技术优势

Effective biocatalytic production process of aliphatic linear a,w-dinitriles
Applicability for synthesis of adiponitrile already proven (>99% conversion, up to 80% yield)
Dialdoximes as readily available starting materials available from dialdehydes
Mild reaction conditions and excellent selectivity
Avoiding hydrogen cyanide as toxic reagents

技术应用

Aliphatic, linear dinitriles are of high interest in the field of polymer chemistry due to their easy transformation into diamines.The described technology enables a safe, fast chemical production of aliphatic linear
dinitriles, e.g., adipodinitrile, with a long-term perspective for a cost competitive and
sustainable technology compared to today´s already existing production routes

详细技术说明

The present invention focuses on a biocatalytic production process to aliphatic linear
dinitriles, which avoids the need of hydrogen cyanide and leads to the desired products
with excellent selectivity as in general no side-products were observed. In addition, this
biocatalytic process can be conducted under mild reaction conditions. The innovative
production process starts from a simple condensation of a dialdehyde raw material with hydroxylamine. The formed
dialdoxime is then transformed via a biocatalytic dehydration to the dinitrile
