Industrial products are brown liquid or gray paste with blue fluorescence. After sulfonation of naphthalene with fuming sulfuric acid and nitration with mixed acid, magnesium salt of 2-nitro-4,8-naphthalenesulfonate was obtained by separating isomer with magnesium salt (MgCO3), adding sodium hydroxide to make sodium salt, and then reducing.
