Phoenix Equipment Corporation has this used Adiponitrile (ADN) plant immediately available.
ADN is produced by the electrohydrodimerisation (EHD) of acrylonitrile (AN).
The dimerisation of AN is by direct electrolysis in the presence of a recirculated aqueous electrolyte solution.
The basic reaction equation is given below:
2 CH2CHCN + 2 e- + 2 H+ --> NCCH2CH2CH2CH2CN
The products are adiponitrile (ADN) and hexamethylenediamine (HMD), both of which are intermediates in the manufacture of Nylon salt.
