2-Nitroso-1-naphthol Chemical Properties,Usage,Production

Chemical Properties

yellow-greenish to yellow-brownish powder

General Description

2-nitroso-1-naphthol helps in the extraction of cobalt ion as it is used as a selective complexing agent. It is used in the separation and preconcentration of Th(IV), Ti(IV), Fe(III), Pb(II) and Cr(III) by solid phase extraction.

Safety Profile

Moderately toxic by ingestion. Many nitroso compounds are carcinogens. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits toxic fumes of NOx. See also NITROSO COMPOUNDS.

Purification Methods

Purify the naphthol by recrystallisation from pet ether (b 60-80o) or by dissolving it in hot EtOH, followed by successive addition of small volumes of water (m 158o dec). It also crystallises from *C6H6 or H2O. Crystallisation from *C6H6/pet ether gives m (106-109 o, also 109.5o). It has max at 274.5 and 382nm (CHCl3). It complexes with metals.
