| Abstract: | Continuous esterification process for producing tri(2-ethyl)hexyl trimellitate (TOTM) by using 2-ethylhexanol (EH) and trimellitic anhydride (TMA) as raw materials and tetra(iso-propyl) titanate as catalyst was studied. Based on reaction kinetics, the process flow diagram of continuous esterification and reaction conditions were determined. The conversion of trimellitic anhydride was over 99. 98%. The stripping column was designed to remove water in recycle procedure and the optimum operation condition was obtained. |
