Waxaa loo isticmaalaa in laga sameeyo β-naphthylamine.Sababtoo ah kansarka xooggan ee β-naphthylamine, habkan wax soo saarka ayaa la tirtiray, hadda 2-naphthylamine-1-sulfonic acid ayaa loo isticmaalaa sida alaabta ceeriin si loo soo saaro J acid.Ka dib sulfonation iyo hydrolysis, 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium cusbo (amino J acid) ayaa la helay, kaas oo markaa la dhexdhexaadiyay, oo lagu daray alkali iyo acidified.J acid waxaa lagu helay sulfonation leh qiiqa sulfuric acid, hydrolysis, nuugista, dhaqida, xalalka alkali iyo dhaqidda aashitada.Milixda soodhiyamku waxay ku milantaa biyaha waxayna muujisaa iftiin buluug ah.Waxaa lagu kululeeyaa xal ferric trichloride si ay u sameeyaan roobab brown-madow.
Hantida kiimikada
1. J aashitada kulaylka leh xal ferric chloride si ay u sameeyaan roobab madow madow;kalsiyum chloride si uu u sameeyo roob jaale ah oo bunni ah;milixda saldhigga ah ee lagu milmay biyaha ayaa muujisay fluorescence buluug ah.
2. Iska ilaali in aad ka neefsato boodhka alaabtan kana fogow taabashada indhaha iyo maqaarka.
3. sun ah.Jiirka waxaa la siiyay LD50:11500mg/kg.Walxaha cayriin ee sunta ah ama si adag u daxalka leh sida 2-aminonaphthalene sulfonic acid, qiiqa sulfuric acid iyo soodhaha caustic ayaa loo isticmaalaa wax soo saarka.
Codsiyada
Dhexdhexaadiyeyaasha dheeha.Waxaa inta badan loo isticmaalaa in lagu diyaariyo lotus cagaar toos ah R, FRL buluug toos ah, dambas si toos ah 2BL, cusbo naxaas toos ah buluug 2R, si toos ah acid u adkaysta guduud, casaan toos ah, Navy dheeh naxaas toos ah, B2R buluug degdeg ah, jujube GB, iyo sidoo kale sida casaan-casaan, oranji, liimidi dhalaalaya oo dhalaalaya X-GN, cawl, cagaar caws, bunni cas iyo midabyo kale.Waxa kale oo loo isticmaalaa in lagu diyaariyo laba-jibbaaran ee acid J, guduud acid iyo phenyl J acid.
kaydinta iyo baakaynta
Faahfaahinta Baakadaha: 25kg/bac
Waa in la xidhaa lagana ilaaliyaa iftiinka.Ku kaydi guri nadiif ah oo qallalan si aad uga hortagto soo-gaadhista iftiinka qorraxda iyo roobka.Marka la dhigo, afka sanduuqa (durbaan) waa inuu kor u ahaadaa si looga fogaado daadinta alaabta.
