Auramine Kushandisa uye synthesis nzira:

Chemical properties Yellow uniform powder. Inonyungudika mumvura inotonhora, inonyungudika nyore mumvura inopisa, inopenya yero, uye inoora mushure mekuvira. Iyero kana yanyungudika mu ethanol. Iyo dhayi poda haina ruvara mune yakasanganiswa sulfuric acid, uye inoshanduka yero yero mushure mekunatswa; orange mu concentrated nitric acid; white precipitate mu sodium hydroxide solution.

Zvishandiso:

1)Basic inopenya yero O inogona kushandiswa kudhaya sirika, donje, acrylic fiber, makushe, nezvimwewo, uye zvakare kudhinda zvakananga. Paunenge uchishandisa, tembiricha yekunyungudutsa haifanire kudarika 60 ° C. Nekuda kwekusamhanya kwechiedza, haiwanzo kushandiswa mumicheka. Inogona kushandiswa kugadzira ganda, pepa, pendi, nezvimwe.

2) Inoshandiswa kune cellulose acetate, mordant cotton, asi yakaderera kukurumidza, ruvara rwakajeka, inogona kushandiswa kugadzira girini kana tsvuku, etc. Inogonawo kushandiswa kudhaya dehwe, pepa, rineni uye viscose. Alkaline inogona kushandiswa kupendesa mafuta, mafuta, pendi, nezvimwewo. Madhamu emavara anogonawo kugadzirirwa kushandiswa mumainki.

3) Inonyanya kushandiswa kusvibisa fluorescent yeacid-resistant mabhakitiriya akadai seMycobacterium tuberculosis. Mushure mekusvibiswa nedhayi yefluorescent AuramineO, bhakitiriya inokurumidza acid inoburitsa ruvara rweorenji rwakajeka kana ichiongororwa nemicroscope yefluorescent ine Chemicalbook ultraviolet light source. Iyi nzira inogona kushandiswa kudzikisa magnification microscopy, saka mabhakitiriya anodzivirira acid anogona kuwanikwa nekukurumidza.

Nzira yekugadzira:N, N-dimethylaniline uye formaldehyde zvakanyungudutswa, mushure mekuita distillation, crystallization uye kucheneswa, ammoniated ne sulfur, urea uye ammonium chloride, zvino inosefa uye yakaomeswa kuti iwane chigadzirwa chakapedzwa. Raw material kushandiswa (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 wakacheneswa munyu 7500.

Nzira1: Iyo sintering nzira inoshandisa N,N-dimethylaniline seyakanyanya mbishi zvinhu. Kutanga, iyo yakanyungudutswa ne formaldehyde kuwana diarylmethane. Mushure mekuita distillation, crystallization uye kucheneswa, inonatswa neurea, sulfur, uye ammonium chloride, uye yozopepetwa, Chigadzirwa chakapedzwa chinowanikwa mushure mekuoma. . Iyo amination reaction ndeye nhanho-nhatu yekuita kwevulcanization, kumimina uye kuumbwa kwemunyu mune imwe nhanho, kureva, 4,4'-dimethylaminodiphenylmethane, sulfur, urea uye ammonium chloride inowedzerwa kune kettle yekumisikidza muchikamu, uye tembiricha iri. yakawedzera kusvika (200 ±5) ℃, ita kwe4h, uye ibudise muChemicalbook. Method 2: Solvent nzira Iyo ichangobva kugadzirwa solution nzira inoshandisa ethylene glycol sechinhu chinonyungudutsa kuderedza kuita tembiricha uye kuwedzera zvakanyanya goho. Maitiro ekuita ndeaya anotevera: Isa 300g ye ethylene glycol uye 58g yesarufa mu kettle inopindura, uye pfuura muammonia gasi pa (140±5) ℃, wedzera 80g yeammonium chloride mushure memaawa mana ekuita, enderera nekuita kweammonia. gasi kwemaawa gumi nematanhatu, uye huwandu hwese hweammonia gasi hunosvika 102g. Mushure mekuita kwapera, kutonhora, crystallization, kusefa, uye kuomesa, chigadzirwa chinenge 155g.
