Definitions
- Vazquez-Tato Synlett 1993, 506, discloses the use of microwaves as a heat source for the preparation of amides from carboxylic acids and arylaliphatic amines via the ammonium salts. The syntheses were carried out on a mmol scale.
- the inhomogeneity of the microwave field caused by localized overheating of the reaction mixture, caused by more or less uncontrolled reflections of the microwaves irradiated into the microwave oven on the walls thereof and the reaction mixture in the commonly used multimode microwaves causes problems in scale-up.
- the microwave absorption coefficient of the reaction mixture which often changes during the reaction, presents difficulties with regard to a reliable and reproducible reaction.
- R 3 is hydrogen or an optionally substituted alkyl group having 1 to 4 carbon atoms, with at least one amine of the formula II
- Another object of the invention are carboxylic acid amides with a low metal content, prepared by reacting at least one carboxylic acid of formula I.
- R 3 is hydrogen or an optionally substituted alkyl group having 1 to 4 carbon atoms, with at least one amine of the formula
- R 3 is preferably a saturated alkyl radical having 1, 2, 3 or 4 C atoms. This can be linear or branched.
- the carboxyl group can be bonded to a primary, secondary or, as in the case of pivalic acid, tertiary C atom.
- the alkyl radical is unsubstituted
- the alkyl radical carries one to nine, preferably one to five, for example two, three or four further substituents.
- substituents may be, for example, C 1 -C 4 alkoxy such as, for example, methoxy, ester, amide, carboxyl, cyano, nitrile, nitro and / or C 5 -C 2 0 aryl groups, for example phenyl groups, with the proviso the substituents are stable under the reaction conditions and do not undergo side reactions such as elimination reactions.
- the C 5 -C 2 o-aryl groups may in turn carry substituents.
- R 1 and / or R 2 are independently an optionally substituted C 6 -C 2 aryl group or an optionally substituted heteroaromatic group having 5 to 12 ring members.
- R 1 and / or R 2 independently of one another are an alkyl radical interrupted by heteroatoms. Particularly preferred heteroatoms are oxygen and nitrogen.
- R 1 and / or R 2 independently of one another are preferably radicals of the formula III (III)
- Cavity resonator directed. It has a maximum in the area of the central axis of symmetry and decreases to the lateral surface to the value zero. This field configuration is rotationally symmetric about the central axis of symmetry.
- the length of the resonator is selected relative to the wavelength of the microwave radiation used.
- N is preferably an integer from 1 to 200, particularly preferably from 2 to 100, in particular from 4 to 50 and especially from 3 to 20, for example 3, 4, 5, 6, 7 or 8.
- a very high efficiency is achieved in utilizing the microwave energy radiated into the cavity resonator, which is usually more than 50%, often more than 80%, partly over 90% and in special cases more than 95%, for example over 98% of the radiated microwave power and thus provides economic as well as environmental advantages over conventional manufacturing methods as well as prior art microwave methods.
- the microwave irradiation is carried out in the presence of acidic solid catalysts.
- the solid catalyst is suspended in the optionally mixed with solvent ammonium salt or advantageously the optionally with solvent-added ammonium salt passed through a fixed bed catalyst and exposed to microwave radiation.
- Suitable solid catalysts are, for example, zeolites, silica gel, montmorillonite and (partially) crosslinked polystyrenesulphonic acid, which may optionally be impregnated with catalytically active metal salts.
- Suitable acidic ion exchanger based on polystyrene sulfonic acids that can be used as solid phase catalysts are for example available from the company Rohm & Haas under the trademark Amberlyst ®.
- reaction mixture is preferably between 2 and 95 wt .-%, especially between 5 and 90 wt .-% and in particular between 10 and 75 wt .-%, such as between 30 and 60 wt .-%.
- the reaction is carried out solvent-free.
- the reaction is carried out in a pressure-resistant inert tube, wherein the water of reaction forming and optionally starting materials and, if present, solvents lead to a pressure build-up.
- the excess pressure can be used by relaxation for volatilization and separation of water of reaction, excess starting materials and, if appropriate, solvents and / or for cooling the reaction product.
- the water of reaction formed is after cooling and / or relaxation by conventional methods such as phase separation, distillation stripping, flashing and / or absorption separated.
- reaction mixture was placed in the reaction tube under such a working pressure, which was sufficient to all educts and products or
- the reaction mixture contained 85 ppm of dissolved iron and had a black-brown color.
