Hana ʻia mai ka β-naphthylamine.Ma muli o ka ikaika o ka carcinogenicity o ka β-naphthylamine, ua hoʻopau ʻia kēia ʻano hana hana, a i kēia manawa ua hoʻohana ʻia ka 2-naphthylamine-1-sulfonic acid i mea maka no ka hana ʻana i ka waikawa J.Ma hope o ka sulfonation a me ka hydrolysis, ua loaʻa ka 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium paʻakai (amino J acid), a laila neutralized, hoʻohui ʻia e ka alkali a me ka acidified.Ua loa'a mai ka J waika ma ka sulfonation me ka sulfuric acid fuming, hydrolysis, absorption, holoi, alkali solution and acidizing washing.Hoʻoheheʻe ka paʻakai sodium i ka wai a hōʻike i ka fluorescence polū.Hoʻopili pū ʻia me ka solution ferric trichloride e hana i ka ua ʻeleʻele-ʻeleʻele.

1. J waika i hui pu ia me ka ferric chloride solution e hana ai i ka eoke eleele eleele;ʻo ka calcium chloride e hoʻoheheʻe i ka ʻeleʻele melemele;ʻO ka paʻakai sodium kumu i hoʻoheheʻe ʻia i ka wai hōʻike i ka fluorescence polū.
2. E hō'ole i ka hanu'ana i ka lepo mai kēia huahana a pale i ka pili'ana me nā maka a me ka'ili.
3. mea make.Hāʻawi ʻia nā ʻiole waha LD50:11500mg/kg.Hoʻohana ʻia nā mea ʻawaʻawa a i ʻole nā mea ʻona e like me ka 2-aminonaphthalene sulfonic acid, fuming concentrated sulfuric acid a me ka soda caustic i ka hana ʻana.
