    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.

    Abstract translation: 公开了用于制备具有通式（I）R 3 R 2 NC（R 1）= C（NR 2 R 3）CN的α，β-二氨基丙烯腈的改进方法，其中R 1代表氢，取代或未取代的脂族残基， 30个碳原子，具有3至8个环成员的环脂族残基或具有7至12个碳原子的芳族，杂芳族或芳脂族残基; R 2和R 3相同或不同，代表氢或具有1至15个碳原子的脂族残基，具有3至8个环成员的脂​​环族残基或具有7至12个碳原子的芳族，杂环或芳脂族残基， 或者残基R 2和R 3可以一起结合成也可带有另一个杂原子的5-或6-元环。 在该方法中，组分（A）以任何所需顺序与组分（B），（C）和（D）反应。 （A）是具有通式R 1 COCHO的α-二羰基化合物，其中R 1具有上述含义或所述羰基化合物的反应性衍生物。 （B）是亚硫酸，二氧化硫或释放二氧化硫的活性成分的盐。 （C）是具有通式HNR2R3的胺或具有通式R3HN-（CH2）n-NHR'3的脂族二胺，其中亚烷基链还可以带有R1取代基，其具有如R3， 上述含义和n等于2或3，或在反应条件下转化为胺或二胺的衍生物。 （D）是液态或气态氢氰酸或释放氢氰酸的反应性物质。 该反应用每摩尔组分A至少3.5当量碱性化合物进行。碱性化合物的大部分由钾化合物组成并且至少一种碱当量以游离碱性碱液形式加入，条件是钾当量 对于所有无机盐而言足够高以在反应结束时实际上完全保留在溶液中。

    Abstract: An improved process is disclosed for preparing alpha , beta -diaminoacrylnitriles having the general formula (I) R R NC(R )=C(NR R )CN, in which R 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 and R 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 and R 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 alpha -dicarbonyl compound having the general formula R COCHO, in which R 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 HNR R or an aliphatic diamine having the general formula R HN-(CH2)n-NHR , in which the alkylene chain may also bear an R substituent having, like R , 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.
