I whakamahia hei hanga mai i te β-naphthylamine.Na te kaha o te carcinogenicity o te β-naphthylamine, kua whakakorehia tenei tikanga whakaputa, a inaianei ka whakamahia te waikawa 2-naphthylamine-1-sulfonic hei rauemi mata hei whakaputa i te waikawa J.I muri i te sulfonation me te hydrolysis, ka whiwhi te 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium salt (amino J acid), ka whakakorehia, ka whakakotahihia e te alkali me te waikawa.I whiwhihia te waikawa J ma te sulfonation me te ngongo o te waikawa pungatara, te hauwai, te mimiti, te horoi, te wairewa alkali me te horoi waikawa.Ka memeha te tote konutai i roto i te wai, ka whakaatu i te korikori kahurangi.Ka whakawerahia ki te wairewa trichloride ferric hei hanga i te rerenga parauri-pango.
Taonga matū
1. Ko te waikawa J i whakamahana tahi me te wairewa ferric chloride kia puta ai he parapara parauri pouri;te konupūmā pūhaumāota ki te hanga i te kowhai parauri kowhai;Ko te tote konutai i whakarewahia ki roto i te wai ka whakaatu i te korikori kikorangi.
2. A ape i te tango i te puehu o tenei hua me te karo i te pa ki nga kanohi me te kiri.
3. paihana.I whakawhiwhia ki nga kiore LD50:11500mg/kg.Ka whakamahia nga mea mata paitini, tino kino ranei penei i te waikawa 2-aminonaphthalene sulfonic, te waikawa pungatara whakakoi me te houra caustic i roto i te hanga.
Nga tono
Waikano takawaenga.Ka whakamahia te nuinga ki te whakarite i te lotus matomato R, te FRL puru tere, te pungarehu tere 2BL, te tote parahi tika puru 2R, te papura atete waikawa tika, te mawhero tika, te waikano parahi tika navy, te tere puru B2R, te jujube GB, me he ngangana tauhohenga, he karaka, he karaka kanapa X-GN, he hina, he tarutaru kaakaariki, he whero parauri me etahi atu tae.Ka whakamahia hoki hei whakarite i te waikawa J rua, te waikawa ngangana me te waikawa phenyl J.
te rokiroki me te takai
Nga Taipitopito mokete: 25kg/peeke
Me hiri me te tiaki i te marama.Rokiroki i roto i te whare maroke, ma kia kore e pa ki te ra me te ua.Ina tuuhia, me piki te waha o te pouaka (pahu) kia kore ai e pakaru te hua.
etahi ingoa:J waikawa; 2-amino-5-naphthol-7-sulfonic acid;6-amino-1-naphthol-3-sulfonic acid
