Kugwiritsa ntchito Auramine ndi kaphatikizidwe:

Mankhwala katundu Yellow yunifolomu ufa. Imasungunuka m'madzi ozizira, imasungunuka mosavuta m'madzi otentha, ndi yachikasu chowala, ndipo imawola ikapsa. Ndi chikasu pamene sungunuka Mowa. Ufa wa utoto umakhala wopanda utoto mu sulfuric acid wokhazikika, ndipo umasintha kukhala wachikasu pambuyo pakuchepetsedwa; lalanje mu anaikira nitric asidi; white precipitate mu sodium hydroxide solution.

Zogwiritsa:

1) Basic wonyezimira wachikasu O angagwiritsidwe ntchito popaka silika, thonje, ulusi wa acrylic, ubweya, etc., komanso kusindikiza mwachindunji. Mukamagwiritsa ntchito, kutentha sikuyenera kupitirira 60 ° C. Chifukwa cha kusathamanga kwake kopepuka, sikumagwiritsidwa ntchito kawirikawiri mu nsalu. Itha kugwiritsidwa ntchito pokongoletsa zikopa, pepala, utoto, ndi zina.

2) Amagwiritsidwa ntchito pa cellulose acetate, mordant thonje, koma kutsika pang'ono, mtundu wowala, ukhoza kugwiritsidwa ntchito popanga zobiriwira kapena zofiira, ndi zina zotero. Zamchere zitha kugwiritsidwa ntchito kupaka mafuta, mafuta, utoto, ndi zina. Nyanja zamitundu zimathanso kukonzedwa kuti zigwiritsidwe ntchito mu inki.

3) Makamaka ntchito fulorosenti kudetsa mabakiteriya asidi zosagwira monga Mycobacterium chifuwa chachikulu. Pambuyo podetsedwa ndi utoto wa fulorosenti AuramineO, mabakiteriya othamanga kwambiri a asidi amatulutsa mtundu wonyezimira wa lalanje akayang'aniridwa ndi microscope ya fulorosenti yomwe ili ndi gwero la kuwala kwa Chemicalbook ultraviolet. Njirayi ingagwiritsidwe ntchito pochepetsa ma microscopy, kotero kuti mabakiteriya osamva asidi amatha kupezeka mwachangu.

Njira yopangira:N, N-dimethylaniline ndi formaldehyde amafupikitsidwa, pambuyo pa distillation, crystallization ndi kuyeretsedwa, ammoniated ndi sulfure, urea ndi ammonium chloride, kenako amasefedwa ndikuwumitsa kuti apeze mankhwala omalizidwa. Kugwiritsa ntchito zopangira (kg/t Chemicalbook) N,N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfure (99%) 350 ammonium kolorayidi 630 p-aminobenzene sulfonic acid (100%) 8 mchere woyenga 7500.

Njira1: Njira yopangira sintering imagwiritsa ntchito N,N-dimethylaniline ngati zopangira zazikulu. Choyamba, imapangidwa ndi formaldehyde kuti ipeze diarylmethane. Pambuyo distillation, crystallization ndi kuyeretsedwa, ndi ammoniated ndi urea, sulfure, ndi ammonium kolorayidi, ndiyeno amasefedwa, Chomalizidwa analandira pambuyo kuyanika. . The amination reaction kwenikweni ndi njira zitatu za vulcanization, imination ndi mapangidwe amchere mu sitepe imodzi, ndiko kuti, 4,4'-dimethylaminodiphenylmethane, sulfure, urea ndi ammonium chloride amawonjezedwa ku ketulo ya amination molingana, ndipo kutentha kumakhala. kuchuluka mpaka (200 ±5) ℃, kuchita kwa 4h, ndikutuluka mu Chemicalbook. Njira 2: Njira yosungunulira Njira yosungunulira yomwe yangopangidwa kumene imagwiritsa ntchito ethylene glycol ngati zosungunulira kuti muchepetse kutentha komwe kumayendera ndikuwonjezera zokolola. The ndondomeko anachita motere: Ikani 300g wa ethylene glycol ndi 58g wa sulfure mu ketulo anachita, ndi kudutsa ammonia mpweya pa (140 ± 5) ℃, kuwonjezera 80g wa ammonium kolorayidi pambuyo 4 hours anachita, kupitiriza zimene ammonia anachita. mpweya kwa maola 16, ndipo kuchuluka kwa mpweya wa ammonia ndi pafupifupi 102g. Zomwezo zikatha, kuzizira, crystallization, kusefa, ndi kuyanika, mankhwalawa ndi pafupifupi 155g.
