Definitions
- hexogen cyclotrimethylene trinitramine or RDX
- the present invention mainly proposes an original method that makes it possible to differentiate a standard quality hexogen from a so-called insensitive hexogen.
- This method has many advantages over the differentiation methods known to date (IAD test and NQR and AFM methods presented below).
- RDX cyclotrimethylene trinitramine
- I-RDX ® Insensitive-RDX
- RS-RDX Reduced- Sensitivity RDX
- compositions such as PBXN-109 composed of a RDX / Al / PBHT mixture (RDX / Aluminal / HydroxyTechelic PolyButadiene mixture), produced with this quality of hexogen have a reduced sensitivity to the shock wave, measured using the IAD (Detonation Ability Index, described later in the text); see in particular about this: Lecume, S .; Chabin, P. and Brunet, P. (2001), Two RDX Qualities for PBXN-109 Formulation Sensitivity Comparison, 2001 Insensitive Munitions and Energetic Materials Symposium, Bordeaux.
- IAD Detonation Ability Index
- the so-called insensitive hexogen in solid form, can not be differentiated physicochemically from the standard hexogen.
- the so-called classical physicochemical characterization techniques do not allow a qualitative or quantitative differentiation of the so-called insensitive hexogen of the standard hexogen.
- DSC Differential Scanning Calorimetry
- IAD Detonation Ability Index
- the IAD test is performed according to standard NF T 70-502 (see also UN - Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria, Fourth revised edition, ST / SG / AC.10 / ll / Rev. 4, ISBN 92-1-239083-8ISSN 1014-7179 and STANAG 4488). It consists in determining the reactivity of an explosive substance subjected to detonation of a priming relay through a barrier consisting of cellulose acetate boards. The limit thickness of the barrier for which there is no initiation of the detonation of a second relay placed in contact with the other face of the test piece is determined. This method was early disclosed in 1958 in US Patent 2,832,213.
- Such a method is applicable to any type of explosive substance, solid, pasty or gelled. Its extension to liquid explosives is described in particular in US Pat. No. 2,832,213. US Pat. Nos. 5,472,531, 5,316,600 and 2 667 592 give examples of safety results obtained on different types of explosives by means of said method (IAD test).
- the IAD test applied directly to RDX crystals does not distinguish between the two product grades.
- the result of the IAD test on a reference composition PBXN-109 leads, in the case of the use of I-RDX ® to a number of cards between 120 and 150, whereas this number is significantly greater and can exceed 200. in the case of a PBXN-109 composition using RDX crystal.
- the IAD test can therefore be conclusive but it inherently has a certain number of drawbacks. He implies :
- MSIAC Munition Safety Information Analysis Center
- TAFM Anamic Force Microscopy
- the line widths are directly proportional to the number of defects (in the broad sense) in the crystal lattice.
- the NQR analyzes performed on seven hexogens show that the finer the peak, the more the hexogen is insensitive. This technique has the advantage of being achievable directly on the hexogen sample and requires only 5 to 10 grams of product. Its major disadvantage lies in the device itself (high cost and device not available on
- the inventors presently propose a new method, simple to implement, of differentiation of a crystallized hexogen of standard quality (sensitive) of a so-called insensitive crystallized hexogen.
- they propose an original process, simple to implement, of determining the sensitive or insensitive character of a crystallized hexogen.
- said method or method comprises:
- said matrix consisting essentially of at least one liquid polymer suitable for formulating binders for energetic materials charged with nitro organic explosives; and at least one adsorbent of volatile organic compounds, stable at the temperature of implementation of the analysis and having a low affinity for water.
- said method or method of the invention comprises an original formulation of the crystallized hexogen which makes it possible to discriminate both grades of hexogen by differential scanning calorimetry (DSC). It has been seen in the introduction to this text that said differential scanning calorimetry does not allow such discrimination when it is implemented directly on the hexogens in question ("pure hexogens").
- the method of the invention thus combines an original formulation of the crystallized hexogen (it has been incorporated, by mixing, in a specific matrix) with a particular analytical technique (differential scanning calorimetry).
- the originality of this invention lies in the nature of the matrix in which the hexogen is mixed for differential scanning calorimetry analysis.
- the analysis of a material by differential scanning calorimetry is a per se known analysis, familiar to those skilled in the art. It consists in determining the enthalpies of thermal phenomena (such as changes in physical state or thermal reactions), by measuring the differential heat flux necessary to maintain the sample of material, on the one hand and an inert reference, of on the other hand, at the same temperature.
- This type of analysis is for example used to compare the maximum temperatures of decomposition peaks of single substances and mixtures incorporating said substances.
- This type of analysis, known per se is therefore, according to the invention, implemented, typically, on a sample containing the crystallized hexogen (which one wishes to determine the sensitive or insensitive character) in an essentially constituted matrix :
- At least one liquid polymer suitable for the formulation of binders for energetic materials loaded with nitro organic explosives this type of material is obviously compatible with hexogen (nitrated organic explosive); it is conventionally used as a prepolymer in the formulation of binders for composite explosives ... and
- At least one adsorbent of volatile organic compounds stable at the temperature of implementation of the analysis (at least up to 230 ° C., or even well above 400 ° C. C and above) and having a low affinity for water.
- VOC adsorbents of the porous polymer type (having a large specific surface area), are especially commonly used as a stationary phase in gas chromatography columns.
- Said matrix is generally essentially composed of such a liquid polymer associated with such a volatile organic compound adsorbent. It is advantageously constituted at 100% r of such a binary association.
- said method is implemented on the hexogen itself (in a matrix but not within an explosive composition (see the IAD test));
- DSC analysis technique in question
- the crystallized hexogen is generally introduced into said matrix (by mixing) in such quantities that the charged matrix contains from 35 to 65% by weight of said hexogen.
- said loaded matrix (to be analyzed by DSC in the context of the process of the invention) contains: from 35 to 65% by weight of said crystallized hexogen, from 25 to 50% by weight of said at least one liquid polymer, and from 5 to 20% by weight of said at least one adsorbent.
- said charged matrix contains: from 46 to 59% by weight of said crystallized hexogen, from 31 to 43% by weight of said at least one liquid polymer, and from 8 to 14% by weight of said at least one adsorbent.
- Said at least one liquid polymer is advantageously chosen from polyethylene glycols, polyoxypropylene glycols, hydroxyl-terminated polyesters and polyethers. Those skilled in the art are aware of these inert, crosslinkable prepolymers, used in particular in the formulation of propellants (with nitro-organic explosives).
- Said polyethylene glycols, polyoxypropylene glycols, polyesters and hydroxyl-terminated polyethers advantageously have a molecular weight between 1500 and 5000 g / mol.
- Said at least one liquid polymer may also advantageously consist of a hydroxytelechéque polybutadiene (PBHT).
- PBHT hydroxytelechéque polybutadiene
- This type of compound is also widely used in the formulation of binders for energetic materials loaded with nitro organic explosives. For use for the purposes of the invention, it generally occurs with a molecular mass of between 500 and 10,000 g / mol, advantageously with a molecular mass of between 2,000 and 3,000 g / mol.
- Said at least one adsorbent of volatile organic compounds is advantageously a porous polymer based on a polyphenylene oxide with 2,6-diphenyl-p-phenylene oxide units.
- Said polyphenylene oxide (RN 24938-68-9) has the following formula:
- Tenax ® This type of adsorbent is notably commercially available under the name Tenax ®.
- Tenax ® There are actually different forms of Tenax ®: Tenax ® GC Tenax ® GR, Tenax ® TA ... commercialized by Aldrich companies, Supelco, Buchem BV Tenax ® -TA, since it has low affinity for water, is particularly effective in trapping volatile and semi-volatile organic compounds present in aqueous samples.
- Tenax®-TA is particularly recommended as an adsorbent of the hexogen formulation matrix, in the context of the implementation of the process of the invention.
- adsorbents of volatile organic compounds are likely to be suitable. They must of course meet the specifications set out above: - therefore be adsorbents of volatile compounds,
- the determination method of the invention involves the formulation of the hexogen (whose sensitivity or insensitivity is to be determined) in an essentially constituted matrix:
- porous polymer based on a polyphenylene oxide with 2,6-diphenyl-p-phenylene oxide units, whose molecular mass is between 0.5 and 1 x 10 6 g / mol.
- the DSC provides a fine exotherm, whose peak width is generally less than I 0 C, for the insensitive hexogen (I-RDX®) while it provides a wide exotherm, whose peak width is generally greater than 5 0 C, for sensitive or standard hexogen.
- the width of the peak means the width at half height;
- the analysis implemented as part of the method for determining the sensitive or insensitive nature of a crystallized hexogen, comprises obtaining and studying a thermogram, more particularly the study. of the shape of the peak of decomposition:
- thermogram of a reference sample This first variant is implemented in a context of blind work without reference. Obviously we do not know the exact nature of the hexogen that is submitted for analysis but we do not know either the thermogram of a reference sample ... We proceed to an "absolute" study of the thermogram of the sample obtained.
- the analysis implemented in the context of the method of the invention, comprises obtaining a thermogram and comparing it to at least one reference thermogram established for a given hexogen, whose sensitive character or insensitive is known.
- This second variant is not implemented in a context of blind work. It involves a preliminary analysis on a reference sample.
- said reference sample and said sample to be analyzed are formulated under similar or even identical conditions (nature of the matrix, concentration of hexogen in said matrix, conditions for carrying out the analysis, etc.).
- the exact nature of the hexogen that is submitted for analysis is not known, but at least one reference thermogram is available. A "relative" study of the thermogram of the sample obtained is carried out.
- the DSC analysis conducted on an original sample makes it possible to obtain the expected result: the determination of the sensitive or insensitive nature of the hexogen content in said sample.
- the present invention relates to formulated hexogen, for the implementation of the method described above; i.e. crystallized hexogen formulated in a matrix consisting essentially of at least one liquid polymer suitable for formulating binders for energetic materials loaded with nitro organic explosives; and at least one adsorbent of volatile organic compounds, stable at least up to 23O 0 C and having a low affinity for water.
- FIG. 1 shows the superimposition on the same temperature scale of the differential scanning calorimetry thermograms, implemented according to the invention, on a standard hexogen sample and on a hexogen type I-RDX® sample (hexogen insensitive). exampIe
- the described embodiment was applied to more than one hundred samples of crystallized hexogens (standard I-RDX® and RDX combined) and led to reproductive results within an acceptable standard deviation range. Correlations with the IAD characterizations have validated the results obtained by the method of the present invention.
- Hexogen is formulated by simply mixing the ingredients, used in the following proportions:
- Adsorbent 10 mg ⁇ 2 mg.
- the RDX intervenes in the state of powder. It could be formulated at particle sizes ranging from less than 3.5 ⁇ m to 800 ⁇ m.
- the liquid polymer is a hydroxytelechelic polybutadiene. Its viscosity is 500 poise at 30 ° C.
- the PBHT used is the PBHT R45HTLO sold by the company Sartomer.
- the adsorbent is Tenax ® -TA, sold by BV Buchem It comes in the form of a powder, the following characteristics: - size: 60/80 mesh
- the decomposition of RDX ® I-conditioning matrix according to the invention leads to an exothermic peak end width less than 1 ° C, of about 0.5 0 C under the conditions of the example.
- the decomposition is autocatalytic and leads under the conditions of the example to a temperature increase rate of the sample greater than that of the heating setpoint. The temperature of the sample is then higher than that of the set point of the analysis apparatus. After the decomposition reaction, the sample returns to the recorded temperature. It is customary to represent the decomposition mode thermogram by reducing the maximum of the measured temperature peak of the sample to the recorded temperature value. It is this representation which is given in FIG. 1 in comparison with the curve measured with standard matrix hexogen according to the invention.
- the width of the decomposition peak measured with standard hexogen is greater than 5 ° C. about 10 ° C. under the conditions of the example.
