Definitions
- the present invention relates to a process for the preparation of aldehydes by hydroformylation catalyzed by metals of the 8th to 10th group of the Periodic Table of the Elements in the presence of cyclic carbonic acid esters.
- hydroformylation The reactions between olefin compounds, carbon monoxide and hydrogen in the presence of a catalyst to form a carbon atom-rich aldehydes are known as hydroformylation (oxidation).
- hydroformylation with rhodium compounds generally offers the advantage of higher selectivity and is therefore usually more economical.
- complexes are mostly used which consist of rhodium and preferably trivalent phosphorus compounds as ligands.
- Hydroformylations are often carried out in the presence of solvents in order to be able to simply recycle the catalyst after the reaction product has been separated off.
- the high boiler mixtures which are formed as a by-product of the hydroformylation are used as solvents. Corresponding methods are described for example in DE 2062 703, DE 2 715 685, DE 2 802 922 or EP 017183.
- inert organic liquids DE 3 126 265
- reaction products aldehydes, alcohols, aliphatic and aromatic hydrocarbons
- Ester, ether and water can be used as solvents.
- GB 1 197 902 describes saturated hydrocarbons, aromatics, alcohols and n-paraffins used.
- Polar substances are understood to mean substances from the following classes of compounds: nitriles, cyclic acetals, alcohols, pyrrolidones, lactones, formamides, sulfoxides and water.
- carbonic acid esters as cobalt-catalyzed hydroformylation reactions as a polar additive
- the carbonic acid ester is used not as a solvent but as a promoter in the presence of organophosphine complexes.
- the carbonic acid esters are used in a molar ratio of 1: 2 to the cobalt compound.
- the olefin is used in a more than 100-fold excess over the catalyst metal and the carbonic acid ester.
- non-polar solvents aliphatic, alicyclic and aromatic hydrocarbons, ethers, amines, carboxylic acid esters, ketones, silanes, silicones and carbon dioxide.
- US 5 648 554 discloses selective extraction of high boilers and selective extraction the catalyst complex with polar solvents such as water, ketones, alcohols, nitriles, amides, diols and carboxylic acids.
- US 5 138 101 describes the extraction of the reaction product with alcohol-water mixtures.
- aldehydes can react with conventional phosphite ligands.
- the addition of water and / or carboxylic acid can lead to hydrolytic decomposition in the case of phosphite, phosphonite and phosphinite ligands.
- Amides can displace ligands from the metal center due to their complex formation properties.
- Alkadienes are known as catalyst poisons (P.W.N.M. van Leeuven in P.W.N.M. van Leeuven, C. Claver, "Rhodium Catalyzed Hydroformylation", Klüver Academic Publishers, Dordrecht, Boston, London, 2000).

- This process variant is suitable when using a polar catalyst and an optional further non-polar solvent.
- the non-polar solvent can also be identical to the starting olefin or the olefinically unsaturated compounds used, so that either the hydroformylation reaction is not carried out until conversion is complete (for example only up to 90%, preferably 80%) or by addition of the olefin or the olefinically unsaturated compound during or after the hydroformylation reaction.
- FIG. 1 Variant A of the process is explained in more detail by FIG. 1: synthesis gas (1), olefins or olefinically unsaturated compounds (2) and catalyst solution (3), which appropriately contains the cyclic carbonic acid esters, are reacted in the hydroformylation reactor (4).

- Variate B is preferably used when adding a non-polar solvent or solvent mixture that is not miscible with the cyclic carbonic acid ester. This variant is particularly useful when either no further feed olefin or no further olefinically unsaturated compound is to be added or when the hydroformylation reaction is carried out to a high or complete conversion.

- the fraction (10) is expediently returned to the hydroformylation reactor.
- Fraction (11) can optionally be freed of catalyst residues in a container (12) and is then fed to the distillation stage (14).
- the reaction products (15) are separated from the cyclic carbonic acid ester (16), which are returned to the hydroformylation reactor (4).
- the catalyst can also be separated off as an extraction by feeding at least part of the fraction (16) to the stream (8).
- the extraction can be single-stage or operated as a multi-stage process in countercurrent, countercurrent or crossflow.
- olefins or olefinically unsaturated compounds can be added before and after the hydroformylation reaction.
- the same olefins / olefin mixtures or olefinically unsaturated compounds are preferably used.
- process variant is particularly suitable when using a non-polar catalyst and when no additional non-polar solvent is to be used.
- Further variants are possible in process variant C: Either additional olefin or olefinically unsaturated compound can be fed in after the actual hydroformylation reaction, or the hydroformylation reaction can only be carried out up to a certain partial turnover (for example 50 to 70%).
- the phase separation gives a light phase (11) which contains the olefin or the olefinically unsaturated compound and the catalyst; this phase is returned to the hydroformylation reactor (4).
- the heavy phase (10) contains the reaction products and the cyclic carbonic acid ester and is subjected to a distillation (13) after an optional catalyst separation (12).

- Various procedures can be used for the technical implementation of the separation.
- Separation via falling film, short-range or thin-film evaporators or combinations of these apparatuses is preferred.
- the advantage of such a combination can, for example, be the separation of synthesis gas still dissolved in a first step as well as part of the products and the starting olefms still present (for example in a falling film evaporator) and then in a second step (for example in a thin film evaporator) to carry out the final separation of the catalyst.
- the extractive separation is advantageously carried out continuously. It can be carried out as a single-stage process or can be operated as a multi-stage process in counterflow or crossflow.
- reaction products freed from catalyst, excess synthesis gas and most of the solvent are further separated into aldehydes (alcohols), olefins or olefinically unsaturated compounds, solvents and by-products. This can be done, for example, by distillation. Olefin or olefinically unsaturated compound and / or solvent separated from the reaction discharge or the hydroformylation products can be recycled into the hydroformylation reaction.
- reaction gas which has been freed from synthesis gas and catalyst and, if appropriate, from solvent can be hydrogenated before or after olefin removal (removal of the olefinically unsaturated compound) and then worked up by distillation onto pure alcohol.
- the fraction containing the catalyst is expediently returned to the hydroformylation reaction. This is of course independent of the composition of the fractions in which the catalyst is dissolved.
- the method according to the invention can be carried out in one or more stages. After a first hydroformylation reaction, it is possible to go through a second hydroformylation step which, under “more severe” operating conditions, also converts the difficultly hydroformylatable, internal olefins to the desired aldehydes.
- a separation of unreacted olefins and products is preferably carried out first and not reacted products are fed to a further hydroformylation stage, which in turn differentiates between the different process variants, in those process variants in which unreacted olefins, If catalyst and optionally also free ligand are present in different fractions after the separation of the reactor discharge, it is possible to use a completely different catalyst system (different metal and / or different ligands) in the second hydroformylation stage. If unreacted olefins, catalyst and possibly free ligand are not present in different fractions, this is of course not possible.
- cyclic carbonic acid esters are also conceivable for other metal-catalyzed reactions.
- Areas of application are e.g. B. cyanation, hydrocyanation, isomerization of olefins, hydration, Heck reaction, condensation reactions such as aldol condensation or hydration or esterification reactions.
- a 31-stirring autoclave was charged under nitrogen with 1070 g propylene carbonate, 0.22 g rhodium nonanoate and 3.4 g tris (2,4-di-tert-butylphenyl) phosphite.
- the rhodium concentration in the reaction mixture was 40 ppm and the molar ratio of phosphorus to rhodium was 10.
- syngas molar ratio of hydrogen to carbon monoxide 1: 1
- 280 g of 1-octene were introduced. It was hydroformylated at a reaction pressure of 20 bar and a temperature of 100 ° C with stirring.
- the hydroformylation was carried out at a temperature of 100 ° C. and a synthesis gas pressure of 20 bar. After the reaction had ended, the mixture was cooled to ambient temperature and the phases were separated. The hydrocarbon phase containing the active catalyst complex remained in the reactor. The propylene carbonate phase predominantly containing the aldehyde was discharged from the reactor and worked up to the crude aldehyde at 125 ° C. and 25 hPa on a thin-film evaporator. The propylene carbonate obtained as bottom product was used together with 140 g of olefin mixture and the catalyst solution remaining in the reactor in an oxidation according to the procedure described above. (The return is carried out a total of eight times, see table 1 experiments 3.1 to 3.8.)
- Example 4 (Comparative Experiment to Example 3) Analogous to Example 3, a further series of experiments was carried out with the following differences: Instead of propylene carbonate and n-decane, tetrabutane was used as the solvent, a mixture of C 6 alkanes, which by oligomerization and subsequent hydrogenation of 1- Butene is created. After the reaction had taken place, the entire reaction mixture was distilled on a thin-film evaporator at 125 ° C. and 25 hPa. The crude aldehyde was obtained as the top product. The bottom product was a hydrocarbon mixture containing the catalyst and consisting predominantly of tetrabutane. This solution, together with 140 g of olefin mixture, was used again in an oxidation according to the procedure described above. (The return is carried out a total of eight times, see Table 1 experiments 4.1 to 4.8.)
- Table 1 summarizes the normalized gross rate constants for some feedback cycles from the example tests. The comparison shows that the catalyst activity remains practically constant in the example according to the invention, whereas a clear decrease in the catalyst activity can be observed in the conventional procedure practiced in the comparative example. The catalyst stability can thus be increased considerably by using the method according to the invention.
