Yayisetyenziselwa ukwenziwa kwi-β-naphthylamine.Ngenxa ye-carcinogenicity enamandla ye-β-naphthylamine, le ndlela yokuvelisa ikhutshwe, kwaye ngoku i-2-naphthylamine-1-sulfonic acid isetyenziswe njengento eluhlaza ukuvelisa i-asidi ye-J.Emva kwe-sulfonation kunye ne-hydrolysis, i-2-naphthalic acid-5-dimethyl 7-disulfonate ityuwa ye-monosodium (i-amino J acid) yafunyanwa, eyathi ingathathi hlangothi, ixutywe nge-alkali kunye ne-acidified.I-asidi ye-J yafunyanwa nge-sulfonation kunye ne-fuming sulfuric acid, i-hydrolysis, i-absorption, i-washing, isisombululo se-alkali kunye ne-asidi yokuhlamba.Ityuwa yesodium inyibilika emanzini kwaye ibonisa i-blue fluorescence.Ifudunyezwa kunye nesisombululo se-ferric trichloride ukwenza imvula emdaka-mnyama.
Ipropati yeKhemikhali
1. I-asidi ye-J idibene nesisombululo se-ferric chloride ukwenza i-precipitate emnyama emnyama;icalcium chloride ukwenza imvula etyheli emdaka;ityuwa yesodium esisiseko inyibilikiswa emanzini ibonise i-fluorescence eluhlaza okwesibhakabhaka.
2. Kuphephe ukuphefumla uthuli kule mveliso kwaye ugweme ukudibana kwamehlo nolusu.
3. inetyhefu.Iimpuku zanikwa ngomlomo i-LD50: 11500mg/kg.Izinto ezinobuthi ezinobuthi okanye ezonakalisayo kakhulu ezifana ne-2-aminonaphthalene sulfonic acid, i-fuming concentrated sulfuric acid kunye ne-caustic soda zisetyenziswa kwimveliso.
Usetyenziso
Idayi ephakathi.Isetyenziswa ikakhulu ukulungiselela ngqo lotus eluhlaza R, ngqo fast blue FRL, uthuthu ngokukhawuleza 2BL, ngqo copper ityuwa blue 2R, acid ngqo ukumelana purple, pink ngqo, idayi yobhedu ngqo navy, blue B2R fast, jujube GB ngqo, ngokunjalo. njenge-reactive scarlet, i-orenji, i-orange eqaqambileyo ye-X-GN, i-grey, ingca eluhlaza, i-brown ebomvu kunye nezinye iidayi.Ikwasetyenziselwa ukulungisa i-asidi ye-J ephindwe kabini, i-acid ebomvu kunye ne-phenyl J acid.
yokugcina kunye nokupakisha
Ukupakisha iinkcukacha: 25kg / ibhegi
Kufuneka itywinwe kwaye ikhuselwe ekukhanyeni.Gcina kwindlu eyomileyo necocekileyo ukunqanda ukuba sesichengeni selanga nemvula.Xa ibekwe, umlomo webhokisi (idrum) kufuneka ube phezulu ukuthintela ukuvuza kwemveliso.
