Definitions
- the present invention relates to a method of manufacturing diaminomaléonitril ⁇ .
- Diaminomaléonitriie (DA N) is known to be a precursor for the synthesis of nitrogenous rings such as imidazotes, pyrazines and purines. But recently the DAMN has proved to be a precursor for the synthesis of new lithium salts having interesting properties for improving the performance of Li-ion batteries (WO 2010/023413),
- Diaminomaléonitriie is conventionally obtained by polymerization of cyanhydric acid (HCN) using different types of catalysis.
- GB 1325620 describes the preparation of DAMN by tetramerization liquid phase HCN at a temperature between ⁇ ⁇ 40 ° C and below 0 ° C in the presence of a basic catalyst and at least one catalyst selected from-eo cyanogen and diiminosuccinonitrile.
- US Pat. No. 3,839,406 describes a process for the preparation of the DAMN comprising the following steps: (a) mixing at ambient temperature an alkaline catalyst chosen from sodium cyanide and potassium cyanide, in a solvent chosen from hexa-methyl-phosphoramide and hexa-ethylphosphoramide, (b) progressive addition of HCN and continued agitation of the reaction medium! for six hours with a molar ratio cyanide aleaisn / HCN less than 0.25, (c) dilution of the solution with hot water and (d) removal of a blackish amorphous polymer by flitration.
- an alkaline catalyst chosen from sodium cyanide and potassium cyanide
- the document CA 1000297 describes a process for the manufacture of diaminomalonitriy by polymerization of HCN in the presence of a compound chosen from oxides, hydroxides and cyanides of alkaline earth metals in a solvent chosen from n- methylpyrrolidone, dimethylsulfoxide and dimethylformamide.
- the starting reagent is hydrocyanic acid, which is a very toxic gas and whose use is highly regulated, which therefore limits access to the DAMN.
- the growing market for Li-ion batteries and interesting properties of the lithium salts synthesized from the DAMN will induce a high demand of DA N,
- the present invention relates to a process for producing diaminomalononitrile from a cyanohydrin ketone according to reaction 1.
- R and R ' identical or different, representing a linear or branched alkyl chain having from 1 to 5 carbon atoms.
- the process according to the present invention comprising at least one reaction step (1) can be carried out in the presence of a catalyst.
- the catalyst may be selected from the group consisting of inorganic or organic bases of which pK A is from 1 to 14, alkali or alkaline earth metal oxides and Lewis acids.
- Oxides that may be mentioned include potassium oxide, sodium oxide or calcium oxide. Silicon oxide may also be suitable.
- Lewis acids examples include trialkylaluminum, boron trialkyl or pentaalkylphosphorus.
- reaction can be carried out in the presence of an aprotic solvent.
- aprotic solvent mention may be made of nitriies, hexa-alkylphosphoramide, dimethylformamide, dimethylsulfoxide, toluene or oxyfene.
- the additives may also be present in the reaction medium.
- additives mention may in particular be made of mercaptans.
- the reaction temperature may be from -50 to 200 ° C, preferably from -20 to 150 ° C.
- reaction time can vary within wide limits. It is preferably between 1 and 96 hours, advantageously 1 and 72 hours. According to one embodiment of the process of the present invention, reaction 1 can be carried out in the presence of HCN according to the following scheme,
- the molar ratio of HCN / ketone cyanohydrin y / x may be between 0.001 and 2.5, preferably between 0.005 and 2.
- the molar ratio of the amount of catalyst to the total amount of reagents involved is preferably between 0.01 and 1,
- the method according to the present invention may further comprise at least one step of recovering the ketone formed as a co-product.
- the process may also include at least one catalyst recovery step.
- the process may also include a step of recovering excess cyanohydrin ketone.
- the process may comprise a step of purifying the diaminomaleonitile such as, for example, recrystallization or treatment with activated charcoal.
- the ketone cyanohydrin is acetone cyanohydrin.
- Example 1 illustrates the invention without limiting it.
