Definitions
- the present invention relates to the preparation of noble metal oxalate complexes.
- noble metal oxalate complexes are also referred to below as noble metal oxalates. It relates in particular to the preparation of Edelmetalloxalat complexes of precious metal precursors and oxalic acid and / or oxalic acid salts.
- the preparation of noble metal oxalate complexes of noble metal precursors and oxalic acid and / or oxalic acid salts has long been known.
- the preparation of platinum oxalate complexes is usually carried out by reaction of platinum oxide hydrate (platinum (IV) hydroxo acid, dihydrogen hexahydroxoplatinate (IV), hydroxoplatinic acid) with oxalic acid at a temperature of 60 ° C. (K. Krogmann, P. Dodel , Chem. Ber. 1966, 99, 3408-3418).
- EP 0 254 935 A1 describes a process for the preparation of silver oxalate with a large particle diameter. According to this method, silver salt and oxalic acid or oxalic acid salts are reacted at a pH of not more than 5. The reaction is carried out at a temperature of 0 to 80 ° C, preferably at a temperature of 40 to 60 ° C.
- the preparation of precious metal oxalate complexes of noble metal precursors and oxalic acid and / or oxalic acid salts is an exothermic reaction in which heat and C0 2 are formed.
- the temperature may rise above the decomposition point of the Edelmetalloxalat complexes, which at the same time further C0 2 is released.
- a process for the preparation of noble metal oxalate complexes in which noble metal precursors are reacted with oxalic acid and / or oxalic acid salts and in which noble metal oxalate is introduced into the reaction mixture as an autocatalyst.
- Suitable starting materials according to the invention are precious metal precursors and oxalic acid and / or oxalic acid salts. Many starting materials are conceivable, with the educts of noble metal precursors and oxalic acid and / or oxalic acid salts, of course, differing from the end product noble metal oxalate.
- precious metal includes in particular the classical precious metals Pt, Pd, Ir, Rh, Os, Ru, Ag and Au, but also the semi-precious metal Re.
- Preferred noble metals are silver, palladium and platinum, platinum is particularly preferred.
- noble metal precursors are noble metal salts and noble metal oxide hydrate.
- noble metal salts are noble metal nitrate and noble metal lactate or mixtures thereof. It is also conceivable to use mixtures of noble metal oxide hydrate and noble metal salt or salts.
- preferred noble metal oxide hydrate, in particular platinum oxide hydrate has proven, which is also referred to as platinum (IV) hydroxoic acid (see Gmelin, Verlag Chemie GmbH, Berlin 1940, p 47-48). Which salt is used depends on the type of the precious metal. For example, silver oxalate can be prepared from silver nitrate.
- Platinum (IV) hydroxoacid or one of its salts such as, for example, K 2 Pt (OH) 6 , Na 2 Pt (OH) 6, etc., is preferably used as starting material for platinum oxalate. Basically, the free acid is preferred.
- Oxalic acid salts may be, for example, sodium oxalate, ammonium oxalate or potassium oxalate or mixtures thereof. However, it is also possible to use a mixture of oxalic acid and one or more oxalic acid salts. Again, the preferred starting materials depend on the type of precious metal. Thus, e.g. for the preparation of silver oxalate advantageous ammonium oxalate can be used. In principle, however, the use of free oxalic acid is particularly preferred. For example, particularly preferably oxalic acid is used for the preparation of platinum oxalate.
- a starting material combination of noble metal oxide hydrate and oxalic acid is particularly preferred since, in addition to noble metal oxalate complexes, only carbon dioxide and water are formed.
- Oxalic acid or oxalic acid salt is particularly preferably added in a suitable stoichiometric ratio.
- This reaction produces a mixture of different dioxalatoplatinic acids or platinum oxalate complexes. A detailed description of such mixtures can be found in K.Krogmann, P.Dodel, Chem. Ber. 1966, 99, 3402-3407 and 3408-3418.
- oxalic acid and / or oxalic acid salt is added depends on the precious metal oxalate complex to be prepared. It is preferably added in the form of an aqueous solution or in solid form. Oxalic acid is preferred and is preferably used in solid form as Oxalklaredihydrat.
- the reaction is carried out at a temperature which is below the decomposition temperature of the Edelmetalloxalat complexes.
- a risk assessment is to be used, the important procedural parameters, apparatus-technical parameters, safety considerations and safety-related data, such as the decomposition temperature and the Involving the decomposition of noble metal oxalate complexes.
- the reaction temperature can be approximated to the decomposition temperature.
- the reaction is thus preferably carried out at a temperature below the decomposition temperature of the Edelmetalloxalat complexes.
- the difference between the reaction temperature and decomposition temperature should be at least 1 ° C, preferably, the difference is at least 5 ° C.
- the decomposition temperature is defined as the incipient decomposition temperature, the incipient decomposition being determined by means of long-term differential thermal analysis in glass ampoules at a heating rate of 0.05 K / min according to temperature difference thermoanalysis according to DIN 51007.
- a temperature range between 0 ° C and 56 ° C has been found for the reaction between precious metal precursors and oxalic acid and / or oxalic acid salts, more preferably between 30 ° C and 52 ° C and most preferably between 35 ° C and 45 ° C.
- the reaction preferably at a temperature of up to 56 ° C, more preferably up to 52 ° C, and most preferably to 45 ° C is performed.
- the reaction is carried out above 0 ° C, preferably above 30 ° C and most preferably at a temperature of 35 ° C to 42 ° C.
- the decomposition temperature of the Edelmetalloxalat complexes is to be determined according to the invention by means of long-term differential thermal analysis (DTA) according to DIN51007 (Jun1994).
- the determination can be made of solutions of noble metal oxalate complexes corresponding to the product solution in a closed glass ampoule at a heating rate of 0.05 K / min between 0 ° C and a temperature above the measured peak minimum (see figure).
- the decomposition temperature according to the invention is understood to be the temperature of the first deviation (see FIG. 57 ° C.) of the measurement curve from the initial base curve (5.2 DIN 51007).
- an aqueous solution or suspension of noble metal oxide hydrate or noble metal salt is first prepared.
- an aqueous suspension of platinum oxide hydrate (H 2 [Pt (OH) 6 ] or platinum (IV) - hydroxoic acid) is preferably prepared first.
- the autocatalyst is added in an amount of 5x10 "4 to 1 x 10 " 2 molar equivalents of noble metal relative to the noble metal in the noble metal precursor and most preferably the autocatalyst is added in an amount of 5x10 "4 to 7x10 " 3 molar equivalents of noble metal relative to the noble metal in the noble metal precursor added.
- the autocatalyst is preferably added in aqueous solution. Typical concentrations are 5-20% by weight, for example 8-15% by weight.
- the noble metal oxalate complexes corresponding to the product to be produced are expediently used as the autocatalyst (corresponding to the meaning of the term "autocatalyst"), ie platinum oxalate is used as the autocatalyst for the preparation of platinum oxalate, silver oxalate is used as the autocatalyst for the preparation of silver oxalate.
- the order of delivery of noble metal precursor, autocatalyst and oxalic acid and / or oxalic acid salt is of minor importance.
- the autocatalyst may be added to the reaction solution or suspension simultaneously with the total amount of oxalic acid and / or oxalic acid salt, with a portion of oxalic acid and / or oxalic acid salt, or prior to the addition of oxalic acid and / or oxalic acid salt. In this case, either a solution or suspension of noble metal precursor be submitted or added later.
- the addition should take place at a temperature below the desired reaction temperature. Preferably, the addition takes place at a temperature of up to 37 ° C, more preferably up to 32 ° C.
- the forming reaction mixture is then heated to the desired reaction temperature. The rate of heating then depends on the onset of the reaction.
- the oxalic acid or the oxalic acid salt may be added in one or more portions.
- the portions can be the same size, but it can also be added several different sized portions. In the event that the portions are not the same size, advantageously a larger portion is added first and then one or more smaller or smaller and smaller.
- the solution or suspension is stirred during the reaction.
- the oxalic acid or oxalic acid salt is added depending on the stirring conditions, the concentration of the solution or suspension, and the reactor dimension. Basically, the rate at which oxalic acid or oxalic acid salt can be added is well adjusted by the evolution of C0 2 and the temperature evolution.
- the qualitative analyzes were carried out by NMR and UV spectroscopy.
- the UV spectrum was measured at room temperature using a Specord® 200 UV spectrometer from Analytic Jena AG in 1 cm cuvettes (quartz glass cuvettes QS Suprasil® from Heraeus Quarzglas GmbH) in a measuring range of 190 nm -1 100 nm with a resolution of .mu.m. 2 nm measured.
