title: Non-isothermal thermal decomposition reaction kinetics of dimethylhexane-1,6-dicarbamate (HDC).
abstract: The thermal decomposition behavior and reaction kinetics of dimethylhexane-1,6-dicarbamate (HDC) were investigated by TG-DTG, DSC and IR techniques. It is shown that the decomposition process can be divided into 3 main stages and the first stage is the thermal decomposition reaction for HDC to dimethylhexane-1,6-diisocyanate (HDI). The main gaseous products of the decomposition are CO(2) and CH(3)OH. The kinetic parameters of the reaction for HDC to HDI are Ea=119.51 kJ mol(-1), lg(A/s(-1))=14.82, respectively. The kinetic equation is d(α)/d(t) = 10(15.12)(1-α)(3/2)e(-1.4375×10(4)/T).
