2-Naphthoic acid Usage And Synthesis

Chemical Properties

Colorless solid

Purification Methods

Crystallise the acid from EtOH (4mL/g), aqueous 50% EtOH or Me2CO (m 185-186o). Dry it at 100o. The acid chloride has m 52-52o (from *C6H6/pet ether) and b 160-162o/11mm [Hersberg & Carson Org Synth Coll Vol III 629 1955], the amide has m 192o (from EtOH), and the N-Methyl amide has m 109-109.5o (form *C6H6). [Beilstein 9 H 656, 9 III 3174, 9 IV 2402.]
