DSD asidhi (4,4 diaminostilbene mono-2,2 bisulfonic acid) yakakosha dhayi yepakati, inonyanya kushandiswa kugadzira fluorescent inopenya, yakananga yakaomeswa yero G, yakananga yero R, sunlight-resistant orenji F3G uye anti-moth-eating agents. COD ndeye 6000-8000mg/L, salinity iri 6% -8%, uye ruvara rune 50,000 nguva; zvikamu zvikuru zvemvura yetsvina zvinonhuhwirira organic komisheni ine nitro, amino uye sulfonic mapoka, uye reshiyo yeBOD kune COD ingori 0.03, iyo yakaoma zvakanyanya kuomesa biodegrade.
Hunhu hwemvura uye huwandu hwemvura hweDSD acid inogadzirwa mvura yetsvina yakagadzikana, asi iyo chromaticity uye sulfate concentration yakakwira zvakanyanya, zvinovaka muviri zvakaita seN uye P zviri kushomeka, uye mvura yetsvina ine chepfu uye inokuvadza, hapana muenzaniso wakabudirira wekurapa mukati. China. dsd asidhi yakapfava yero paste kana hupfu, inonyungudika mu ethanol uye ether, isinganyungudika mumvura, inonyungudika mualkali solution. (2) Inonyorerwa nyore nyore kuita tsvuku, uye ine zvimiro zveanonhuwirira acids nemaamine panguva imwe chete.
3) Chigadzirwa chemhando uye tekinoroji index: yakazara amino kukosha (maererano nehuwandu hwehuwandu hwenamira) ≥48%; yakaoma chigadzirwa zvachose amino kukosha (maererano nehuwandu hwehuwandu hwekuomeswa sampuli) ≥95.0%; alkali insoluble matter content (nehuwandu hwepaste) ≤0.05%; alkali insoluble matter content (nehuwandu hwehupfu) ≤0.08%; benzyl nyaya (nehuwandu hwemasamples) ≤0.25% yekugadzira 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. 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. Yakananga nechando yero G uye yakananga yero R, uye inoshandiswa semushonga wezvipembenene.
Organic compound chidimbu. Zita rakazara 4,4`-diaminostilbene-disulfonic acid. Inogona kushandiswa kugadzira fluorescent whitening agent uye mamwe madhayi. CAS nhamba: 81-11-8 Molecular Formula:C14H14N2O6S2 Molecular Weight：370.4008 Quality Index (Specification) Chitarisiko (Chitarisiko): light yellow poda/light yellow paste Content (Kuchena): ≥95. 0 Packing (Package): 25 mg/kg.
0 Packing (Package): 25kg / 40kg / bhegi Physical Properties Molecular Weight: 370.4, yero kana chiedza yellow crystal ine hygroscopicity. Zviri nyore kuita oxidize mumhepo. Ichi chigadzirwa chine chepfu uye chinogumbura ganda, dzivisa kusangana kwakananga nemuviri wemunhu.
Synthesis nzira: Yazvino nzira yekubatanidza ndeye p-nitrotoluene sulfonated ine fuming sulfuric acid, yobva yanaya nemvura, uye iyo yakaparadzaniswa yeNTS inoiswa oxidized pasi pe alkaline mamiriro nemhepo, uye iyo DNS mune oxidation mhinduro inodururwa nemunyu, yozoderedzwa nesimbi. upfu, uye wobva wanaya ne sulfuric acid. Upfu hwakaomeswa uye hwakaomeswa. Hupfu hunotengeswa sechinhu chakanyorova chekutengesa mudzimba, asi chinongotengeswa mumhando yehupfu kutengeserana nedzimwe nyika.
Kambani yeMit-ivy indasitiri inonyanya kugadzira DSD ACID ine huwandu hwegore hwekugadzira hwematani chiuru, uye ine chikamu chemusika chakazara che97%.
