text: If aniline to be purified is from vapor phase process, according to prior art its in fact through twice condensation: first, the reaction product obtaining with gas form is total condensation substantially, remove the organic phase that water distillation obtain, that is: required product (i) condensation, (ii) evaporation and (iii) condensation again, this is energy and device very dense thermal load type and that cause aniline.
