Auramine Fa'aoga ma metotia fa'atupu:

O mea tau vaila'au pa'u lanu samasama. E solu i le vai malulu, faigofie ona solu i le vai vevela, e samasama samasama, ma o le a pala pe a uma ona fa'apuna. E samasama pe a solu ile ethanol. O le pa'u vali e leai se lanu i totonu o le sulfuric acid concentrated, ma e liu lanu samasama pe a uma ona fa'afefiloi; moli i le acid nitric concentrated; pa'epa'e pa'epa'e ile vaifofo sodium hydroxide.

Fa'aoga:

1) O samasama lanu samasama masani O e mafai ona faʻaaogaina mo le valiina o siliki, cotton, fiber acrylic, fulufulu mamoe, ma isi, faʻapea foʻi mo le lolomiina saʻo. A faʻaaogaina, o le vevela faʻamavae e le tatau ona sili atu i le 60°C. Ona o le le lelei o le saoasaoa o le malamalama, e seasea faʻaaogaina i ie. E mafai ona faʻaaogaina mo le valiina o paʻu, pepa, vali, ma isi.

2) Faʻaaogaina mo le cellulose acetate, cotton mordant, ae maualalo le saoasaoa, lanu susulu, e mafai ona faʻaogaina e fai ai lanu meamata pe mumu, ma isi. E mafai foi ona faʻaaogaina mo le valiina o paʻu, pepa, lino ma viscose. E mafai ona fa'aoga le alkaline e valivali ai le suau'u, ga'o, vali, ma isi mea. E mafai fo'i ona saunia vaituloto lanu mo le fa'aoga i vaitusi.

3) E masani ona faʻaaogaina mo le faʻafefeteina o siama o siama faʻamaʻi e pei ole Mycobacterium tuberculosis. A uma ona pisia i le vali felanulanua'i o le AuramineO, o le a fa'aosoina mai e le siama fa'asa'osaisa se lanu moli moli pe a su'esu'eina i se microscope fa'alelei o lo'o i ai se puna moli ultraviolet Chemicalbook. O lenei metotia e mafai ona fa'aoga mo le fa'aitiitiga fa'amataiti fa'amālositino, o lea e mafai ai ona maua vave siama fa'asa'o fa'asa'o.

Gaosiga auala:N, N-dimethylaniline ma formaldehyde e condensed, pe a uma le distillation, crystallization ma le faamamaina, ammoniated i le sulfur, urea ma le ammonium chloride, ona faamama ma mago e maua ai le oloa maeʻa. Fa'aaogā mea mata'utia (kg/t Tusi vaila'au) N,N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfur (99%) 350 ammonium chloride 630 p-aminobenzene sulfonic acid (100%) 8 masima fa'amamaina 7500.

Metotia1: O le sintering metotia faʻaaogaina N, N-dimethylaniline e avea ma mea autu autu. Muamua, e fa'aputu i formaldehyde e maua ai le diarylmethane. A maeʻa le faʻamaʻiina, faʻamaʻi ma faʻamamāina, e faʻafefeteina i le urea, sulfur, ma le ammonium chloride, ona faʻamamaina lea, E maua le oloa maeʻa pe a uma ona faʻamago. . O le tali amination e moni lava o se tali e tolu-laasaga o le vulcanization, imination ma masima fausia i le laasaga e tasi, o lona uiga, 4,4′-dimethylaminodiphenylmethane, sulfur, Urea ma ammonium chloride ua faaopoopo i le ulo amination i le fua, ma o le vevela o le faateleina i le (200 ± 5) ℃, tali mo le 4h, ma ave i fafo mai Chemicalbook. Metotia 2: Solvent Method O le auala fou e faʻaaogaina ai le solvent e faʻaaogaina ai le ethylene glycol e avea ma solvent e faʻaitiitia ai le vevela o le tali ma faʻateleina le fua. O le fa'agasologa o le tali e fa'apea: Tu'u le 300g o le ethylene glycol ma le 58g o le sulfur i totonu o le ulo tali, ma pasi i le kasa ammonia i le (140±5) ℃, fa'aopoopo le 80g o le ammonium chloride pe a uma le 4 itula o le tali, fa'aauau le tali atu o le ammonia. kesi mo le 16 itula, ma o le aofaiga atoa o le kasa ammonia e tusa ma le 102g. A maeʻa le tali, faʻamafanafana, tioata, faʻamamaina, ma faʻamago, o le oloa e tusa ma le 155g.
