One such mixture consists of α-naphthol, m.p. 94 ºC, and p-toluidine, m.p. 43 ºC. The A:B complex has a melting point of 54 ºC, and the phase diagram displays two eutectic points, the first at 50 ºC, the second at 30 ºC. Molecular complexes of this kind commonly have a 50:50 stoichiometry, as shown, but other integral ratios are known. Pour the eluting solvent, a 99/1 mixture of Ethyl Acetate/Glacial Acetic Acid, into the beaker to a depth of approximately 1 cm. Place the prepared TLC plates in the developing chamber.
