Acid Liab 73Kuj hu ua Acid Brilliant Scarlet GR.CAS Number: 5413-75-2 Acid Liab 73 feem ntau yog siv los ua cov kua qaub hauv kev lag luam textile.Nws feem ntau yog siv los dye wool, silk, thiab nylon fabrics.Nws yog lub npe hu rau nws cov xim vibrant thiab kav ntev, thiab nws yog feem ntau npaj raws li kev daws teeb meem ua ntej siv rau cov ntaub los ntawm ntau yam kev dyeing.
Chemical zog daj lub teeb liab hmoov.Soluble hauv dej yog cov tshuaj liab, soluble hauv cawv thiab fibrin, insoluble hauv acetone, insoluble hauv lwm cov kuab tshuaj organic.Nyob rau hauv cov ntaub ntawv ntawm concentrated sulfuric acid, nws yog liab doog ntshav, thiab ua reddish xim av precipitate tom qab dilution;Thaum concentrated nitric acid yog xiav, nws hloov cov txiv ntseej xim av rau txiv kab ntxwv.Cov tshuaj aqueous tau ntxiv nrog cov concentrated hydrochloric acid los tsim cov xim liab xim av precipitate, thiab cov kua sodium hydroxide los tsim cov xim av tsaus nti.Cov xim ntawm tooj liab thiab hlau ions yog tsaus ntuj thaum dyeing.Kev tshem tawm yog qhov zoo.
Acid liab 73 yog cov xim hluavtaws, thiab nws txoj kev tsim khoom feem ntau muaj cov kauj ruam hauv qab no:
1.Raw khoom npaj: siv aniline tebchaw raws li cov khoom pib, aromatic amine derivatives ntawm dyes yog npaj los ntawm hluavtaws cov tshuaj tiv thaiv.
2.Compound synthesis: aromatic amine derivatives react nrog sodium nitrite nyob rau hauv acidic tej yam kev mob los tsim nitroso aromatic amine.
3.Coupling cov tshuaj tiv thaiv: cov nitroso aromatic amine yog ua ke nrog binary heterocyclic compounds (xws li naphthalene, pyridine, thiab lwm yam) los tsim cov khoom sib txuas.
4.Synthesis ntawm cov tebchaw ruaj khov: los ntawm kev kho cov tshuaj tiv thaiv, xws li kub, pH, thiab lwm yam., cov tshuaj tiv thaiv tuaj yeem ncav cuag qhov zoo tshaj plaws coupling degree thiab tsim cov khoom sib txuas ruaj khov.
5.Crystallization thiab ziab: cov dye tov tau los ntawm synthesis yog crystallized thiab qhuav kom tau ib tug ruaj khov acid liab 73 dye khoom.
Peb lub Hoobkas tshwj xeeb hauv kev tsim khoomqaub 73,acid txiv kab ntxwv II, acid golden G, Rhodamine B, Malachite Ntsuab, Auramine O Concthiab lwm yam dyes, cov khoom tsim nyog rau: ntawv ~ xyab ~ qe tais
