Auramine Siv thiab kev sib xyaw ua ke:

Cov khoom siv tshuaj Yellow uniform hmoov. Nws yog soluble hauv dej txias, yooj yim soluble hauv dej kub, nws yog xim daj, thiab nws yuav decompose tom qab boiling. Nws yog daj thaum soluble hauv ethanol. Cov hmoov zas xim tsis muaj xim nyob rau hauv cov concentrated sulfuric acid, thiab hloov lub teeb daj tom qab dilution; txiv kab ntxwv nyob rau hauv concentrated nitric acid; dawb precipitate nyob rau hauv sodium hydroxide tov.

Kev siv:

1) Cov xim daj daj O tuaj yeem siv rau dyeing txhob lo lo ntxhuav, paj rwb, acrylic fiber, ntaub plaub, thiab lwm yam., thiab kuj rau luam ntawv ncaj qha. Thaum siv, qhov kub dissolving yuav tsum tsis pub tshaj 60 ° C. Vim nws qhov tsis zoo ntawm lub teeb nrawm, nws tsis tshua muaj siv hauv textiles. Nws tuaj yeem siv rau xim tawv, ntawv, xim, thiab lwm yam.

2) Siv rau cellulose acetate, mordant paj rwb, tab sis tsis tshua muaj ceev, ci xim, yuav siv tau los ua ntsuab los yog liab, thiab lwm yam. Nws kuj siv tau rau dyeing tawv, ntawv, linen thiab viscose. Alkaline tuaj yeem siv rau xim roj, roj, pleev xim, thiab lwm yam. Xim pas dej kuj tuaj yeem npaj siv rau hauv inks.

3) Feem ntau yog siv rau fluorescent staining ntawm cov kab mob acid-resistant xws li Mycobacterium tuberculosis. Tom qab staining nrog cov fluorescent dye AuramineO, cov kab mob acid-ceev yuav emit ib tug ci txiv kab ntxwv xim thaum soj ntsuam nrog ib tug fluorescent microscope uas muaj ib tug Chemicalbook ultraviolet lub teeb qhov chaw. Txoj kev no tuaj yeem siv rau kev siv lub microscopy qis dua, yog li cov kab mob acid-resistant tuaj yeem pom sai dua.

Txoj kev tsim khoom:N, N-dimethylaniline thiab formaldehyde yog condensed, tom qab distillation, crystallization thiab purification, ammoniated nrog sulfur, urea thiab ammonium chloride, ces lim thiab qhuav kom tau cov khoom tiav. Raw khoom noj (kg/t Chemicalbook) N, N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfur (99%) 350 ammonium chloride 630 p-aminobenzene sulfonic acid (100%) 8 refined ntsev 7500.

Txoj kev1: Txoj kev sintering siv N, N-dimethylaniline ua cov khoom siv tseem ceeb. Ua ntej, nws yog condensed nrog formaldehyde kom tau diarylmethane. Tom qab distillation, crystallization thiab purification, nws yog ammoniated nrog urea, sulfur, thiab ammonium chloride, thiab ces lim, cov khoom tiav yog tau tom qab ziab. . Cov tshuaj tiv thaiv amination yog peb-kauj ruam ntawm vulcanization, immination thiab ntsev tsim nyob rau hauv ib kauj ruam, uas yog, 4,4'-dimethylaminodiphenylmethane, sulfur, urea thiab ammonium chloride yog ntxiv rau amination kettle nyob rau hauv feem, thiab qhov kub thiab txias yog nce mus rau (200 ± 5) ℃, hnov ​​​​mob rau 4h, thiab tshem tawm ntawm Chemicalbook. Txoj Kev 2: Cov txheej txheem hnyav Cov txheej txheem tshiab tsim cov kuab tshuaj siv ethylene glycol ua cov kuab tshuaj kom txo tau cov tshuaj tiv thaiv kub thiab ua kom cov qoob loo ntau ntxiv. Cov txheej txheem tshuaj tiv thaiv yog raws li hauv qab no: Muab 300g ntawm ethylene glycol thiab 58g sulfur rau hauv cov tshuaj tiv thaiv kettle, thiab dhau hauv ammonia roj ntawm (140 ± 5) ℃, ntxiv 80g ntawm ammonium chloride tom qab 4 teev cov tshuaj tiv thaiv, txuas ntxiv cov tshuaj tiv thaiv ammonia. roj rau 16 teev, thiab tag nrho cov roj ammonia yog li 102g. Tom qab cov tshuaj tiv thaiv tiav, txias, crystallization, lim, thiab ziab, cov khoom yog hais txog 155g.
