- Summary
- 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
- Technology Benefits
- 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
- Technology Application
- 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
- Detailed Technology Description
- 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
