2. 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.

4. Adiponitrile is the organic compound with the formula (CH2)4(CN)2. This dinitrile,
a viscous, colourless liquid, is an important precursor to the polymer nylon-6,6.
One major process route is electrosynthesis, starting from acrylonitrile, which is
dimerized: 2 CH2=CHCN + 2 e− + 2 H+ → NCCH2CH2CH2CH2CN

6. Global adiponitrile market size
was estimated at 1.4 million
mt in 2018 and the market size
will reach 1.5 million mt in
2024, with a CAGR of 1.2%.
