1,7-Dihydroxynaphthalene Chemical Properties,Uses,Production
Chemical Properties
Yellowish to white powder. 1,7-Naphthalenediol [575-38-2], mp 181℃, is prepared by caustic fusion of 2-hydroxynaphthalene-8-sulfonic acid at 300℃ or by acid desulfonation of 2,8-dihydroxynaphthalene-6- sulfonic acid. It couples with diazotized anilines to form monoazo and disazo derivatives.
Uses
The preparation of 1,7-Dihydroxynaphthalene and its prompt characterization from its NMR data and peculiarities. Removal of dihydroxynaphthalenes from aqueous solution with the aid of an oxidoreductase polyphenol oxidase and biopolymer chitosan.
Application
1,7-Dihydroxynaphthalene is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.
