Fa'aaoga e fai mai le β-naphthylamine.Ona o le malosi o le carcinogenicity o le β-naphthylamine, o lenei auala gaosiga ua faʻaumatia, ma o le taimi nei o le 2-naphthylamine-1-sulfonic acid o loʻo faʻaaogaina e fai ma mea mata e maua ai le J acid.Ina ua maeʻa le sulfonation ma le hydrolysis, na maua ai le 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium salt (amino J acid), lea na faʻafefeteina, faʻafefiloi e le alkali ma faʻafefeteina.J acid na maua mai i le sulfonation ma fuming sulfuric acid, hydrolysis, absorption, fufuluina, alkali solution ma acidizing fufulu.O le masima sodium e solo i totonu o le vai ma faʻaalia ai le fluorescence lanumoana.E fa'avevela fa'atasi ma le vaifofo ferric trichloride e fai ai le timu enaena-uliuli.
meatotino tau vailaau
1. J acid fa'afefiloi fa'atasi ma le ferric chloride solution e fa'atupu ai le enaena pogisa;calcium chloride e fa'atupu ai le pa'u samasama enaena;masima sodium fa'avae fa'amuta i le vai na fa'aalia ai le fluorescence lanumoana.
2. Aloese mai le manavaina o le pefu mai lenei oloa ma aloese mai le faʻafesoʻotaʻi ma mata ma paʻu.
3. oona.Na tu'u gutu i isumu LD50:11500mg/kg.O mea mata'utia po'o le malosi pala e pei ole 2-aminonaphthalene sulfonic acid, fa'aoso fa'ato'a fa'a'a'asa ole sufuric acid ma so'a suamalie o lo'o fa'aogaina ile gaosiga.
Talosaga
Fa'alanu vavalo.E masani ona faaaoga e saunia tuusao lanumeamata lotus R, tuusao vave lanumoana FRL, tuusao vave lefulefu 2BL, apamemea masima lanumoana tuusao 2R, tuusao acid tetee lanu viole, tuusao piniki, tuusaʻo apamemea vali navy, vave lanumoana B2R, saʻo jujube GB, faapea foi e pei o le mumu mumu, moli, moli susulu X-GN, efuefu, mutia lanumeamata, mumu enaena ma isi vali.E fa'aaogaina fo'i e saunia ai le J fa'alua, vaila'au mūmū ma le phenyl J acid.
teuina ma le teuina
Faʻamatalaga Faʻapipiʻi: 25kg / taga
E tatau ona faʻamaufaʻailogaina ma puipuia mai le malamalama.Teu i totonu o se fale matutu ma mama e puipuia ai le susulu o le la ma timuga.Pe a tuʻuina, o le gutu o le pusa (paʻu) e tatau ona agai i luga e aloese ai mai le tafe o le oloa.
isi igoa: J acid; 2-amino-5-naphthol-7-sulfonic acid;6-amino-1-naphthol-3-sulfonic acid
