Abstract:
The synthesis of toluene-2,4-dicarbamate (TDC) from 2,4-diamino toluene and dimethyl carbonate is a complex reaction system.The reaction heat,Gibbs free energy change and equilibrium constant of the reactions are calculated by methods of group contribution.The effect of methanol content in the raw material on the yield of TDC is investigated.The comparison among the estimated data,literature data and experimental data show that the results of estimation are reasonable,and the results are very important for experimental research and scale-up of the process.
