Definitions
- the present invention relates to a new process for the preparation of a bi-metallic ruthenium / tin catalyst.
- EP-A-0539274 describes a process for the preparation of aldehydes and their derivatives according to a process which consists in carrying out the reduction in the vapor phase in the presence of hydrogen, acids, esters or anhydrides carboxylic, in the presence of a bi-metallic ruthenium / tin catalyst.
- the catalysts which are particularly advantageous are the bi-metallic catalysts comprising tin and ruthenium, free of boron, which comprise ruthenium and tin used in amounts such that the tin / ruthenium molar ratio is at least 2, preferably between 2 and 10 inclusive and even more preferably between 2 and 6 inclusive.
- ruthenium represents between 0.1 and 50% of the weight of the catalyst.
- the ruthenium represents from 10% to 50% of the weight of the catalyst.
- a catalyst is used in supported form.
- the support can be chosen in particular from metal oxides, such as aluminum, silicon and / or zirconium oxides, or also from coals optionally activated by a well-known treatment with nitric acid, acetylene black, or resins.
- the ruthenium content of the catalyst is advantageously chosen between 0.1 and 20.0% by weight, and even more preferably, between 0.5 and 3.0% by weight.
- One mode of preparation of said catalysts described in EP-A-0 539 274 consists in mixing ruthenium chloride III and tin chloride II then adding the solid support.
- the disadvantage from which this process suffers is that it does not make it possible to obtain a perfectly homogeneous catalyst capable of being manufactured on an industrial scale. Indeed, tin chloride II partially hydrolyzes and precipitates at the surface of the support while the ruthenium III chloride penetrates into the pores of the support. It follows that the support is not uniformly impregnated with the precursors of the ruthenium and tin metals and that the catalyst obtained is not very homogeneous.
- the objective of the present invention is to provide a process for the preparation of said catalyst making it possible to overcome the aforementioned drawbacks.
- a ruthenium compound, a tin compound and an organic solvent are therefore involved in the process of the invention.
- the nature of the compounds providing the various ruthenium and tin elements used for the preparation of the catalysts of the invention is not critical.
- the metallic elements can be provided in the form of an inorganic derivative such as an oxide or a hydroxide. It is possible to use a mineral salt preferably, nitrate, sulfate, oxysurfate, halide, oxyhalide, silicate, carbonate or an organic derivative, preferably, cyanide, oxalate, acetylacetonate; alcoholate and even more preferably methylate or ethylate; carboxylate and even more preferably acetate. Can be used complexes, in particular chlorinated or cyanated complexes of said metals and / or alkali metals, preferably sodium, potassium or ammonium.
- a mineral salt preferably, nitrate, sulfate, oxysurfate, halide, oxyhalide, silicate, carbonate or an organic derivative, preferably, cyanide, oxalate, acetylacetonate; alcoholate and even more preferably methylate or ethylate; carboxy
- ruthenium halides for example ruthenium III or IV chloride, ruthenium V pentafluoride,
- tin halides and for example, fluoride, chloride or tin bromide II or IV,
- tin oxides II or IV in anhydrous or hydrated form,. tin nitrate II or IV or basic tin nitrate II, . tin orthophosphate II,
- organic salts of tin II such as acetate, tartrate, octoate, ethylhexanoate.
- a ruthenium compound is used in which the ruthenium has a higher degree of oxidation than that of the tin present in the tin compound.
- the ruthenium compound is preferably started from a ruthenium III halide, preferably a ruthenium III chloride. It is also possible to start with a ruthenium IV salt, but there is no additional advantage, all the more since it is more expensive. Preferably, therefore, a ruthenium III halide is used, which can be either anhydrous or hydrated.
- said compound does not contain too many impurities.
- ruthenium chloride RuC.3, x H2O comprising approximately 42 to 43% by weight of ruthenium can be used without disadvantage.
- tin compound use is preferably made of a tin II halide, preferably of tin chloride II.
- the salt can also be used in anhydrous or hydrated form.
- the commercial tin salt of formula SnCI 2 , 2 H 2 O is also used.
- the compounds of said metals are used in the form of an aqueous solution.
- concentration of these solutions is such that a homogeneous solution capable of being impregnated on a support is obtained.
- the ratio between the number of moles of ruthenium compound and the number of moles of tin compound varies between 0.10 and 0.5 , and preferably between 0.15 and 0.35. It should be noted that the lower limit is not critical since there is no disadvantage in using an excess of tin compound.
- the precursor is prepared in an organic solvent.
- a first characteristic of the organic solvent used in the process of the invention is to dissolve the compounds of the starting ruthenium and tin metals.
- a polar aprotic solvent having a boiling point above 50 ° C. and preferably between 50 ° C. and 120 ° C., and even more preferably between 80 ° C. and 100 ° C.
- ether-oxides and, more particularly, ie diethyl ether, dipropyl ether, diisopropyl ether, dibutyl ether, methyltertiobutyl ether, ditertiobutyl ether, ethylene glycol dimethyl ether, dimethyl ether; diphenyl ether, dibenzyl ether, anisole, phenetole, ie 1, 4-dimethoxybenzene, veratrole; 1,4-dioxane, tetrahydrofuran (THR,
- Aliphatic, cycloaliphatic or aromatic ketones preferably, acetone, methyl ethyl ketone, methylisobutyl ketone, diisobutyl ketone, methyl-n-amyl ketone, methyl isoamyl ketone, cyclohexanone, methylcyclohexoneone.
- ethylene glycol dimethyl ether, acetone and methyl isobutyl ketone are preferred.
- the amount of organic solvent involved can be very variable.
- the weight ratio between the precursor of the catalyst and the organic solvent can vary between 1 and 30%, preferably between 5 and 15%.
- the preparation of the catalyst precursor is carried out by mixing, in any order, the ruthenium compound (preferably ruthenium III chloride) with the tin compound (preferably chloride d 'tin II) and organic solvent.
- the ruthenium compound preferably ruthenium III chloride
- the tin compound preferably chloride d 'tin II
- the reaction mixture is brought to a temperature ranging from 20 ° C to 100 ° C, preferably between 70 ° C and 90 ° C.
- the duration of this operation can vary widely and it is specified by way of illustration, that a duration ranging from 1 to 3 hours is entirely suitable. Then, if necessary, the temperature is brought back to ambient temperature, that is to say a temperature most often between 15 ° C. and 25 ° C.
- a homogeneous organic solution of the catalyst precursor is thus obtained, which is then used to impregnate a support.
- the support can be in any form, for example, powder, beads, granules, extrusions, etc.
- support examples of support are given above such as metal oxides, such as aluminum, silicon and / or zirconium oxides, or even among activated carbon or resins .
- the ruthenium content is adapted by a person skilled in the art depending on the support (nature, specific surface).
- the ruthenium content of the catalyst is advantageously chosen between 0.1 and 20.0% by weight, and even more preferably, between 0.5 and 3.0% by weight.
- the metals are deposited on a support by impregnating said support with the organic solution obtained according to the method described above.
- the preferred organic impregnation solution comprises a ruthenium II compound and a tin halide IV in an amount of 1% to 20% by weight of ruthenium.
- the impregnation can be carried out by spraying the support set in motion, for example, by the rotation of a bezel, the organic solution comprising the precursor of the ruthenium and tin catalyst.
- the impregnation is carried out "dry", that is to say the total volume of the organic solution of the precursor used is approximately equal to the pore volume presented by the support.
- the pore volume it can be done according to any known technique, in particular according to the mercury porosimeter method (standard ASTM D 4284- 83) or else measure the quantity of water which it absorbs on a sample.
- the impregnated support is then subjected to a reduction operation.
- a preferred variant of the invention consists in carrying out a drying step beforehand.
- the drying is most often carried out in air at a temperature which can range from room temperature, for example 20 ° C. to 100 ° C.
- the drying time is continued until a constant weight is obtained.
- the reduction of said precursor is carried out by bringing it into contact with the reducing agent.
- the reduction is preferably carried out with hydrogen.
- the hydrogen can be injected at atmospheric pressure or under a slight pressure, for example from 0.5 to 10 bar, preferably between 1 and 2 bar.
- Hydrogen can also be diluted in an inert gas such as nitrogen or helium.
- the reduction reaction is carried out at a temperature of at least 350 ° C, preferably between 350 ° C and 6O0 ° C, and even more preferably between 400 ° C and 500 ° C.
- the reduction can also be carried out at the time of use in the event that the reduction reaction of a substrate is carried out in the presence of hydrogen.
- the ruthenium-tin supported catalyst thus obtained is particularly homogeneous and can be easily prepared on an industrial scale.
- It comprises a metallic phase covering at least in part said support comprising at least in part a ruthenium-tin intermetallic at least partially in the form of the defined compound of Ru3Srt7.
- the phase containing ruthenium and tin has an Sn / Ru atomic ratio at least equal to 2/3, advantageously 3/2, preferably 7/3. Furthermore, it is preferable that the Sn / Ru atomic ratio is at most equal to 3, advantageously 5/2.
- said phase covering at least partially said support contains at least 50%, advantageously 80%, preferably at least 90% of said intermetallic phase.
