I-DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) iyi-dye intermediate ebalulekile, esetshenziswa kakhulu ukukhiqiza izibani ezikhanyisa ukukhanya, i-G ephuzi eqandisiwe ngqo, i-R ephuzi eqondile, i-F3G e-orange engangeni elangeni kanye nama-anti-moth-eating agents. I-COD ingu-6000-8000mg/L, usawoti ungu-6%-8%, futhi umbala uphindwe izikhathi ezingu-50,000; izingxenye eziyinhloko zamanzi angcolile yizinhlanganisela ze-organic ezinuka kamnandi ezinamaqembu e-nitro, ama-amino kanye ne-sulfonic, kanti isilinganiso se-BOD ne-COD singu-0.03 kuphela, okunzima kakhulu ukubola.

Ikhwalithi yamanzi kanye nenani lamanzi lamanzi amdaka akhiqizwa yi-DSD acid kuzinzile, kodwa ukuhlushwa kwe-chromaticity kanye ne-sulfate kuphezulu kakhulu, izakhamzimba ezifana ne-N ne-P azikho, futhi amanzi amdaka aqukethe izinto ezinobuthi neziyingozi, asikho isibonelo sokwelashwa esiphumelelayo eShayina. I-dsd acid iyi-paste noma i-powder ephuzi elikhanyayo, encibilikayo ku-ethanol kanye ne-ether, engancibiliki emanzini, encibilikayo kusisombululo se-alkali. (2) I-oxidized kalula ibe bomvu, futhi inezakhiwo ze-aromatic acids nama-amine ngesikhathi esisodwa.

3) Ikhwalithi yomkhiqizo kanye nenkomba yobuchwepheshe: inani eliphelele lama-amino (ngokusho kwenani eliphelele lokunamathisela) ≥48%; inani eliphelele lama-amino lomkhiqizo owomile (ngokusho kwenani eliphelele lamasampula okomisa) ≥95.0%; okuqukethwe kwezinto ezinganyibiliki ze-alkali (ngokusho kwenani eliphelele lokunamathisela) ≤0.05%; okuqukethwe kwezinto ezinganyibiliki ze-alkali (ngokusho kwenani eliphelele lempuphu) ≤0.08%; izinto ze-benzyl (ngokusho kwenani eliphelele lamasampula) ≤0.25% yokukhiqizwa kwe-ejenti yokwenza mhlophe ye-fluorescent, i ...

Isifinyezo se-organic compound. Igama eliphelele yi-4,4`-diaminostilbene-disulfonic acid. Ingasetshenziswa ekuhlanganiseni i-fluorescent whitening agent kanye nezinye izidayi. Inombolo ye-CAS： 81-11-8 Molecular Formula：C14H14N2O6S2 Isisindo se-Molecular：370.4008 Quality Index（Specification） Ukubukeka（Ukubukeka）： impuphu ephuzi ekhanyayo/i-paste ephuzi ekhanyayo Okuqukethwe（Ubumsulwa）： ≥95. 0 Ukupakisha（Iphakheji）： 25 mg/kg.

0 Ukupakisha (Iphakheji): 25kg/40kg/isikhwama Izakhiwo Zomzimba Isisindo Se-Molecular: 370.4, ikristalu ephuzi noma ephuzi ekhanyayo ene-hygroscopicity. Kulula ukuyixuba emoyeni. Lo mkhiqizo unobuthi futhi uyacasula isikhumba, gwema ukuthintana ngqo nomzimba womuntu.

Indlela yokwenza: Indlela yokwenza yamanje i-p-nitrotoluene sulfonate efakwe i-fuming sulfuric acid, bese ifakwa amanzi, bese i-NTS ehlukanisiwe ifakwa i-oxidation ngaphansi kwezimo ze-alkaline ngomoya, bese i-DNS esixazululweni se-oxidation ifakwa usawoti, bese incishiswa nge-iron powder, bese ifakwa i-sulfuric acid. I-powder iyomiswa futhi yomiswe. I-powder ithengiswa njengomkhiqizo omanzi wokuthengiswa kwasekhaya, kodwa ithengiswa kuphela ngesimo se-powder sokuhweba kwamanye amazwe.

Inkampani yemboni ye-Mit-ivy ikhiqiza kakhulu i-DSD ACID enomthamo wokukhiqiza waminyaka yonke ongamathani ayi-1,000,000, futhi inesabelo semakethe esiphelele esingu-97%.
