Definitions
- the invention relates to a new process for the purification of hydrogen peroxide solutions, as a result of which highly pure solutions are obtained which can be used in semiconductor technology under the currently high purity requirements.
- the chemicals used are subject to the highest purity requirements. If the production of 1 megabit chips tolerated a chemical quality with impurities in the low ppm range, the production of 4 to 16 megabit chips requires chemical qualities with maximum impurities in the range of less than 10 ppb.
- the solutions contain volatile or steam-volatile organic carbon compounds from the anthraquinone process which cannot be easily removed by distillation.
- the content of dissolved organic carbon in the hydrogen peroxide can be up to 150 mg / l.
- metal ions and carbon impurities in hydrogen peroxide have a particularly disruptive effect in the production of microchips, these impurities having a more critical effect the more integrated the chips to be produced are to be. There has therefore been no lack of attempts in the prior art to remove the impurities from the hydrogen peroxide by aftertreatment with cation and / or anion exchangers.
- ion-exchanging materials for the removal of cations are substituted aromatic hydrocarbon-cation exchange resins and for removal of anions aromatic hydrocarbon-anion exchange resins containing tertiary amino or ammonium groups or pyridine rings. Due to the functional groups contained in these ion exchange resins, the ion exchange resins are often so sensitive to oxidation that when cleaning hydrogen peroxide these ion exchange resins have to be worked at relatively low temperatures of about 0 ° C. and with special precautionary measures.
- the epoxides or hydroperoxides formed can not only decompose explosively, but under certain circumstances even detonate.
- the use of cation exchangers or anion exchangers for cleaning hydrogen peroxide solutions is therefore problematic and requires special care.
- EP-A1-0 502 466 and DE-A1-38 22 348 A1 have described processes for purifying hydrogen peroxide solutions, according to which metal ions contained in corresponding solutions after purification by distillation are used by chelating agents and not by ion-exchanging polymeric adsorbents based on styrene-divinylbenzene copolymers are separated off.
- this method has the disadvantage that undesired chemicals have to be added to a pre-cleaned solution, which then have to be separated off again.
- the object was therefore to provide a process for the purification of hydrogen peroxide solutions which is simple to carry out, as a result of which the concentration of organic impurities (TOC) can be reduced to less than 5 ppm and at the same time interfering metal ions can be separated off.
- TOC organic impurities
- the object according to the invention is achieved by a process for purifying hydrogen peroxide solutions by crosslinking the hydrogen peroxide solutions to be purified, which have concentrations in the range from 5 to 59%, a) with an anion exchange resin, b) with a nonionic adsorber resin in the form of a hydrophobic aromatic Polymers with a macroporous structure, and c) are treated with a neutral adsorber resin from the group of styrene-divinylbenzene resins with a highly macroporous structure, the latter being formed by a pyrolysis treatment of the resin, with the proviso that the treatment with the adsorber or exchange resins can be carried out in any order, but on the condition that the treatment with the neutral adsorber resin takes place in the last stage.
- a resin selected from the group of strongly or weakly basic styrene-divinylbenzene resins can be used as the anion exchange resin with quaternary ammonium groups as functional groups and strong or weakly basic styrene-divinylbenzene resins with tertiary amino groups as functional groups.
- aromatic crosslinked polymers with a macroporous structure in particular selected from the group of styrene-divinylbenzene resins with a macroporous structure and a large surface area, are used as the nonionic adsorber resin.
- a resin selected from the group of styrene-divinylbenzene resins with a highly macroporous structure and a moderate surface is used as the neutral adsorber resin.
- the hydrogen peroxide solution to be treated is treated according to the invention with a flux density of 0.2 l / h cm 2 to
- the purification of these hydrogen peroxide solutions is carried out at temperatures from 15 to 25 ° C., preferably at 20 ° C.
- the process is particularly advantageous and economical under continuous conditions. However, it can also be carried out in batch mode
- the object can also be achieved by a corresponding method, in that the hydrogen peroxide solution to be cleaned is placed in fluid beds connected in series, which are separated from one another a) an anion exchange resin, b) a nonionic adsorber resin and c) a neutral adsorber resin containing with a residence time of 0.0008 to 20.0 min, wherein the hydrogen peroxide solution to be purified is separated from the exchanger or adsorber resins by filtration.
- the purification can be carried out in series-connected fluidized beds at temperatures from 0 to 20 ° C., in particular at 0 to 10 ° C., and can take place both in batch mode and continuously.
- 5 to 59% strength hydrogen peroxide solutions can be used in the process according to the invention.
- the hydrogen peroxide solutions used in the process according to the invention are pre-purified solutions by distillation which, as impurities, contain only very small amounts of ionic inorganic impurities, such as, for example, metal cations Al, Fe, Zn etc. or anions such as NO 3 "" , P0 4 2_ etc., and contain manufacturing-related organic contaminants.
- ionic inorganic impurities such as, for example, metal cations Al, Fe, Zn etc. or anions such as NO 3 "" , P0 4 2_ etc.
- the TOC content of a 50% hydrogen peroxide solution can be reduced from 40 ppm to less than 5 ppm by the process according to the invention, so that the solution obtained has a purity which is imperative for use in the semiconductor industry under the current requirements. It has been shown that the reduction in the TOC content only takes place in the desired manner by treatment with the three different resins mentioned above.
- Hydrogen peroxide solutions which may have been pre-purified by distillation can be purified by successive contact with the exchange resin and the various adsorber resins by mixing in separate fluidized beds, but preferably by contact with the corresponding resins in filled columns.
- the flow rate of the hydrogen peroxide solutions is to be set so that the content of carbon and of the ionic impurities in the eluate does not exceed the maximum tolerable amount.
- Flow densities of 0.2 to 1.0 l / h cm 2 in particular 0.5 to 0.7 l / h cm 2 , are expediently set.
- the purified hydrogen peroxide flowing out of the adsorption column is collected in a suitable container. If the purification is carried out in suitable fluid beds, the hydrogen peroxide solution is separated off by filtration and collected in a suitable container. Here, however, the dwell time must be set so that undesired impurities are adsorbed, but reactions with the resins do not occur. It has been found that under suitable conditions gene, ie at a temperature of 0 to 20 ° C, preferably between 0 and 5 ° C, at normal pressure and a residence time of the hydrogen peroxide solutions between 0.008 and 20.0 min good purification results are obtained, but at the same time no reaction with the exchange resins due to changes in the oxygen content of the hydrogen peroxide solutions or by means of heating.
- the sequence of the treatment in series with different resins is in itself arbitrary. Particularly good results are achieved due to the absorption capacity if the neutral adsorber resin is used in the last purification stage. However, particularly good results are achieved if the sequence of anion exchange resin, non-ionic adsorber resin and then neutral adsorber resin is followed. This sequence is particularly important because the adsorbing capacity of the neutral adsorbent would be the limiting factor of the process and a complex optimization of the volume flows in the different purification stages and the ratio of the column volumes to each other would be necessary. However, if the columns are connected in series in the preferred manner, this effort is unnecessary. This process parameter is unproblematic in particular if the treatment with neutral adsorber resin is carried out last.
- Strongly basic anion exchange resins which can be used are those based on styrene / divinylbenzene.
- a corresponding resin is commercially available, for example, under the trademark Amberlyst A-26 ® (manufacturer Rohm & Haas). Active groups of this resin are -N (CH 3 ) 2 CI.
- Other resins with the same active groups are Amberlyst A-15 ® , Amberlyst A-21 ® , and Amberlyst A-27 ® .
- Suitable resins are also Amberjet ® 4200 Cl, Amberjet ® 4400 Cl, Amberlite ® IRA 402 Cl, Amberlite ® IRA 404 Cl, Amberlite ® IRA 900 Cl, Amberlite ® IRA 904 Cl, Amberlite ® IRA 400 Cl, Amberlite ® IRA 410 Cl, Amberlite ® IRA 420 Cl, Amberlite ® IRA 440 Cl, Amberlite ® IRA 458, and Amberlite ® I6766.
- the weakly basic anion exchange resins IRA-35, IRA-93, IRA-94 and IRA-68 sold under the trademark name Amberlite ® are also suitable. They can also be used under the names Dowex, Diaion Type I and
- the functional groups of the named anion exchangers are oxidatively attacked by hydrogen peroxide solutions, it has been found through experiments that this can be completely or almost completely prevented by setting suitable operating parameters. Depending on the solution to be treated, this can be done by setting a high volume flow and / or -1 by appropriate cooling. If necessary, the process is carried out with cooling down to 0 ° C. However, it has been shown that this is usually only necessary if higher percent solutions have to be purified. This is not necessary when purifying solutions in the lower concentration range, since on the one hand, by setting a suitable volume flow, reactions can be kept very low or avoided, and on the other hand local temperature changes can be prevented.
- Nonionic adsorber resins which can be used in the process according to the invention are those based on styrene / divinylbenzene with a macroporous structure and
- adsorbents are free of washable components, such as. B. monomers or polymerization aids. These adsorbents have no ionic functional groups and are therefore completely nonionic hydrophobic polymers whose adsorptive properties are based exclusively on the macroporous structure, the white
- Non-ionic adsorber resins adsorb and release ionic species through hydrophobic and polar
- these resins are stable in pH ranges from 0 - 14, as well as against temperatures of up to 250 ° C. Under process conditions, these resins are active both at ambient temperatures, ie at temperatures from 20 to 30 ° C. But they are also at lower temperatures, such as. B. 0 ° C and lower, can be used.
- Suitable neutral adsorber resins are e.g. B. those based on carbonized styrene / divinylbenzene resins with a highly macroporous structure and a moderate surface. Such resins are commercially available, for example, under the trademark Ambersorb ® . In the invention Processes are Ambersorb ® 563, Ambersorb ® 564 ,. Ambersorb ® 572, Ambersorb ® 575, Ambersorb ® 600, Ambersorb ® 1500. These different specifications are carbonized adsorbents, made from highly sulfonated, macroporous styrene / divinylbenzene ion exchange resin, which has been pyrolyzed in a special process. Corresponding adsorbers have a uniform porosity, constant hydrophobic properties and excellent mechanical stability due to their manufacturing process.
- the adsorber resin is more accessible (more effective) for higher molecular organic components
- the process according to the invention can be carried out in batch mode, with the exchanger and adsorber resins used being regenerated each time after purification of a certain amount of hydrogen peroxide solution.
- each column can be regenerated individually, the volume flow does not have to be interrupted, and there are no idle times.
- the limiting factor is no longer the adsorption capacity of the resins used.
- the process according to the invention is carried out under and under conditions and methods known to the person skilled in the art.
- Good purification results are achieved with columns which have a ratio of column height to column diameter of between 7.5: 1 to 2.5: 1, preferably between 6: 1 to 4: 1, particularly preferably of 5: 1, which varies from hour to hour 3 to 5 times the volume of the bed volume of hydrogen peroxide solution.
- the method can also be carried out in columns which have heights of 10 to 200 cm and diameters of 1 to 2 cm.
- columns with heights of 2.5 to 4 m are particularly suitable, the diameters of which are between 0.50 and 0.8 m.
- the present invention provides a particularly simple and advantageous method for purifying hydrogen peroxide for applications in microelectronics.
- the process according to the invention is characterized in particular by the fact that very low levels of organic impurities in hydrogen peroxide solutions to reduce the effects very effectively and, moreover, to almost completely remove particularly troublesome cations such as Na, K, Mg, Al, Ca, Fe, Zn, Cu.
- the hydrogen peroxide solutions purified by the process according to the invention have increased stabilities and correspond to today's purity requirements for the production of highly integrated chips.
- Anion exchange resin Amberlys it.® A 26
- Non-ionic adsorbent resin Amberlite ® XAD-4 Neutral adsorbent resin: Ambersorb ® 563
- TOC determination with Shimadzu TOC 5000 (measurement method is based on the complete decomposition of the sample on a platinum catalyst at elevated temperature.
- the carbon dioxide formed from it is summarized using an infrared spectrometer. Cations and anions have not been determined specifically.
- the test demonstrates the excellent mechanical stability and chemical resistance of the 3rd stage also against more concentrated hydrogen peroxide solutions and shows that the 3rd stage again has a significant purification effect in the range TOC ⁇ 5 ppm.
