Aishandiswa kugadzirwa kubva β-naphthylamine.Nekuda kweiyo carcinogenicity yakasimba ye β-naphthylamine, iyi nzira yekugadzira yakabviswa, uye ikozvino 2-naphthylamine-1-sulfonic acid inoshandiswa seyakasvibirira kugadzira J acid.Mushure me sulfonation uye hydrolysis, 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium munyu (amino J acid) yakawanikwa, iyo yakazogadziriswa, yakasanganiswa nealkali uye acidified.J asidhi yakawanikwa ne sulfonation ine fuming sulfuric acid, hydrolysis, absorption, washing, alkali solution uye acidizing washing.Iyo sodium munyu inonyungudika mumvura uye inoratidza bhuruu fluorescence.Inodziya pamwe chete neferric trichloride mhinduro kuti igadzire kunaya kwebrown-dema.
Chemical property
1. J asidhi yakabatanidzwa neferric chloride solution kuti igadzire mvura yakasviba yakasviba;calcium chloride kuita yellowish brown precipitate;base sodium munyu yakanyungudika mumvura yairatidza blue fluorescence.
2. Dzivisa kufema guruva kubva pachigadzirwa ichi uye usasangana nemeso uye ganda.
3. chepfu.Makonzo akapiwa nemuromo LD50:11500mg/kg.Muchetura kana corrosive mbishi zvinhu zvakaita se2-aminonaphthalene sulfonic acid, fuming concentrated sulfuric acid uye caustic soda zvinoshandiswa mukugadzira.
Applications
Dhayi pakati.Inonyanya kushandiswa kugadzirira yakananga girini lotus R, yakananga inokurumidza bhuruu FRL, yakananga inokurumidza madota 2BL, yakananga mhangura yemunyu yebhuruu 2R, yakananga acid inodzivirira yepepuru, yakananga pink, yakananga mhangura dhayi navy, inokurumidza bhuruu B2R, yakananga jujube GB, zvakare. se reactive dzvuku, orenji, brilliant orenji X-GN, grey, uswa hwakasvibirira, tsvuku tsvuku uye mamwe madhayi.Inoshandiswawo kugadzira kaviri J asidhi, tsvuku asidhi uye phenyl J asidhi.
kuchengetedza uye kurongedza
Packaging Details: 25kg / bhegi
Inofanira kuvharwa uye kudzivirirwa kubva kuchiedza.Chengetedza muimba yakaoma, yakachena kudzivirira kusangana nechiedza chezuva nemvura.Kana yaiswa, muromo webhokisi (dhiramu) unofanirwa kukwira kumusoro kudzivirira kubuda kwechigadzirwa.
