I-asidi ye-DSD (4,4 diaminostilbene mono-2,2 bisulfonic acid) sisixhobo esibalulekileyo sombala, esisetyenziselwa kakhulu ukuvelisa izikhanyisi ze-fluorescent, i-G etyheli eqandisiweyo ngqo, i-R etyheli ngqo, i-F3G yeorenji engangenisi ilanga kunye nee-anti-moth-eating agents. I-COD yi-6000-8000mg/L, ityuwa yi-6%-8%, kwaye umbala uphindwe ka-50,000; izinto eziphambili zamanzi amdaka zii-compounds ze-organic ezine-nitro, i-amino kunye ne-sulfonic groups, kwaye umlinganiselo we-BOD kwi-COD yi-0.03 kuphela, okunzima kakhulu ukubola.

Umgangatho wamanzi kunye nobungakanani bamanzi e-DSD acid production water amdaka azinzile, kodwa i-chromaticity kunye ne-sulfate concentration ziphezulu kakhulu, izondlo ezifana ne-N kunye ne-P azikho, kwaye amanzi amdaka aqulethe izinto ezinobuthi nezinobungozi, akukho mzekelo wonyango ophumeleleyo eTshayina. I-dsd acid yintlama etyheli ekhanyayo okanye umgubo, enyibilikayo kwi-ethanol kunye ne-ether, ayinyibiliki emanzini, inyibilika kwisisombululo se-alkali. (2) Inyibilikiswa lula ibe bomvu, kwaye ineempawu ze-aromatic acids kunye ne-amines ngaxeshanye.

3) Umgangatho wemveliso kunye nesalathisi sobuchwephesha: ixabiso lilonke le-amino (ngokwenani lilonke le-paste) ≥48%; ixabiso lilonke lemveliso eyomileyo le-amino (ngokwenani lilonke leesampuli zokomisa) ≥95.0%; umxholo we-alkali onganyibilikiyo (ngokwenani lilonke le-paste) ≤0.05%; umxholo we-alkali onganyibilikiyo (ngokwenani lilonke le-powder) ≤0.08%; i-benzyl matter (ngokwenani lilonke leesampuli) ≤0.25% yokuvelisa i-agent yokumhlophe ye-fluorescent, ...

Isifinyezo se-organic compound. Igama elipheleleyo yi-4,4`-diaminostilbene-disulfonic acid. Ingasetyenziselwa ukwenziwa kwe-fluorescent whitening agent kunye nezinye iidayi. Inombolo ye-CAS: 81-11-8 Ifomula yeMolekyuli：C14H14N2O6S2 Ubunzima beMolekyuli：370.4008 Isalathiso soMgangatho（Inkcazo） Inkangeleko（Inkangeleko）： umgubo otyheli okhanyayo/intlama etyheli ekhanyayo Umxholo（Ubumsulwa）： ≥95. 0 Ukupakisha（Iphakheji）： 25 mg/kg.

0 Ukupakisha (Iphakheji): 25kg/40kg/ingxowa Iipropati Zomzimba Ubunzima beMolekyuli: 370.4, ikristale etyheli okanye ekhanyayo etyheli ene-hygroscopicity. Kulula ukuyikhupha emoyeni. Le mveliso inetyhefu kwaye iyacaphukisa ulusu, kuphephe ukudibana ngqo nomzimba womntu.

Indlela yokwenziwa: Indlela yokwenziwa ngoku yi-p-nitrotoluene sulfonate ene-fuming sulfuric acid, emva koko ivuthelwe ngamanzi, kwaye i-NTS eyahlukileyo ivuthelwe phantsi kweemeko ze-alkaline ngomoya, kwaye i-DNS kwisisombululo se-oxidation ivuthelwe ngetyuwa, emva koko ivuthelwe nge-iron powder, emva koko ivuthelwe nge-sulfuric acid. Umgubo uyomiswa kwaye womiswe. Umgubo uthengiswa njengemveliso emanzi yokuthengisa ekhaya, kodwa uthengiswa kuphela ngohlobo lwe-powder kurhwebo lwamazwe ngamazwe.

Inkampani yeshishini leMit-ivy ivelisa ikakhulu iDSD ACID enomthamo wokuvelisa we-1,000,000 yeetoni ngonyaka, kwaye inesabelo semarike esipheleleyo se-97%.
