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.
Waiwai kemika
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.

Waiwaena waena.Hoʻohana nui ia no ka hoʻomākaukau ʻana i ka lotus ʻōmaʻomaʻo pololei R, pololei wikiwiki uliuli FRL, pololei wikiwiki lehu 2BL, pololei keleawe paʻakai uliuli 2R, pololei ʻakika kūpaʻa poni, pololei ʻulaʻula, pololei keleawe kala navy, wikiwiki polū B2R, pololei jujube GB, pū kekahi e like me ka ʻulaʻula hoihoi, ka ʻalani, ka ʻalani ʻālohilohi X-GN, ka hina, ka mauʻu ʻōmaʻomaʻo, ka ʻulaʻula ʻulaʻula a me nā mea pena ʻē aʻe.Hoʻohana pū ʻia e hoʻomākaukau i ka ʻakika J pālua, ka ʻakika ʻulaʻula a me ka waikawa phenyl J.
ka waiho ʻana a me ka hoʻopaʻa ʻana

Pono e hoʻopaʻa ʻia a pale ʻia mai ka mālamalama.E mālama i loko o kahi hale maloʻo a maʻemaʻe e pale aku i ka lā a me ka ua.Ke kau ʻia, pono e piʻi ka waha o ka pahu (pahu) e pale i ka leakage o ka huahana.
