Kagwiritsidwe ntchito ka Auramine ndi njira yopangira:

Kapangidwe ka mankhwala Ufa wachikasu wofanana. Umasungunuka m'madzi ozizira, umasungunuka mosavuta m'madzi otentha, ndi wachikasu chowala, ndipo umawola ukawiritsa. Umakhala wachikasu ukasungunuka mu ethanol. Ufa wa utoto umakhala wopanda mtundu mu sulfuric acid yokhazikika, ndipo umasintha kukhala wachikasu wopepuka ukasungunuka; lalanje mu nitric acid yokhazikika; white precipitate mu sodium hydroxide solution.

Ntchito:

1) Chikasu chowala cha O chingagwiritsidwe ntchito popaka utoto wa silika, thonje, ulusi wa acrylic, ubweya, ndi zina zotero, komanso posindikiza mwachindunji. Mukamagwiritsa ntchito, kutentha kwa kusungunuka sikuyenera kupitirira 60°C. Chifukwa cha kusayenda bwino kwa kuwala, sichigwiritsidwa ntchito kawirikawiri mu nsalu. Chingagwiritsidwe ntchito popaka utoto wa chikopa, mapepala, utoto, ndi zina zotero.

2) Amagwiritsidwa ntchito popanga cellulose acetate, thonje lofiirira, koma lolimba pang'ono, lowala bwino, lingagwiritsidwe ntchito popanga zobiriwira kapena zofiira, ndi zina zotero. Lingagwiritsidwenso ntchito popanga utoto wa chikopa, mapepala, nsalu ndi viscose. Alkaline ingagwiritsidwe ntchito popanga utoto wa mafuta, mafuta, utoto, ndi zina zotero. Nyanja zopaka utoto zimathanso kukonzedwa kuti zigwiritsidwe ntchito mu inki.

3) Amagwiritsidwa ntchito makamaka popaka utoto wa mabakiteriya olimbana ndi asidi monga Mycobacterium tuberculosis. Pambuyo popaka utoto wa fluorescent AuramineO, mabakiteriya othamanga ndi asidi amatuluka mtundu wa lalanje wowala akawunikidwa ndi maikulosikopu ya fluorescent yokhala ndi Chemicalbook ultraviolet light source. Njirayi ingagwiritsidwe ntchito popaka utoto wa microscopy wocheperako, kuti mabakiteriya olimbana ndi asidi apezeke mwachangu.

Njira yopangira:N,N-dimethylaniline ndi formaldehyde zimakonkhetsedwa, pambuyo poyeretsedwa, kupangidwa ndi kristalo ndi kutsukidwa, zimasakanizidwa ndi sulfure, urea ndi ammonium chloride, kenako zimasefedwa ndikuumitsidwa kuti zipeze chinthu chomalizidwa. Kugwiritsa ntchito zinthu zopangira (kg/t Chemicalbook) N,N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfure (99%) 350 ammonium chloride 630 p-aminobenzene sulfonic acid (100%) 8 mchere woyengedwa 7500.

Njira1: Njira yoyeretsera imagwiritsa ntchito N,N-dimethylaniline ngati chinthu chachikulu chopangira. Choyamba, imaphatikizidwa ndi formaldehyde kuti ipange diarylmethane. Pambuyo poyeretsedwa, kusungunuka ndi kutsukidwa, imaphatikizidwa ndi urea, sulfure, ndi ammonium chloride, kenako imasefedwa. Chomaliza chimapezeka mutauma. . Kuchita kwa amination kwenikweni ndi njira ya magawo atatu ya vulcanization, imitation ndi mapangidwe a mchere mu sitepe imodzi, ndiko kuti, 4,4′-dimethylaminodiphenylmethane, sulfure, urea ndi ammonium chloride zimawonjezedwa mu ketulo ya amination molingana, ndipo kutentha kumawonjezeka kufika (200 ±5)℃, kuchitapo kanthu kwa maola 4, ndikuchotsa mu Chemicalbook. Njira 2: Njira yosungunulira Njira yatsopano yosungunulira imagwiritsa ntchito ethylene glycol ngati chosungunulira kuti ichepetse kutentha kwa reaction ndikuwonjezera kwambiri zokolola. Njira yochitira izi ndi iyi: Ikani 300g ya ethylene glycol ndi 58g ya sulfure mu ketulo yochitira izi, ndikulowetsa mpweya wa ammonia pa (140±5)℃, onjezerani 80g ya ammonium chloride patatha maola 4 mutachita izi, pitirizani kuchita izi kwa mpweya wa ammonia kwa maola 16, ndipo mpweya wonse wa ammonia ndi pafupifupi 102g. Pambuyo poti izi zachitika, kuziziritsa, kupanga makristalo, kusefa, ndi kuumitsa, mankhwalawa ndi pafupifupi 155g.
