Definitions
- the present invention relates to the decontamination of fragile materials contaminated with toxic agents such as organophosphorus compounds and organosulfur compounds without causing significant degradation of said materials. It relates in particular to a new decontamination agent as well as to a composition and a process for destroying these organophosphorus and / or organosulfur pollutants.
- the invention applies more particularly to the treatment of fragile materials contaminated with organophosphorus compounds, such as organophosphates, amidophosphates, organoamidophosphates, phosphorothionates, phosphonothionates and phosphonoamidothionates used in the field of agriculture as insecticides and pesticides , as well as by organosulfur compounds of the RSR ', R and R' type representing in particular hydrocarbon radicals and halogenated hydrocarbon radicals.
- organophosphorus compounds such as organophosphates, amidophosphates, organoamidophosphates, phosphorothionates, phosphonothionates and phosphonoamidothionates used in the field of agriculture as insecticides and pesticides , as well as by organosulfur compounds of the RSR ', R and R' type representing in particular hydrocarbon radicals and halogenated hydrocarbon radicals.
- organophosphorus compounds such as 0, 0-diethyl-Op-nitrophenyl phosphate (Paraoxon®), O, O-diethyl-Op-nitrophenyl phosphonothioate (Parathion®) and 0.0-diethyl- O- (2-isopropyl-4-methyl-6-pyrimidyl) -phosphorothioate
- toxic organosulfur compounds such as 2, 2'-diethyl sulfide or 2-phenyl-2-chlorodiethyl sulfide are also very aggressive chemical agents whose stability allows them to persist on a ground contaminated for several years, without experiencing a significant decrease in toxicity.
- compositions currently available in the decontamination technique are solutions of sodium hydroxide in aqueous medium or in methylglycol in the presence of amine, or of calcium hypochlorite; however, such solutions are corrosive to fragile materials and in particular light metal alloys.
- nucleophilic compounds are effective products for eliminating toxic agents from the organophosphorus and organosulfur series.
- the hydroxyl anion in a strongly basic medium is capable of neutralizing these toxic agents.
- the efficiency obtained is accompanied by a strong aggressiveness with respect to the materials to be decontaminated.
- Another way is to use, in an environment which is not very basic, or even close to neutrality, peroxygen compounds such as hydrogen peroxide, tert-butyl hydroperoxide, perborates and peracids, because of their properties both nucleophilic and oxidising.
- the various peroxygen compounds are used in solutions containing surfactants of the quaternary ammonium type, improving the contact between the peroxygen reagent and the toxic agent during decontamination.
- the peroxides currently proposed in the decontamination of materials soiled by the various families of toxic agents, in particular Paraoxon® and sulfur compounds, are in the form of aqueous solutions of linear peracids with long carbon chain, pH between 6 and 8, or aqueous solutions based on industrial peracids such as magnesium monoperoxyphthalate or phthalimidoperhexanoic acid, these peracids being, in both cases, associated with surfactants in particular of the ammonium salt type quaternary.
- the first peracids are not commercially available and exhibit poor stability and solubility
- the second peracids, although commercially available, are in solid form at room temperature, have poor stability at high temperature and are not easy to handle for their implementation.
- the present invention therefore firstly relates to the use of an acid chosen from percarboxylic acids C2 to C ⁇ in the decontamination of materials contaminated with organophosphorus and / or organosulfur compounds.
- the percarboxylic acid used is in the form of an anhydrous or substantially anhydrous organic solution of said percarboxylic acid, in particular as it was obtained by reaction of an aqueous solution of hydrogen peroxide with the acid corresponding carboxylic acid miscible with water, in the presence of a catalyst and an organic solvent including optionally that which has enabled continuous elimination by azeotropic distillation of water from the reaction medium.
- anhydrous solutions or substantially anhydrous are water-soluble liquids, which allows easier implementation of decontaminating solutions.
- the preferred percarboxylic acid is perpropionic acid, due to its very high stability.
- the anhydrous or substantially anhydrous organic solution of perpropionic acid which may be used includes perpropionic acid as product, propionic acid as unreacted reagent, ethyl propionate as solvent, hydrogen peroxide as unreacted reagent, sulfuric acid or boric acid as catalyst, and dipicolinic acid as stabilizer of the peracid solution produced.
- the present invention also relates to a composition which can be used for the decontamination of materials soiled with organophosphorus and / or organosulfur compounds, this composition being characterized by the fact that it consists of an aqueous solution based on at least one percarboxylic acid. in Co to C ⁇ .
- the percarboxylic acid (s), in particular perpropionic acid, have advantageously been introduced into said composition in the form of an anhydrous or substantially anhydrous organic solution of said percarboxylic acid, as indicated above.
- the percarboxylic acid (s) are present in the aqueous solution at a concentration for example of 3.78 ⁇ 10 ⁇ 4 to 0.15 mol / l.
- the aqueous solution is buffered at a pH of between 7 and 10, in particular at a pH of between 9 and 10.
- the buffers which can be used are commercial solutions of pH 7 to 10.
- pH 9 is obtained from an aqueous solution containing a mixture of boric acid
- the aqueous decontaminating composition also comprises at least one cationic surfactant.
- the cationic surfactant (s) are advantageously of the quaternary ammonium type, being in particular represented by formula (I): R 1
- R 1 R? and R ⁇ , identical or different, each represent a C ⁇ -C ⁇ alkyl group or a C - ⁇ - C ⁇ hydroxyalkyl group;
- - R represents a benzyl group or a linear or branched C ⁇ -C ⁇ g alkyl group;
- - X represents a halogen or a hydroxyl radical
- R represents a linear C g alkyl group
- X represents a halogen
- surfactants are: - cetyl trimethyl ammonium bromide;
- surfactants are known and, for the most part, commercially available. They can be prepared by the methods described by C.A. Bunton et al.,
- the surfactant (s) are present in the aqueous decontaminating composition, in particular at a rate of 10 to 0.1 mole per liter of composition.
- the present invention also relates to a process for decontaminating materials soiled with organophosphorus and / or organosulfur compounds, characterized in that the composition as defined above is applied to the soiled material, by spraying, spraying or simple washing, or soaking said soiled material in a tank containing the composition as defined above.
- the molar ratio of C2 to C ⁇ percarboxylic acid relative to the pollutant is generally from 5 to 10 for organophosphorus pollutants (hydrolysis to phosphate) or from 3 to 5 for organosulfur pollutants (oxidation to sulfone).
- Contaminated fragile materials include electronic circuits (resin, electronic components, soldering), light alloys, polymers (poly (ethyl methacrylate)), etc. These materials have been polluted by deposition of the toxic on the surface: it is therefore a decontamination in heterogeneous phase.
- the tests carried out show a high efficiency of the compositions of the invention for the decontamination of toxic agents, such as Paraoxon® and 2-phenyl-2 '-chlorodiethyl sulfide.
- composition containing C to C4 percarboxylic acid, in particular perpropionic acid, in combination with the surfactant of the quaternary ammonium type allows practically instantaneous degradation of the toxic organophosphorus and organosulfur compounds.
- the composition has excellent stability over time at high temperatures, unlike conventional compositions based on peracids, and that C to C percarboxylic acid is in the form of a water-soluble liquid, which has an advantage when of the use of the composition and which makes it possible to obtain the degradation of the abovementioned toxic agents, in particular the total degradation of the 2-phenyl-2 '-chlorodiethyl sulfide in its non-toxic sulfone form, which is not the case of the other organic peracids which are only available in solid form and which have a low solubility in the aqueous phase.
- dipicolinic acid which had been prepared according to the method described in French patent application FR-A-2 519 634 but with ethyl propionate as solvent.
- Paraoxon® by perpropionic acid solutions is a quick and effective reaction.
- the destruction rates of Paraoxon® are high and quite remarkable.
- Example 2 The same anhydrous solution of perpropionic acid was used as in Example 1.
- Various aqueous solutions buffered to pH 7 or 9 were prepared from the above-mentioned anhydrous solution alone or with the surfactant chloride.
- cetyl trimethyl ammonium, perpropionic acid being at the concentration of 15 x 10 mole / liter and the surfactant, at the concentration of 10 mole / 1.
- the progress of the chemical destruction reaction of 2-phenyl-2 '-chlorodiethyl sulfide is determined by an analysis by gas chromatography, consisting in taking samples over time, analyzed by chromatography after addition of a mineral reducer (sodium thiosulfate).
- Table 2 indicates that the destruction of 2-phenyl-2 '-chlorodiethyl sulfide by perpropionic acid takes place quickly, thus confirming the exceptional properties of perpropionic acid in the decontamination of toxic agents.
