1,6-Dihydroxynaphthalene Usage And Synthesis

Chemical Properties

Beige powder

Definition

ChEBI: Naphthalene-1,6-diol is a naphthalenediol.

Synthesis

1,6-Naphthalenediol [575-44-0], mp 138℃, is synthesized by caustic fusion of naphthalene1,6-disulfonic acid at 330 C. It couples with diazotized anilines to form disazo and trisazo derivatives.

Purification Methods

Crystallise it from *benzene or *benzene/EtOH after treatment with charcoal. [Beilstein 6 IV 6557.]
