Definitions
- the present invention relates to the field of preparation of substituted alkylcycloalkanones of the formula I.
- Substituted alkylcycloalkanones of the formula I are important intermediates, in particular for the synthesis of musk scents.
- Musk scents are an important component of perfumes.
- the preparation of selected compounds of the formula I is carried out according to DE19853862 A1 via the radical addition of hydroxy or acyloxyalkenes to cyclic ketones, using a suitable organic radical chain initiator.
- radical chain initiators used have disadvantages in use. For example, they must be continuously fed to the reactor, are irreversibly consumed in the reaction, and promote the formation of reaction by-products, particularly polymers.
- the formation of polymers is particularly disadvantageous in continuous processes since they are carried out over very long periods of time, so that even a low polymer formation rate has an adverse effect.
- the reaction must be interrupted from time to time due to increasing viscosity or increased deposits.
- radical chain initiators have disadvantageous properties, such as easy flammability, formation of explosive mixtures, irritating or toxic gases or intermediates. These properties mean that the safety-related effort in carrying out the reaction must be very high.
- the reaction also produces high levels of substituted di-, tri- and tetraalkylcycloalkanones, as a result of which the starting materials are increasingly consumed and can no longer be recovered.
- it is recommended to work under high pressure because of the high temperatures to be applied in order to reduce the loss of low-boiling substances. This requires a special flameproof equipment.
- the invention relates to a process for the preparation of a substituted alkylcycloalkanone of the formula I.
- R can be a hydroxy, carboxy, carbonyloxyalkyl, formyloxy, alkylcarbonyloxy, arylcarbonyloxy, benzylcarbonyloxyalkyl group or one of the following groups:
- R ' is an alkyl, aryl, heteroaryl, alkylaryl, cycloalkyl radical.
- polymers are understood as meaning macromolecules having a monomer number greater than or equal to 5.
- the proportion of the formed substituted di-, tri- and tetraalkylcycloalkanones is greatly reduced, whereby the consumption of the educts decreases, thus more starting materials can be recovered and reused.
- the metal oxides can be reoxidized and reused after the reduction.
- Compounds of the formula I are, for example, 2- (3-hydroxypropyl) -cyclododecanone and 2- (3-acetoxypropyl) -cyclododecanone.
- Compounds of the formula II are, for example, cyclohexanone, cyclooctanone, cyclododecanone and cyclohexadecanone.
- Compounds of the formula III are, for example, allyl alcohol, allyl acetate, allyl formate, allyl propionate, allyl benzoate and allyl phenylacetate.
- the process of the invention can be carried out very well with metal oxides selected from the group of copper oxides, iron oxides, manganese oxides, indium oxides, cobalt oxides, silver oxides and mixtures thereof. Particularly well may be selected from Ag 2 O, CuO, Fe 2 O 3, Fe3O 4, CuFe 2 O 4, Co3O 4, CoO, MnO 2, the method with metal oxides, ln 2 O 3 and their mixtures.
- Silver oxides such as Ag 2 O form under the reaction conditions silver level or very finely divided silver particles that erode heavily into the reaction medium, so that the cost of recovery, in particular the separation of the remaining constituents and the plant cleaning is increased.
- copper oxides, iron oxides, manganese oxides, indium oxides, cobalt oxides and mixtures thereof and / or CuO, Fe 2 O 3, Fe 3 O 4 , CuFe 2 O 4 , Co 3 O 4 , CoO, MnO 2, In 2 O 3 and mixtures thereof this disadvantage does not exist, they erode in the process not or only slightly and do not form metal mirror. The cost of recovery and cleaning the system is therefore lower.
- the metal oxides can preferably be used as powder or granules.
- the metal oxides may also be supported on a suitable inorganic support material, such as alumina.
- the process proceeds at temperatures in the range of 100 to 250 ° C, preferably in the range of 150 to 220 ° C and particularly preferably in the range of 160 to 190 ° C.
- the process can be carried out at atmospheric pressure or optionally under overpressure.
- the use concentration of the metal oxide 1 to 50 mol%, based on the molar amount of cycloalkanone of the formula II and preferably 5-25 mol%, based on the molar amount of cycloalkanone of the formula II.
- the space velocity (quotient from the continuously fed mass flow of compounds of the formulas II and III and the mass of the metal oxide). It is preferably 0.01 to 1 per hour and more preferably 0.02 to 0.5 per hour.
- the molar ratio of cycloalkanone of the formula II to the alkene derivative of the formula III can be between 1: 1 and 10: 1 and preferably between 2: 1 and 8: 1.
- the process can be carried out continuously or discontinuously.
- a discontinuous stirred tank reactor is suitable for carrying out the batchwise process.
- a continuous tubular reactor, stirred tank reactor, fixed bed reactor or trickle bed reactor is suitable for the continuous process.
- product mixture which, depending on the duration and the process parameters used, represents a mixture with a varying concentration of the educts and products.
- the product mixture can be separated by suitable separation processes, in particular by distillation, whereby the already high purity of the desired alpha-monoalkyl products can be further increased and optionally unreacted starting materials can be recovered and reused.
- the metal oxide used is reduced by the reaction.
- the reduced metal oxide is the metal formed from the metal oxide, metal oxide of a lower oxidation state or mixtures thereof. In the process, the reduced metal oxide forms on the surface of the solid metal oxide.
- a further advantage of the invention is that the metal oxide can be regenerated (reoxidized) after it has been reduced by the reaction according to the invention.
- the reoxidation can be carried out by the contact of the reduced metal oxide with an oxygen-containing gas.
- the reoxidation of the reduced metal oxide can be particularly effective with the aid of a heated oxygen-containing gas stream, wherein the gas stream has a temperature of 100 to 500 ° C.
- the oxygen content of the gas may contain at least 0.1% by volume of oxygen, based on the total amount of oxygen-containing gas, determined at 20 ° C. and 1013.25 hPa, in order to allow the reoxidation to proceed in a short time.
- the reduced metal oxide may be separated from the product mixture prior to contact with the oxygen-containing gas to reoxidize it.
- the preferred oxygen content of the oxygen-containing gas is at least 17 vol .-% and its temperature between 150 and 500 ° C, to allow a particularly rapid reoxidation.
- the metal oxide thus regenerated exhibits the same activity as the metal oxide originally used.
- This procedure can For example, be applied in a batch process. It is also suitable for a continuous process, wherein, for example, at the beginning of the process at least two separate subsets of metal oxide are present. First, one of the subsets of the metal oxide is charged with a reactant stream and a product stream is removed.
- the reactant stream is passed to another subset of the metal oxide and the reaction is operated over it. Meanwhile, the first subset, which is now reduced to some degree, is separated from the product mixture and reoxidized with the oxygen-containing gas stream. Subsequently, it is possible to switch over to the first or a further subset of metal oxide and the process can thus be operated continuously.
- the process can be operated particularly advantageously if an oxygen-containing gas stream is introduced into the reactor during the course of the alkylation reaction.
- the oxygen-containing gas stream should come into contact with the reduced metal oxide.
- the process can be operated continuously with little effort over a very long period of time, with appropriate continuous supply of starting materials and removal of the product mixture. Oxidative and reductive processes occur simultaneously.
- the preferred oxygen content of the oxygen-containing gas in this process is from 0.1 to 20% by volume and more preferably from 3 to 16% by volume so that particularly few by-products of radical side reactions are formed and rapid reoxidation of the reduced metal oxide is made possible.
- the temperature of the oxygen-containing gas stream should be identical to or close to the temperature in the reactor.
- the invention also encompasses a product prepared by the process of the invention.
- the product can be characterized as containing a very low concentration of substituted di-, tri- and tetraalkylcycloalkanones.
- Example 1 of DE 19853862 comparative example from the prior art
- the selectivity is only 12%.
- substantially more of the desired alpha-monoalkyl product is consequently formed based on the CDD used.
- a 1.9 cm diameter fixed bed glass reactor equipped with a liquid and gas metering device and a jacketed heater and a device for collecting the product mixture at the reactor outlet is charged with the intended amount of granulated CuO (50.7 g; 5 ml, particle diameter 0.71 -1, 25 mm).
- the granules are obtained from a powdery CuO by pressing, crushing the pellets and sieving the desired fraction.
- the free volume of the reactor interior is filled with inert corundum particles to minimize dead volume and fix the initiator.
- the mixture of cyclododecanone (CDD) and allyl acetate (AlAc) is allowed to flow in a ratio of 1: 7.5 at a flow rate of 2.9 g / h over the heated to 180 ° C initiator bed.
- air is passed through the reactor bed at a rate of 2 ml / min.
- the product mixture is collected and determined by gas chromatographic analysis of its composition.
- the selectivity to the monoalkylated product is 75.3%. Unreacted CDD is separated from the products by distillation and recycled.
