Application of Computer Simulation Technology in Chemical Synthesis of Resin Material ADH

Abstract

We use Aspen software to simulate the whole synthetic process of adipic dihydrazide (ADH) using methanol. The whole process is divided into esterification reaction and hydrazide reaction. In the esterification reaction, distillation adopts two-step evaporation, which can significantly reduce the temperature and energy consumption. The distillation product dimethyl adipate enters the next reaction module, indicating that esterification reaction can achieve 100% apparent yield in the hydrazide reaction, 2kmol/h 80% hydrazine hydrate can be used to achieve recycling of raw materials. The experimental results show that the ADH synthesis with methanol as the raw material simulated by Aspen is consistent with the experiment data, proving the effectiveness of the simulation.
