Definitions
- the present invention relates to a process for the preparation of dicarboxylic acids, in particular adipic acid (1,6-hexanedioic acid) by the action of nitric acid from the corresponding cyclic alcohols or ketones from the point of view of the number of atoms of carbon, in the presence of one or more nitrogen oxides in a large molar concentration in the reaction medium.
- dicarboxylic acids in particular adipic acid (1,6-hexanedioic acid) by the action of nitric acid from the corresponding cyclic alcohols or ketones from the point of view of the number of atoms of carbon, in the presence of one or more nitrogen oxides in a large molar concentration in the reaction medium.
- Adipic acid is an important intermediate, especially in the polymer field and more particularly for the preparation of polyamide, for example polyamide 6-6, or polyurethanes.
- polyamide 6-6 it is necessary to have a very high purity and this purity must already exist at the precursor stage, especially at the adipic acid stage.
- the requirement of maximum purity is particularly increased when adipic acid is to be used as raw material for the textile, electronics or food industry.
- the purity of the adipic acid used must be extremely high, both for the contents of by-products. only for metal residue levels. Indeed, the adipic acid must not contain impurities, especially metal, in a concentration greater than 1 ppm.
- Castellan et al. (Catalysis Today, 9 (1991) 237-322) proposes a broad review of the stakes related to adipic acid, in particular those related to its preparation by the action of nitric acid in the presence of oxidation catalysts such as vanadium and copper.
- adipic acid is conventionally synthesized by nitric acid oxidation of a mixture of cyclohexanone and cyclohexanol in the presence of oxidation catalysts such as copper and vanadium.
- nitric oxidation by nitric acid or by nitrogen oxides of compounds such as cyclohexanol generates nitrous vapors. These vapors are generated in an amount that is difficult to control and not very exploitable since it depends on the conditions for carrying out the reaction (temperature, nature and purity of the substrate to be oxidized, etc.). It is thus known to eliminate these vapors as and when they are formed, as disclosed in DE-767840.
- the present invention thus proposes to provide an improved process for carrying out the nitric oxidation reaction to produce dicarboxylic acids from cyclic alcohols or ketones having the same number of carbon atoms, in the presence of a quantity of significant nitrogen oxides, and that can solve all or part of the problems of the processes of the state of the prior art.
- the method according to the invention is a method, which makes it possible to overcome the presence of catalyst, and thus reduce the costs associated with the purification of the dicarboxylic acid obtained, especially with respect to the content of residual metals. It also avoids the costs associated with catalyst recycling operations. Thus, because of the absence of catalyst, the method according to the invention is also a more environmentally friendly process.
- the method according to the invention also makes it possible to consume or recycle the nitrogen oxides formed, to maintain a particularly high adipic acid selectivity, which is often of the order of or greater than 90%, especially greater than 95%, of obtain high yields of diacids which can reach or exceed 90%, especially 95% after 5 minutes, and allow low passage times reagents.
- This selectivity is obtained whatever the starting compound to be oxidized.
- the method according to the invention makes it possible to achieve the above-mentioned selectivity values for adipic acid from cyclohexanol, cyclohexanone or a mixture of the two compounds.
- the method of the invention also allows implementation at lower temperatures than known methods.
- the process according to the invention also makes it possible to start or conduct the reaction in the presence of cyclohexanone alone during the preparation of adipic acid.
- the process according to the invention can also be a continuous or batch process for the preparation of dicarboxylic acids.
- An object of the present invention is therefore to provide a process for the preparation of a dicarboxylic acid of formula (I), in which n represents an integer ranging from 1 to 9, by the action of nitric acid, in the presence of one or more nitrogen oxides in a molar concentration in the reaction medium of greater than 2.5 mmol per kg of reaction medium, on compounds of formula (II) or (III) in which n represents the same integer as in formula (I)
- the process uses a mixture of the compounds of formulas (II) and (III).
- the process according to the invention is carried out for the preparation of a compound of formula (I) for which n represents 2, 3, 4, 5 or 9, preferably 3 or 9 in particular n represents 3.

- the process uses one or more nitrogen oxides chosen from NO, NO 2 , N 2 O 3 , N 2 O 4 , N 2 O 5 , NO 3 , N 2 O 6. , N 4 0, and mixtures thereof preferably from NO and N0 2.
- the process uses one or more nitrogen oxides in an amount greater than 30 mmol of nitrogen oxides per kg of reaction medium.

- nitrogen per kg of reaction medium even more preferably ranging from 180 to 650 mmol of nitrogen oxides per kg of reaction medium.
- the amount of nitrogen oxides added ranges from 300 to 400 mmol / kg of reaction medium.
- the method implements a molar ratio R corresponding to the number of moles of nitrogen oxides added to the reaction medium relative to the number of moles of substrate to be oxidized (compounds (I) and / or (II)) which is greater than or equal to 0.5, in particular greater than or equal to 1, preferably greater than or equal to 1, 5 and even more preferably greater than or equal to 2. From a higher molar ratio or equal to 0.5, the selectivity to dicarboxylic acid is improved. This effect is all the more important since the ratio R is greater than or equal to 1, and in particular to 1, 5.
- the upper limit value is, for economic and implementation reasons, less than or equal to 50, preferably less than or equal to 30, in particular less than or equal to 10.
