| Abstract: | Water, formic acid and acetic acid constitute a ternary constant boiling mixture of the saddle type. Formic acid(cont.≥90%) and acetic acid(cont.>99%) can be obtained by separation via dehydration through azeotropic distillation followed by vacuum distillation. Through analog computation, the number of theoretical plates has been worked out as well. |
