응용 분야 · 2건

용도Naphthalene-2-sulfonic acid is used in making direct dyes, reactive des and employed as dye and agrochemical intermediates.

일반 설명The fluorescence of 2-naphthalenesulfonic acid (NSA) is effectively quenched by colloidal silver via photoinduced interfacial electron transfer from the excited singlet of NSA to silver. Adsorption behavior of NSA on a conventional macroporous resin Amberlite XAD4 and hypercrosslinked resins NDA101 and NDA100 has been investigated.

제조 방법 · 1건

Naphthalene-2-sulfonic acid is prepared by sulfonation of naphthalene. Step: With naphthalene as raw material, 98% sulfuric acid is used as sulfonating agent, and it is obtained by sulfonation at 160-166 ℃. During the sulfonation process, a small amount of α-naphthalenesulfonic acid by-product is generated. By heating, the unstable α-naphthalenesulfonic acid can be hydrolyzed at 140-150 °C to remove the sulfonic acid group, and become naphthalene and sulfuric acid. Naphthalene can be blown out. During the hydrolysis of naphthalene, a small amount of lye should be added to neutralize part of the sulfuric acid. It also acts with naphthalenesulfonic acid to form β-naphthalenesulfonic acid sodium salt crystals, which can be filtered to obtain the finished product of Naphthalene-2-sulfonic acid.
