ABSTRACT:
In the fractional distillation of multicomponent mixtures where freezing of a component is encountered in the overhead condensing section and/or product decomposition is encountered at reboiling temperatures, these problems are obviated by carrying out the distillation in the presence of an added inert liquid which is somewhat more volatile than the component having a tendency to freeze. In one embodiment, the reaction effluent obtained in the production of thiophenol is subjected to fractional distillation wherein the distillation is carried out in the presence of a light hydrocarbon having a lower boiling point than an aromatic such as benzene so as to prevent freezing of benzene in the overhead condenser and at the same time lower the reboiler temperature to minimize thiophenol product decomposition.
