Definitions
- the present invention relates to a process for packaging dianhydrohexitol in the form of an aqueous solution in a packaging material comprising at least one metal-based layer.
- the process according to the present invention is also inexpensive, which constitutes another advantage.
- the applicant company has demonstrated that only a dianhydrohexitol in the form of an aqueous solution - and not a solid product - was able to be stored in such a stable manner and this, in this type of packaging comprising at least one layer based on metal.
- the present invention also relates to the aqueous solution of dianhydrohexitol thus packaged, and all its uses including those in the food and pharmaceutical fields.
- Dianhydrohexitols also known as isohexides, are products of internal dehydration of hydrogenated C6 (hexitol) sugars such as sorbitol, mannitol and iditol.
- isosorbide is today the one for which the most industrial applications are envisaged, particularly in the plastics sector, as a chemical synthesis intermediate, but also in the food and pharmaceutical fields.
- it is generally necessary to have the purest compositions possible having in particular a content of dianhydrohexitols at least equal to 98.5% by weight, preferably at least 99.5% by weight by weight. compared to their total dry matter.
- dianhydrohexitols and in particular isosorbide are highly hygroscopic and chemically unstable products.
- the Applicant Company has in particular observed that the storage of isosorbide manufactured according to known methods, even in the absence of moisture from the atmosphere, could result in certain temperature conditions chemical degradation resulting, inter alia, in the formation of formic acid, which acid has a characteristic and unpleasant odor, particularly troublesome in pharmaceutical or other applications.
- the applicant company has thus been led to develop methods of purification and stabilization of dianhydrohexitols described in particular in patent applications EP 1 287 000 and WO 03/043959.
- the inventions relating to these applications concern both solid dianhydrohexitols and dianhydrohexitols in liquid form.
- a stable liquid isosorbide composition with a solids content of between 50% and 90% is disclosed in WO 03/043959. That being said, only the stability of the solid products was evaluated in these two applications, by storage of the samples to be tested in a plastic container respectively in polyethylene (EP 1287 000) and glass (WO 03/043959) bags, at a temperature of 60 ° C and 40 ° C, respectively.
- the applicant company found that the shelf life of solid dianhydrohexitols, determined under the conditions of the tests described in patent applications EP 1 287 000 and WO 03/043959, only imperfectly reflected the stability of these same products under real conditions of transport and storage.
- the Applicant Company has in particular noted relatively high concentrations of formic acid in the vicinity of the polyethylene film used conventionally to pack dianhydrohexitols in solid form, and in particular isosorbide in the form of powder.
- the Applicant Company found that by substantially increasing the concentration of antioxidants in the plastic layer in contact with dianhydrohexitol, the stability of this denier was substantially improved, especially when the dianhydrohexitol in question was isosorbide .
- the plastic packaging material being selected from polyethylene, polypropylene and copolymers of ethylene and propylene.
- antioxidant agent has the same meaning here as in the document WO 2009/019371, namely that it encompasses all the compounds capable of limiting or eliminating the thermo-oxidative degradation, also known by the term auto-oxidation of organic compounds, in particular organic polymers.
- the packaging process that is the subject of said application applies to liquid or solid dianhydrohexitols even if the solid form is preferred, and that a very preferred variant consists in packaging the dianhydrohexitol under an anhydrous and / or inert atmosphere. for example under a nitrogen atmosphere.
- This document states that to ensure optimal stability of dianhydrohexitol during transport and storage, it is necessary to provide an additional layer of protection against oxygen from the air, water vapor and / or light.
- the process that is the subject of said application therefore relates to a process for packaging a dianhydrohexitol, comprising:
- the surface of the container in contact with the aqueous solution of dianhydrohexitol consists of a metal-based layer optionally coated with a layer of lacquer based on polyester resin or epoxy resin.
- aqueous solution of dianhydrohexitol refers to a composition containing essentially water and at least one dianhydrohexitol. It is characterized in particular by its dry matter content, expressed in% by dry weight relative to its total weight. This is in particular between 40% and 95%, preferably between 50% and 90%, very preferably between 60% and 85%.
- the said aqueous solution of dianhydrohexitol should not be assimilated to another liquid form of dianhydrohexitol: namely a molten dianhydrohexitol, that is to say a dianhydrohexitol in a molten state at a temperature greater than or equal to 63%. - 2 ° (at atmospheric pressure).
- the dianhydrohexitols are synthesized in the presence of water (or water is generated during their synthesis): by recovering said dianhydrohexitol in this reaction medium, there is immediately available an aqueous solution of dianhydrohexitol used according to the invention .
- the solutions of dianhydrohexitols can in particular be obtained according to the processes described in the aforementioned patent applications EP 1 287 000 and WO 03/043959.
- aqueous solution in question may contain dianhydrohexitol alone, as it may contain several.
- dianhydrohexitols (1, 4 - 3, 6-dianhydrohexitols) include isosorbide (1,4 - 3,6-dianhydrosorbitol), isomannide (1,4 - 3,6 dianhydromannitol), isoidide (1,4 - 3,6-dianhydro- nititol) and mixtures of at least two of these products.
- the aqueous solution contains only one dianhydrohexitol which is isosorbide.
- packing process is meant an operation that involves placing a product in a container, with which it is in direct contact, to facilitate its protection and preservation.
- layer refers in this application to a uniform envelope; the term “metal-based layer” means that it consists mainly of said metal (said metal then representing at least 90% by weight, preferably 99%, very preferably 100% by weight of the total weight of said "layer”).
- metal refers to a material whose cohesion of atoms is ensured by the metallic bond: all the atoms of the object put one or more electrons in common. More precisely and referring to the periodic table of the elements, the diagonal starting from the Bore (B) and going up to the Polonium (Po) separates the metallic elements (lower left) from the non-metallic elements (at the top right) ).
- the metal-based layer can also be composed of an alloy that is to say a combination of a metal element with one or more other chemical elements to increase the mechanical or chemical resistance.
- a metal element mainly composed of iron and carbon
- stainless steel for which chromium and possibly other metals such as nickel, molybdenum, silicon, manganese or titanium are added. Vanadium or Tungsten.
- the surface of the container in contact with the aqueous solution of dianhydrohexitols consists of a layer based on metal.
- this layer is made of metal (made of 100% by said metal).
- the surface of the container in contact with the aqueous solution of dianhydrohexitols consists of a metal-based layer covered with a layer of varnish. According to this variant, it is the layer of varnish which is in contact with the aqueous solution of dianhydrohexitol.
- the varnish is based on polyester resin or epoxy resin, for example of the epoxy-phenolic type.
- the varnish is applied in liquid form and cured by heating on the metal layer of the container to form a dry film.
- the thickness of the layer of the container in contact with the aqueous solution of dianhydrohexitol does not play a determining role in the present invention. It may especially be between 50 ⁇ and 1 cm.
- the container is preferably a rigid material so as to be able to withstand the stresses associated with the packaging of a product in liquid form such as the aqueous solution according to the present invention. It may be a drum, a container, a tank, but more generally, it is therefore a rigid container, of any shape and any size whatsoever.
- the wall of the container may consist of one or more layers.
- the wall of the container may be a monolayer based on metal, in particular aluminum or stainless steel, or a multilayer comprising at least two layers, in particular a metal layer and a layer of varnish based on resin.
- the method according to the present invention therefore comprises the introduction into the previously described container of the aqueous solution of dianhydrohexitol previously described.
- This introduction is carried out by any means well known to those skilled in the art, including means suitable for handling and transferring products in liquid form, in particular dianhydrohexitol composition in liquid form. These means are, for example gravity filling from a storage tank located above the packaging material via a filling orifice, or with the aid of pumping equipment.
- a second subject of the present invention relates to an aqueous solution of dianhydrohexitol packaged in a container, the surface of the container in contact with the aqueous solution of dianhydrohexitols consisting of a metal-based layer optionally coated with a resin-based varnish polyester or epoxy resin.
- the invention relates to a container containing an aqueous solution of dianhydrohexitol, the surface of the container in contact with the aqueous solution of dianhydrohexitol consisting of a metal-based layer optionally coated with a varnish based on polyester resin or epoxy resin. More particularly, the surface of the container in contact with the aqueous solution of dianhydrohexitols consists of a metal-based layer covered with a layer of varnish based on polyester resin or epoxy resin, said epoxy varnish being preferably of type epoxy-phenolic.
- aqueous dianhydrohexitol solution on the one hand, and the metal-based layer, on the other hand, contain all the characteristics previously listed with respect to the process that constitutes the first subject of the present application.
- the present invention makes it possible to improve the storage stability of aqueous solutions of dianhydrohexitol, in particular a pH variation of less than 10% after two months, preferably after 3 months, at 50%. Therefore, the amount of antioxidants and stabilizers can be reduced.
- this second object according to the invention can also be characterized in that the dianhydrohexitol is chosen from isosorbide, isomannide, isoidide or mixtures of at least two of these products, is preferably isosorbide.
- the aqueous solution of dianhydrohexitol is also characterized in that it has a dry matter content of between 40% and 95%, preferably between 50% and 90%, very preferably between 60% and 85% relative to to its total weight.
- the container containing the aqueous solution of dianhydrohexitol can then be used in plastic applications, as a synthetic intermediate, or in the food and pharmaceutical sectors.
- said container containing said aqueous solution may be emptied completely or partially so as to recover all or part of the aqueous solution of dianhydrohexitol it contains.
- Said solution then used for the preparation of materials, in particular in the plastics sector, or for the manufacture of chemical synthesis intermediate, but also in the food and pharmaceutical fields.
- the invention can be better understood in the light of the examples which follow but which in no way be limiting.
- This example relates to the packing and storage of isosorbide, in solid or liquid form, said isosorbide having previously been stabilized with disodium phosphate.
- a solid isosorbide composition and a liquid isosorbide composition are manufactured as follows:
- reaction crude is then cooled to 100 ° C. and then neutralized with 11.4 g of a 50% (by weight) sodium hydroxide solution.
- the isosorbide composition thus neutralized is then distilled under vacuum (pressure less than 50 mbar).
- the isosorbide crude distillate, lightly colored (light yellow color), is then dissolved in 2-propanol at a temperature of 60 ° C., so as to obtain a 75% solution of MS. This solution is then cooled slowly over a period of 5 hours to a temperature of 10 ° C. A recrystallized isosorbide primer is added at 40 ° C.
- the crystals are then wrung out in a wringer and washed with 2-propanol. After drying under vacuum, the crystals are redissolved in water so as to obtain an MS of 40%.
- This solution is then percolated on a GPC 12-40 granular activated carbon column at a rate of 0.5 BV / h (Bed Volume or Bed Volume / hour).
- the decolorized isosorbide composition thus obtained is then passed, at a rate of 2 BV / h, successively on a PUROLITE C 150 S strong cationic resin column and then an AMBERLITE IRA 910 strong anionic resin column.
- NORIT SX + type activated carbon powder at 20 ° C for 1 hour. The activated carbon is used at a rate of 0.5% by dry weight / dry weight of solution.
- disodium phosphate stabilizing agent
- the isosorbide solution is concentrated in vacuo.
- the solution is concentrated until an 80% solids solution is obtained.
- Part of the solution is recovered for carrying out the tests 4, 5 and 6.
- the concentration of the remainder of the solution under vacuum is then continued for removal of the residual water.
- the melt obtained crystallizes on cooling in the form of a mass of large crystals which are then ground to obtain a white powder with a moisture content of 0.2%. This powder is recovered for tests 1, 2 and 3.
