (c) being able to carry one or two rings, optionally, a phenylazo or naphthylazo or arylazoarylazo group, in which each of the aryl radicals is chosen between the phenyl and naphthyl radicals; (d) one or two rings may optionally carry a metallizable group chosen from the hydroxy, carboxy, amino, monoalkylamino groups, containing from one to four carbon atoms, phenylamino, phenylsulfamido and alkylsulfamido containing from one to four carbon atoms; (e) each ring may optionally carry from one to four substituents chosen from fluorine, chlorine, bromine, iodine, carbonyl oxygen, alkyl radicals containing from one to six carbon atoms, the alkenyl radicals containing from two to five carbon atoms, cycloalkyl radicals containing from five to six carbon atoms, alkanoylamino radicals containing from one to five carbon atoms, alkoxy radicals containing from one to five carbon atoms, benzyloxy radicals, nitro, sulfo, cyano, sulfamoyl groups, dialkylamino groups containing, in total, two to eight carbon atoms, alkoxycarbonyl groups containing two to six carbon atoms, alkylsulfonyl groups containing one to five carbon atoms, the sulphamoyl groups whose nitrogen atom carries one or two hydrocarbon radicals containing, in total, one to eight carbon atoms, the gr alkanoyloxy and alkenoyloxy compounds containing not more than eighteen carbon atoms, alkanoyl radicals containing from one to five carbon atoms, dialkylaminoalkoxy radicals containing, in total, three to nine carbon atoms; R'and R''are the same or different and each represent a benzyl radical or an alkyl radical containing from one to seventeen carbon atoms or an alkenyl radical containing from two to eight carbon atoms or a low-falling aryl radical the definition given above for R, one of which may also be a phenylazo or naphthylazo radical; R'and R''may also together form a bivalent straight or branched chain hydrocarbon group containing in total four to fourteen carbon atoms or together with the carbon atom C form a hydroaryl radical derived from R, as defined above, the said radical then carrying, in addition to the optional substituents indicated above, an oxygen atom that forms a member -CO- or an imine group that forms a member-C (= NH) - or-C (= NX) - in which X represents an alkyl radical containing from one to five carbon atoms or a phenyl radical; and the grouping (see formula) represents an aryl radical that falls under the definition given above for R, said diacene being soluble in the phosphoric ester and/or in said solvent.
