You place it in a closed container with a cold finger filled with ice (or dry ice, depending on how good your vacuum is) and you pump a vacuum on it until the hexane boils out. It is best known as the main ingredient of traditional mothballs Using a dynamic method, the solubilities of naphthalene in acetone, toluene, xylene, ethanol, heptane, and 1-butanol have been determined experimentally from (297.17 to 322.70, 291.35 to 334.65, 299.42 to 337.97, 304.26 to 339.76, 290.25 to 333.75, and 313.77 to 342.8) K, respectively.
