The experimental results showed that with a fixed total amount of AN and ADN, more oligomers, i.e. ADN and trimer, were produced than PN initially. Along the reaction time, AN concentration decreased, oligomers production rate slowed down and PN production rate increased. A higher AN ratio in the electrolyte gave more initial oligomers than lower AN ratio did. If AN ratio was too low, hydrogen evolution became the main reaction.
When AN concentration was fixed at high values, concentration ratio of AN to ADN did not affect the production rate of ADN, but higher ratio of AN to ADN resulted in higher AN conversion and trimer production rates. Adding an appropriate amount of ADN into an initial electrolyte could increase the selectivity of ADN. When AN concentration was fixed at low values, the addition of ADN were not favor for the oligomerization, but resulted in an increase in the productions of PN and hydrogen. Experiments also showed that the addition of ADN could reduce the volatilization of AN. When AN was fixed at high concentrations, current efficiency always remained higher than 90%, which meant that high AN concentration could suppress hydrogen generation.
