Definitions
- the present invention relates to a process for the oxidation of tertiary amines and nitrogen-containing aromatic heterocycles to amine oxides.
- the object of the present invention is therefore to provide a process for the oxidation of tertiary amines and nitrogen-containing aromatic heterocycles to amine oxides, which avoids the disadvantages mentioned above.
- This process should in particular be able to be carried out in a simple, reproducible manner with increased safety for humans and the environment and with good yields, and the reaction conditions should be very easy to control.
- This object is surprisingly achieved by the process according to the invention for the oxidation of tertiary amines and / or nitrogen-containing aromatic heterocycles in which at least one tertiary amine and / or at least one nitrogen-containing aromatic heterocycle in liquid or dissolved form with at least one oxidizing agent in liquid or dissolved form is mixed in at least one microreactor, reacted during a residence time and the amine oxide (s) formed is, if appropriate, isolated from the reaction mixture.
- individual tertiary amines or nitrogen-containing aromatic heterocycles or mixtures of at least two of these compounds can be reacted by the process claimed.
- a microreactor in the sense of the invention is a reactor with a volume ⁇ 1000 ⁇ l in which the liquids and / or solutions are intimately mixed at least once.

- the microreactor is preferably connected via an outlet to at least one retention zone, preferably a capillary, particularly preferably a temperature-controlled capillary.
- the liquids and / or solutions are passed into this residence zone or capillary after they have been mixed in the microreactor in order to extend their residence time.
- the residence time in the sense of the invention is the time between the mixing of the starting materials and the working up of the resulting reaction solution for the analysis or isolation of the desired product (s).
- the required residence time in the process according to the invention depends on various parameters, such as, for example, the temperature or the reactivity of the starting materials. It is possible for the person skilled in the art to adapt the residence time to these parameters and thus to achieve an optimal course of the reaction.
- the residence time of the reaction solution in the system used, comprising at least one microreactor and optionally a residence section, can be set by selecting the flow rate of the liquids and / or solutions used.
- the reaction mixture is likewise preferably passed through two or more microreactors connected in series. This ensures that the residence time is extended even at an increased flow rate and the components of the oxidation reaction used are reacted in such a way that an optimal product yield of the amine oxide (s) is achieved.
- reaction mixture is passed through two or more microreactors arranged in parallel in order to increase the throughput.
- the number and the arrangement of the channels in one or more microreactor (s) are varied in such a way that the residence time is lengthened, so that here, too, an optimal yield of the desired amine oxide is obtained at an increased flow rate is achieved.
- the residence time of the reaction solution in the microreactor is preferably ⁇ 15 hours, preferably ⁇ 3 hours, particularly preferably ⁇ 1 hour.
- the process according to the invention can be carried out in a very wide temperature range, which is essentially due to the temperature resistance of the materials used for the construction of the microreactor, if appropriate the residence zone, and also further components, such as, for example, connections and seals, and the physical properties of the solutions used and / or Liquids is limited.
- the process according to the invention is preferably carried out at a temperature of from -100 to +250 ° C., preferably from -78 to + 150 ° C., particularly preferably from 0 to +40 ° C.
- the process according to the invention can be carried out either continuously or batchwise. It is preferably carried out continuously.

- Pyridine and / or pyrimidine and / or pyrazine is very particularly preferably used as the nitrogen-containing aromatic heterocycle.
- Nitrogen-containing aromatic heterocycles also include aromatic compounds and / or their derivatives which have at least one monocyclic and / or polycyclic nitrogen-containing aromatic backbone or a corresponding partial structure, e.g. in the form of substituents. These nitrogen-containing, aromatic backbones or partial structures can also contain further heteroatoms, preferably oxygen and / or sulfur.
- Oxidizing agents are used. Preferably only one oxidizing agent is used at a time.
- the oxidizing agent is preferably at least one compound selected from inorganic and organic peroxides, hydrogen peroxide, mixtures of peroxo compounds with organic acids and / or inorganic acids and / or Lewis acids, organic peracids, inorganic peracids or dioxiranes or a mixture of at least two of these oxidizing agents.

- the selectivity of the reaction itself depends on a number of other parameters, e.g. the concentration of the reagents used, e.g. the temperature, the type of tertiary amine used or the nitrogen-containing aromatic heterocycle or the residence time. It is possible for a person skilled in the art to adapt the various parameters to the respective oxidation reaction in such a way that the desired amion oxide (s) is (are) obtained.
- the tertiary amines used and / or the nitrogen-containing aromatic heterocycles and the oxidizing agents are either themselves liquid or are in dissolved form. If these are not themselves already in liquid form, they must therefore be dissolved in a suitable solvent before the process according to the invention is carried out.

- the danger to humans and the environment from escaping chemicals is considerably reduced and it therefore leads to increased safety when handling hazardous substances.
- the oxidation of tertiary amines and nitrogen-containing aromatic heterocycles by the process according to the invention also enables better control of the reaction conditions, e.g. Reaction time and temperature than is possible in the conventional processes.
- the temperature can be individually selected and kept constant in each volume element of the system.
- the course of the oxidation reaction can be regulated very quickly and precisely in the process according to the invention.
