The effect of lithium chloride when used as an extractive agent for separating the azeotropic mixture composed of acetone and methanol, was determined. The methodology included the preparation of two mixtures with different acetone-methanol mass concentrations, below the azeotropic point: 85-15% and 75-25%. For each distillation carried out, lithium chloride was added in different measured dosages to determine its effect on the composition of the mixtures and the azeotropic point. The results suggested that a concentration of 2.3 moles of lithium chloride per kg of solution produced the greatest effect on the azeotropic point, considering the reflux manipulation and salt concentration. It was concluded that it is possible to separate this azeotropic mixture using lithium chloride as an extractive agent
