    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in a short retention time and in a good yield by dehydrating a specific oxime in the presence of a specific heterogeneous catalyst in a gaseous or liquid phase at a temperature within a specified temperature range. SOLUTION: This method for producing an aliphatic unsaturated nitrile of formula II [R, R and R are each a 1-20C alkyl or the like; (n) is 0-20] comprises hydrating (A) an oxime of formula I (preferably citral oxime) in the presence of (B) (i) a heterogeneous catalyst comprising an oxide, carbide or nitride carrier (preferably aluminum trioxide) doped with a basic oxide and/or hydroxide [preferably an alkali(ne earth) metal oxide or the like] or a compound capable of being converted into one of the compounds under the reaction conditions, preferably in an amount of 0.1-50 wt.% (converted into the oxide) or (ii) a heterogeneous catalyst comprising a basic oxide, at a temperature of 150-300 deg.C in a gaseous or liquid phase under a pressure of preferably 0.5-5 bars.

    Abstract: An improved process is disclosed for preparing α,β-diaminoacrylnitriles having the general formula (I) R?3R2NC(R1)=C(NR2R3¿)CN, in which R1 stands for hydrogen, substituted or non-substituted aliphatic residues with 1 to 30 carbon atoms, cycloaliphatic residues with 3 to 8 ring members or aromatic, heteroaromatic or araliphatic residues with 7 to 12 carbon atoms; R?2 and R3¿ are the same or different and stand for hydrogen or an aliphatic residue with 1 to 15 carbon atoms, a cycloaliphatic residue with 3 to 8 ring members or an aromatic, heterocyclic or araliphatic residue with 7 to 12 carbon atoms, or residues R?2 and R3¿ may be bound together into a 5- or 6-membered ring that may also carry another heteroatom. In this process, component (A) is reacted with components (B), (C) and (D) in any desired order. (A) is an α-dicarbonyl compound having the general formula R1COCHO, in which R1 has the above-said meaning, or a reactive derivative of said carbonyl compound. (B) is a salt of sulphurous acid, sulphur dioxide or a sulphur dioxide-releasing reactive. (C) is an amine having the general formula HNR2R3 or an aliphatic diamine having the general formula R3HN-(CH¿2?)n-NHR?3¿, in which the alkylene chain may also bear an R1 substituent having, like R3, the above-said meaning and n equals 2 or 3, or derivatives that are converted into amine or diamine in reaction conditions. (D) is liquid or gaseous hydrocyanic acid or a hydrocyanic acid-releasing reactive. The reaction is carried out with at least 3.5 equivalent alkali compounds per mole of component A. The most part of the alkaline compound consists of potassium compounds and at least one alkali equivalent is added as a free alkaline lye, provided that the proportion of potassium equivalents be sufficiently high for all inorganic salts to remain practically completely in solution at the end of the reaction.
