Amapangidwa kuchokera ku β-naphthylamine.Chifukwa cha carcinogenicity yamphamvu ya β-naphthylamine, njira yopangira iyi yatha, ndipo tsopano 2-naphthylamine-1-sulfonic acid imagwiritsidwa ntchito ngati zopangira kupanga J acid.Pambuyo pa sulfonation ndi hydrolysis, 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium mchere (amino J acid) inapezedwa, yomwe kenako imachotsedwa, imasakanikirana ndi alkali ndi acidified.J asidi anapezedwa ndi sulfonation ndi fuming sulfuric acid, hydrolysis, mayamwidwe, kutsuka, alkali njira ndi kutsuka acidizing.Mchere wa sodium umasungunuka m'madzi ndikuwonetsa buluu fluorescence.Amatenthedwa ndi ferric trichloride solution kuti apange mvula yabulauni-wakuda.
Chemical katundu
1. J asidi wotenthedwa ndi ferric chloride yankho kuti apange mpweya woderapo;calcium chloride kupanga chikasu bulauni precipitate;m'munsi sodium mchere kusungunuka m'madzi anasonyeza blue fluorescence.
2. Pewani kutulutsa fumbi la mankhwalawa ndipo pewani kukhudzana ndi maso ndi khungu.
3. chakupha.Makoswe anapatsidwa pakamwa LD50:11500mg/kg.Zopangira poizoni kapena zowononga kwambiri monga 2-aminonaphthalene sulfonic acid, fuming concentrated sulfuric acid ndi caustic soda zimagwiritsidwa ntchito popanga.
Mapulogalamu
Utoto wapakati.Amagwiritsidwa ntchito pokonzekera mwachindunji wobiriwira lotus R, mwachindunji kudya buluu FRL, mwachindunji mofulumira phulusa 2BL, mwachindunji mkuwa mchere buluu 2R, mwachindunji asidi kugonjetsedwa wofiirira, pinki mwachindunji, mwachindunji mkuwa utoto navy, kudya buluu B2R, mwachindunji jujube GB, komanso monga zotakasika wofiira, lalanje, brilliant lalanje X-GN, imvi, udzu wobiriwira, wofiira bulauni ndi utoto ena.Amagwiritsidwanso ntchito popanga double J acid, scarlet acid ndi phenyl J acid.
kusunga ndi kulongedza
Phukusi zambiri: 25kg / thumba
Iyenera kusindikizidwa ndikutetezedwa ku kuwala.Sungani m'nyumba yowuma, yaukhondo kuti musamakhale ndi dzuwa ndi mvula.Akayikidwa, pakamwa pa bokosi (ng'oma) azikhala m'mwamba kuti asatayike.
ena dzina: J asidi;2-amino-5-naphthol-7-sulfonic asidi;6-amino-1-naphthol-3-sulfonanic acid
