Purification Methods

Commercial material can contain up to 2% of poly-1-vinylnaphthalene. Fractionally distil it under reduced pressure using a spinning-band column, dry it with CaH2 and again distil it under vacuum. Store it in sealed ampoules in a freezer. It has max (cyclohexane) at 210 and 320nm. The picrate has m 105-106o. [Beilstein 5 H 585, 5 III 1773, 5 IV 1833.] It is an irritant.
