DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) yog ib qho tseem ceeb dye intermediate, feem ntau yog siv los tsim cov fluorescent brighteners, ncaj khov daj G, ncaj daj R, tshav ntuj-resistant txiv kab ntxwv F3G thiab tshuaj tiv thaiv kab tsuag. COD yog 6000-8000mg / L, salinity yog 6% -8%, thiab xim yog 50,000 zaug; Cov khoom tseem ceeb ntawm cov dej khib nyiab yog cov tshuaj tsw qab organic nrog nitro, amino thiab sulfonic pawg, thiab qhov piv ntawm BOD rau COD tsuas yog 0.03, uas yog qhov nyuaj heev rau biodegrade.
Cov dej zoo thiab cov dej kom muaj nuj nqis ntawm DSD acid cov dej khib nyiab yog qhov ruaj khov, tab sis cov chromaticity thiab sulfate concentration yog siab heev, cov as-ham xws li N thiab P tsis muaj, thiab cov dej khib nyiab muaj cov tshuaj lom thiab tsis zoo, tsis muaj kev kho zoo piv txwv hauv Tuam Tshoj. dsd acid yog lub teeb daj los yog hmoov, soluble hauv ethanol thiab ether, insoluble hauv dej, soluble hauv alkali tov. (2) Nws yooj yim oxidized rau liab, thiab muaj cov yam ntxwv ntawm aromatic acids thiab amines tib lub sijhawm.
3) Cov khoom lag luam zoo thiab cov txiaj ntsig kev lag luam: tag nrho cov txiaj ntsig amino (raws li tag nrho cov khoom muab tshuaj txhuam) ≥48%; cov khoom qhuav tag nrho cov nqi amino (raws li tag nrho cov qauv ua kom qhuav) ≥95.0%; alkali insoluble teeb meem cov ntsiab lus (los ntawm tag nrho cov muab tshuaj txhuam) ≤0.05%; alkali insoluble teeb meem cov ntsiab lus (los ntawm tag nrho cov nyiaj ntawm hmoov) ≤0.08%; benzyl teeb meem (los ntawm tag nrho cov qauv) ≤0.25% rau zus tau tej cov fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, tshuaj fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, tshuaj fluorescent whitening agent Tus neeg saib xyuas dawb, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, tshuaj fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, tshuaj fluorescent whitening agent. Direct khov daj G thiab ncaj qha daj R, thiab siv los ua tshuaj tua kab.
Organic compound abbreviation. Lub npe tag nrho yog 4,4'-diaminostilbene-disulfonic acid. Nws tuaj yeem siv rau kev sib txuas ntawm fluorescent whitening agent thiab lwm yam dyes. CAS No .: 81-11-8 Molecular Formula: C14H14N2O6S2 Molecular Luj: 370.4008 Quality Index (Specification) Pearance (Appearance): Lub teeb daj hmoov / lub teeb daj paste Cov ntsiab lus (Purity): ≥95. 0 Ntim (Package): 25 mg / kg.
0 Ntim (Package): 25kg / 40kg / hnab Physical Properties Molecular Luj: 370.4, daj lossis lub teeb daj crystal nrog hygroscopicity. Nws yooj yim rau oxidize hauv huab cua. Cov khoom no yog tshuaj lom thiab irritating ntawm daim tawv nqaij, tsis txhob sib cuag nrog tib neeg lub cev.
Txoj kev sib txuas: Txoj kev sib txuas tam sim no yog p-nitrotoluene sulfonated nrog fuming sulfuric acid, tom qab ntawd precipitated nrog dej, thiab NTS sib cais yog oxidized nyob rau hauv alkaline tej yam kev mob nrog huab cua, thiab DNS nyob rau hauv oxidation tov yog precipitated nrog ntsev, ces txo nrog hlau. hmoov, thiab ces precipitated nrog sulfuric acid. Cov hmoov yog qhuav thiab qhuav. Cov hmoov yog muag raws li cov khoom ntub dej rau kev muag khoom hauv tsev, tab sis tsuas yog muag hauv cov hmoov hmoov rau kev lag luam thoob ntiaj teb.
Lub tuam txhab kev lag luam Mit-ivy feem ntau tsim DSD ACID nrog lub peev xwm tsim khoom txhua xyoo ntawm 1,000,000 tons, thiab muaj kev lag luam tag nrho ntawm 97%.
