Isetshenziselwa ukwenziwa nge-β-naphthylamine.Ngenxa ye-carcinogenicity eqinile ye-β-naphthylamine, le ndlela yokukhiqiza isusiwe, futhi manje i-2-naphthylamine-1-sulfonic acid isetshenziswa njengento eluhlaza ukukhiqiza i-J acid.Ngemuva kwe-sulfonation kanye ne-hydrolysis, i-2-naphthalic acid-5-dimethyl 7-disulfonate monosodium usawoti (i-amino J acid) yatholakala, eyabe ingathathi hlangothi, ihlanganiswe ne-alkali ne-asidi.I-asidi ye-J yatholwa nge-sulfonation nge-fuming sulfuric acid, i-hydrolysis, ukumuncwa, ukuwasha, isixazululo se-alkali nokugeza okune-asidi.Usawoti we-sodium uncibilika emanzini futhi ubonisa i-fluorescence eluhlaza okwesibhakabhaka.Ishisiswe ngokuhlanganyela nesisombululo se-ferric trichloride ukwenza imvula ensundu-mnyama.
Impahla yamakhemikhali
1. I-asidi ye-J ishisiswe nekhambi le-ferric chloride ukwenza imvula ensundu ngokumnyama;i-calcium chloride ukwenza imvula ensundu ngokuphuzi;isisekelo sosawoti wesodium esincibilikisiwe emanzini sibonise i-fluorescence eluhlaza okwesibhakabhaka.
2. Gwema ukuhogela uthuli oluphuma kulo mkhiqizo futhi ugweme ukuthintana namehlo nesikhumba.
3. enobuthi.Amagundane anikezwa ngomlomo i-LD50: 11500mg/kg.Izinto zokusetshenziswa ezinobuthi noma ezigqwala kakhulu njenge-2-aminonaphthalene sulfonic acid, i-sulfuric concentrated concentrated sulfuric acid kanye ne-caustic soda zisetshenziswa ekukhiqizeni.
Izinhlelo zokusebenza
Udayi uphakathi.Ikakhulukazi isetshenziselwa ukulungiselela i-lotus eluhlaza eqondile R, i-FRL esheshayo eluhlaza okwesibhakabhaka, umlotha oqondile oqondile we-2BL, usawoti oqondile wethusi oluhlaza okwesibhakabhaka 2R, ukumelana ne-asidi eqondile, i-pink eqondile, idayi yethusi eqondile ye-navy, i-B2R eluhlaza okwesibhakabhaka, i-jujube GB eqondile, kanye njengombala obomvu, osawolintshi, osawolintshi okhanyayo we-X-GN, ompunga, oluhlaza okotshani, onsundu obomvu nabanye odayi.Iphinde isetshenziselwe ukulungisa i-double J acid, i-scarlet acid ne-phenyl J acid.
isitoreji nokupakisha
Ukupakisha Imininingwane: 25kg / isikhwama
Kufanele ivalwe futhi ivikelwe ekukhanyeni.Gcina endlini eyomile, ehlanzekile ukuze uvimbele ukuchayeka elangeni nasemvuleni.Uma ibekwe, umlomo webhokisi (isigubhu) kufanele ube phezulu ukuze ugweme ukuvuza komkhiqizo.
