Lunelli B. Single pot sequential crystallization-distillation as a new purification procedure. In: Inorganica Chimica Acta, vol. 360 (3) pp. 1217 - 1220. Elsevier B.V, 2007.
A new purification procedure exploiting the simultaneous presence of a solid, liquid, and gas phase in a low surface area system is proposed and discussed. The assumptions of vanishingly low diffusion coefficients in the solid phase and that of the presence of a single "effective impurity" allow to plan the sequence of operations starting from the knowledge of just the melting and boiling points of the substance to be purified and of those of the "effective impurity". Examples and results are presented.
