Definitions
- adsorbents can also be obtained by polymerization of a monomer carrying a functional group, for example polymethacrylic acids, phosphonic acids, polyvinylpyridines, polyvinylpyrrolidones, polyvinyl alcohols, saponified polylactones or copolymers containing these units. The most adsorbents often described, are, polystyrenes gels or crosslinked having sulfonic functional groups -S0 3 H or trimethylammonium (CH 3 ) 3 N -.
- the subject of the present invention is a process for the preparation of an ultra-pure solution of hydrogen peroxide, characterized in that it comprises at least one sequence including the successive passage of the solution to be purified, over at least one bed of cation exchange adsorbents (AEC) and at least one bed of anion exchange adsorbents (AEA) and characterized in that the adsorbent beds each have a height to diameter ratio greater than 3.
- AEC cation exchange adsorbents
- AEA anion exchange adsorbents
- the subject of the present invention is in particular a method as defined above, for which said ratio is in particular between 5 and 10 and, more particularly approximately equal to 6.
- the flow rates of hydrogen peroxide solution can vary between 0.5 and 100, preferably from 1 to 50 and more particularly from 10 to 30.
- the hydrogen peroxide solution to be purified according to the present invention is an industrial aqueous solution having a concentration of 1 to 70% by weight and preferably from 5 to 50% by weight.
- the adsorbents are chosen from those described above.
- the anion exchange adsorbents will be fed in ascending mode, while the cation exchange adsorbents will be fed in descending mode. It is possible to define the geometries of the beds so that the true flow rates and / or space velocities in each adsorbent are optimized. It is also possible to work under pressure, preferably, a working pressure of less than 5 atm relative will be chosen.
- the temperature of the solution to be purified according to the process as described above is less than or equal to 30 ° C and, preferably, between -10 ° C and + 10 ° C.
- At least one bed of anion exchange adsorbents contains carboxylate ions of formula R-COO- in which R represents a hydrogen atom, an aryl radical containing from 6 to 10 carbon atoms, or an alkyl radical containing from 1 to 4 carbon atoms, said aryl and alkyl radicals being either unsubstituted or substituted by one or more fluorine atoms.
- carboxylate ion of formula R-COO- is meant in particular the trifluoroacetate ion or the benzoate ion, the formate ion, the acetate ion, the fluoroacetate ion and, preferably, the acetate ion.
- the process comprises, upstream or downstream, sequences of passage over the beds of adsorbent ion exchangers of the solution to be purified, one or more purification steps such as, for example, distillation. liquid extraction, crystallization, absorption, filtration, ultrafiltration, nanofiltration, or reverse osmosis. If necessary, the initial solution is previously put under the desired title and then purified. Depending on the degree of purity and dilution of the hydrogen peroxide solution to be purified, one or more of these additional steps are carried out.
- the industrial hydrogen peroxide solution to be purified which is at a concentration of 30% to 70%, by weight, is previously distilled and put to the desired title, then purified on at least two ion exchange adsorbent beds, according to the sequence which is the subject of the present invention.
- a hydrogen peroxide solution of industrial quality or of so-called "food" quality having a concentration of approximately 50 to 70% by weight is subjected to the following preliminary treatment: a first distillation / concentration step to obtain a condensate having a concentration greater than 80%, plus a first purification by crystallization at low temperature and the removal of the supernatant.
- the crystals collected are washed, drained, then melted and the solution obtained is diluted to 30 or 35% with deionized water of ultra-pure electronic quality.
- a second bed of anion exchanger adsorbent may be added to the purification chain to retain the carboxylate ions released by the co plexation of metallic impurities in the first bed of anion exchanger adsorbent. It is thus very easy to obtain, from an ordinary industrial grade, a solution of hydrogen peroxide of "electronic" grade containing less than 200 ppt of each of the metal cations of columns IA to VIIA (excluding l 'oxygen) and columns IB to VIII of the table of the periodic table of the elements.
- the invention also relates to an installation for implementing the method as defined above.
- the anion exchange adsorbent beds are supplied in ascending mode and the cation exchange adsorbent beds are supplied in descending mode.
- the installation it is located on the customer's site such as, for example, a site for manufacturing electronic components, and connected directly to the point of use of the hydrogen peroxide by the latter. this.
- the ppt concentrations in the main critical elements are as follows: b) Example according to the invention Using the same material, but working with 7.6 liters in each of the beds, which corresponds to a height of approximately 71 centimeters and a ratio of bed height / diameter equal to approximately 6 960 liters of a new batch of solution A are purified at the rate of 140 liters per hour, which corresponds to a residence time of 1.3 minutes equivalent to that of the comparative example. Analysis of the critical elements gives the following results:
