Definitions
- the present invention relates to the catalytic conversion of 2-hydroxy-
- HMTBN 4-methylthiobutanenitrile
- HMTBM 2-hydroxy-4-methylthiobutanamide
- the HMTBM thus obtained can be used for example for the production of 2-hydroxy-4-methylthiobutanoic acid (HMTBA) hydroxyanalogue of methionine, methionine being an essential amino acid widely used as a feed additive in animal nutrition.
- HMTBA 2-hydroxy-4-methylthiobutanoic acid
- HMTBN 2-hydroxy-4-methylthiobutyronitrile
- HMTBM 2-hydroxy-4-methylthiobutyramide
- HMTBA 2-hydroxy-4-methylthiobutanoic acid
- HMTBM resulting in the co-production of a very large amount of inorganic products difficult to exploit. Indeed, the catalytic activity of the strong mineral acids with respect to the HMTBN is such that all the introduced HMTBN is transformed very rapidly.
- the HMTBM produced may especially react with water to form HMTBA and ammonia. In the case of sulfuric acid, for example, it may react with the ammonia released to form ammonium sulphate which must then be treated.
- one of the proposed alternatives to this acidic hydration is an enzymatic process in which a nitrile hydratase, such as Rhodococcus (according to US 6 900 037 B2 and US Pat.
- WO 2002/070717 A2 for example, can transform HMTBN into HMTBM.
- the major disadvantage that penalizes this process lies in the difficulty of synthesize enzymes and extract them from the reaction medium after obtaining HMTBM.
- a solution proposed by the patent WO 2002/00869 for extracting the enzymes from the reaction medium is the use of insoluble granules in water containing the enzyme.
- the process for obtaining these granules is complicated and the catalytic activity of the enzymes in the granules is very much reduced.
- the low catalytic activity makes it possible to be very selective in HMTBM but the duration of the transformation reaction of HMTBN into HMTBM must be lengthened.
- Heterogeneous catalysis methods are also known.
- the hydration of HMTBN is carried out in the presence of a mass-based manganese oxide catalyst in a water / acetone mixture (450/150).
- the amount of manganese oxide used is 0.75 moles per 1 mole of cyanohydrin. It appeared that this reaction is difficult to reproduce because it is strongly related to the nature of the manganese oxide used. For example, in the presence of pyrolusite, no hydration reaction occurs.
- the hydration conditions of the HMTBN according to this patent do not appear easy to optimize to obtain a reproducible yield in the absence of secondary products.
- Patent FR 2,750,987 describes the hydration reaction of HMTBN or methylpropioaminonitrile cyanohydrin to the corresponding amide at low temperature (between 0 ° C. and 60 ° C.) in water in the presence of a catalyst with base of manganese oxide deposited on silica without any appearance of oxidation products on the sulfur atom.
- the molar ratio MnO 2 / HMTBN or MnO 2 / cyanohydrin of the methylthiopropioaminotrile is between 0.05 and 1.5.
- the weight ratio of the manganese oxide to the silica is preferably between 5 and 10%. It appears in the examples of this patent FR 2,750,987 that supporting manganese oxide on silica makes it possible to improve the selectivity of the reaction, but the small amounts of deposited active phase require long reaction times and / or Cyanhydrin very weak.
- the amount of water used in the reaction medium is not critical for the reaction but that if the reaction time is too long and / or the temperature too high, part of the HMTBM formed can react with the water of the reaction medium to form HMTBA and / or produce secondary products of condensation of HMTBM.
- the ammonia released induces an increase the hydrogen potential (pH) of the reaction medium which, at basic pH, causes the degradation of HMTBN which has not yet reacted and therefore an overall decrease in the production of HMTBM.
- patent EP 0 601 195 A1 which describes a process for producing HMTBA in three successive stages, the first of which consists in the catalytic conversion of HMTBN into HMTBM in the presence of a heterogeneous catalyst, preferably of manganese oxide. or alkali metal borate (sodium tetraborate), it is recommended to substitute a portion of the amount of water of the reaction medium with a water-soluble organic solvent, such as acetone or methanol, and add sulfuric acid to improve the selectivity of the reaction. According to this patent, sulfuric acid is added to improve the performance of the reaction but in very limited amounts to prevent the formation of ammonia. In the examples, the best yield of HMTBM obtained after 6 hours of reaction at 60 ° C. in the presence of manganese oxide and sulfuric acid in a water / acetone solvent is 89%.
- the state of the art shows that it is difficult to reconcile a strong catalytic activity for the hydration of HMTBN and a good selectivity in HMTBM.
- the best performances are described for catalysts based on manganese oxide.
- the best selectivities are obtained for manganese oxide supported on silica.
- the low levels of supported manganese oxides involve long reaction times or reaction media containing very low concentrations of HMTBN.
- One of the aims of the present invention is to provide an alternative to the methods described above but which does not have the disadvantages.
- a first object of the present invention is to provide a sufficiently active and selective solid catalyst to produce 2-hydroxy-4-methylthiobutanamide (HMTBM) from 2-hydroxy-4-methylthiobutanenitrile (HMTBN) in short reaction times. to limit the formation of unwanted by-products and without the addition of strong mineral acids so as not to produce inorganic waste and to prevent degradation of HMTBN.
