Definitions
- the present invention relates to catalyst systems for the oxidative carbonylation of dienes, in particular of butadiene to pentadienecarboxylic acid esters (PCSE) and methoxypentenoic acid esters (MPSE) and dehydroadipoic acid esters.
- PCSE butadiene to pentadienecarboxylic acid esters
- MPSE methoxypentenoic acid esters
- dehydroadipoic acid esters in particular of butadiene to pentadienecarboxylic acid esters (PCSE) and methoxypentenoic acid esters (MPSE) and dehydroadipoic acid esters.
- cocatalytic ligand or coordination complex compounds of the metal salt compounds and stoichiometric or catalytic amounts of a primary, secondary or tertiary alcohol can optionally also be used.
- No. 4,236,023 describes the oxidative carbonylation of butadiene to 1,3-pentadienecarboxylic acid ester.
- the catalysts described above are also used here. It works with catalytic amounts of alcohol and stoichiometric amounts of water scavenger (enol ether), based on butadiene, so that only simple carbonylation on butadiene is possible.
- the catalyst systems described have the disadvantage that they contain copper and halogen and therefore very corrosive mixtures are formed under the reaction conditions, which require the use of high-quality metal alloys.
- water scavengers are required in the copper-containing systems, since the oxidative carbonylation always forms oxalic acid esters (reaction of carbon monoxide with alcohol) as a by-product, which is saponified to oxalic acid by the water liberated in the reaction. Copper forms insoluble oxalates with oxalic acid, the copper oxalates precipitate out and the copper is thereby removed from the catalyst system.
- No. 4,575,562 and 4,868,328 describe further catalyst systems for oxidative carbonylation.
- Quinones e.g. 1,4-benzoquinone, tetrachloro-l, 4-benzoquinone
- Quinones are used to reoxidize e.g. Ruthenium, rhodium, palladium, osmium, iridium, platinum, especially palladium use.
- the autoclave experiments described are carried out with the exclusion of oxygen, so that the catalysis is stoichiometric, based on the quinone, and the corresponding reduced reaction product of the quinone has to be reoxidized in a second separate step.
- the quinones must therefore be used in large excess.
- the object of the present invention was to develop a new catalyst system to develop for the oxidative carbonylation of dienes, which avoids the disadvantages of the known systems such as corrosion, required water scavenger, multi-stage process. It has now been found that with a catalyst system composed of at least one metal or a compound of a metal from subgroup 8 of the Periodic Table of the Elements, preferably palladium on a support or a palladium (II) compound and a heteropolyacid, as described below, with high palladium activities under non-corrosive conditions in the absence of a water scavenger, the oxidative carbonylation of, for example, butadiene is successful.
- PCSE and MPSE are obtained as products.
- DMB 1,4-dimethoxy-2-butene
- the invention also relates to a process for the oxidative carbonylation of dienes, in which one or more diolefins, a primary, secondary or tertiary alcohol, carbon monoxide and oxygen are reacted at a temperature of more than 40 ° C. on a catalyst system, the catalyst system being at least one Metal or a compound of a metal of subgroup 8 of the Periodic Table of the Elements and a heteropolyacid of the general formula I
- additives in the reaction solution such as dehydrating agents, other oxidizing agents and inorganic solvents, generally does not require the reaction, but does not interfere with the course of the reaction.
- the invention includes carrying out the reaction under discontinuous (batch mode of operation), continuous or semi-continuous conditions.
- the reaction can be carried out in one or more stages.
- the heteropolyacid component of the catalyst systems corresponds to the composition with the formula:
- X P because it is difficult to produce heteropolyacids in which a is greater than three, especially when 12-a-b is greater than zero.
- the oxidation potential of heteropolyacid should be greater than that of palladium (II).
- the heteropolyacid can also consist of a mixture of compounds, so that the number of peripheral atoms can vary slightly and this can result in odd numbers in the formula.
- the heteropolyacid is normally isolated as a hydrate, which can contain up to 40 molecules of water per molecule of heteropolyacid.
- each conjugated diolefin can be used in the process described in the sense of the invention.
- the possible conjugated diolefins can be described by the following general formula ⁇ :
- R 1 , R 2 , R 3 and R 4 which can be the same and different from one another, can be hydrogen, halogen, an alkyl group consisting of 1 to 4 carbon atoms or an aryl group consisting of 6 ring carbons.
- 1,3-butadiene Isoprene; 1,3-pentadiene; 1,3-hexadiene; 2,4-hexadiene; 2,3-dimethylbutadiene; 2,3-diethylbutadiene; 1,4-diphenylbutadiene; Chloroprene; 1,3-heptadiene; 2-ethyl-1,3-butadiene; 1- phenylbutadiene; 2-chloro-3-methylbutadiene etc.
- the conjugated dienes can contain alkanes and alkenes which do not inhibit the reaction. 1,3-Butadiene and isoprene are preferred, 1,3-butadiene is particularly preferred.
- Primary, secondary or tertiary alcohols with up to six carbon atoms are preferred due to their availability and reactivity.
- Primary alcohols and in particular methanol and ethanol are preferred.
- the compounds of a metal of the platinum group (8th subgroup of the periodic table) used as catalysts according to the invention are palladium, platinum,
- Palladium (II) compounds or supported palladium (0) are particularly preferred.
- the choice of the palladium (II) compound is not critical.
- the palladium compound can consist of a simple salt such as palladium bromide, palladium acetate, palladium nitrate or palladium sulfate.
- the palladium compound should preferably be at least slightly soluble in the reaction medium.
- the following palladium compounds are also possible catalyst components:
- Palladium can also be used as a supported catalyst component.
- Possible carriers are: aluminum oxide, silicon dioxide, silica gel, kaolin, kieselguhr, zirconium oxide, titanium oxide, barium carbonate, zeolitic silicon and aluminum oxides, polyethyleneimine / silicon dioxide and activated carbon.
- the palladium concentration on the supports varies from 0.1 to 20% by weight. 0.5 to 5% by weight are preferred.
- the heteropolyacid used in the process is used in a two-fold to 10-fold molar excess, based on palladium. A four-fold to 100-fold molar excess, based on palladium, is preferred.
- Palladium can be used in very low concentrations.
- the proportions of the platinum group metal compounds used are about 0.001 to 5% by weight of the diolefin used, preferably between about 0.01 and 2% by weight, based on the diolefin used. Larger and smaller amounts can be used at different pressures and temperatures.
- the amount of alcohol is not critical as long as there is enough alcohol to form the ester.
- the alcohol can also serve as a solvent.
- the alcohols can be used in concentrations of 200 to 1000% by weight, based on the diolefin. However, larger or smaller amounts of alcohol can also be used.
- Benzonitrile, acetonitrile, isocyanates, isothiocyanates, pyridine, pyrimidine, quinoline and isoquinoline can also be used as solvents, which then serve as ligands to modify the activity or solubility of the platinum group metal catalyst.
- the CO / O 2 partial pressure ratio which describes the molar ratio, is generally 1/1 to 20/1. However, other ratios can also be used. Ratios of 2/1 to 10/1 are preferred.
- the total pressure under reaction conditions is usually 10 to 200 bar, 60 to 120 bar are preferred.
- an organic dehydrating agent can also serve as a solvent together with the alcohol.
- Typical dehydrating agents are acetals, ketones and orthoesters. A large number of such dehydrating agents are described in DE-A-30 43 816.
- the process can be carried out over a wide temperature range, from 40 ° C. to 200 ° C., preferably at 75 ° C. to 125 ° C.
- the reaction time is also not critical and can be varied widely (1 to 24 hours) depending on the reactant and reaction conditions.
- PCSE pentadienecarboxylic acid ester
