Acid Liab 73tseem hu ua Acid Brilliant Scarlet GR. CAS tus lej: 5413-75-2 Acid Liab 73 feem ntau siv ua cov xim zas xim hauv kev lag luam textile. Nws feem ntau siv los zas xim rau cov ntaub plaub, txhob lo lo ntxhuav, thiab nylon. Nws paub txog nws cov xim ci ntsa iab thiab kav ntev, thiab feem ntau nws tau npaj ua cov tshuaj ua ntej siv rau cov ntaub los ntawm ntau yam txheej txheem zas xim.
Cov khoom siv tshuaj lom neeg: hmoov daj liab daj. Yaj hauv dej yog cov kua liab, yaj hauv cawv thiab fibrin, tsis yaj hauv acetone, tsis yaj hauv lwm cov kuab tshuaj organic. Yog tias muaj concentrated sulfuric acid, nws yog xim liab liab, thiab tsim cov xim av liab tom qab dilution; Thaum concentrated nitric acid yog xiav, nws hloov xim av txiv ntseej mus rau txiv kab ntxwv. Cov kua dej tau ntxiv nrog concentrated hydrochloric acid los tsim cov xim av liab tsaus, thiab cov kua sodium hydroxide los tsim cov xim av tsaus. Cov xim ntawm tooj liab thiab hlau ions yog tsaus thaum zas xim. Kev tso tawm zoo.
Acid liab 73 yog cov xim pleev xim, thiab nws txoj kev tsim khoom feem ntau muaj cov kauj ruam hauv qab no:
1. Kev npaj cov khoom siv raw: siv cov tshuaj aniline ua cov khoom pib, cov tshuaj amine aromatic ntawm cov xim pleev xim yog npaj los ntawm kev sib xyaw ua ke.
2. Kev sib xyaw ua ke: cov tshuaj amine uas muaj ntxhiab tsw qab sib xyaw nrog sodium nitrite nyob rau hauv cov kua qaub los tsim cov nitroso aromatic amine.
3. Kev sib txuas ua ke: cov nitroso aromatic amine yog sib txuas nrog cov binary heterocyclic compounds (xws li naphthalene, pyridine, thiab lwm yam) los tsim cov khoom sib txuas.
4. Kev tsim cov tshuaj sib xyaw ruaj khov: los ntawm kev kho cov xwm txheej ntawm cov tshuaj tiv thaiv, xws li kub, pH, thiab lwm yam, cov tshuaj tiv thaiv tuaj yeem ncav cuag qhov sib txuas zoo tagnrho thiab tsim cov khoom sib txuas ruaj khov.
5. Crystallization thiab ziab: cov kua xim tau los ntawm kev sib xyaw ua ke yog crystallized thiab ziab kom tau txais cov khoom xim liab 73 ruaj khov.
Peb lub Hoobkas tshwj xeeb hauv kev tsim khoom ntawmkua qaub liab 73,kua qaub txiv kab ntxwv II, acid kub G, Rhodamine B, Malachite Ntsuab, Auramine O Concthiab lwm yam xim, cov khoom tsim nyog rau: ntawv ~ tshuaj tsw qab ~ tais qe
