I-asidi ye-DSD (4,4 diaminostilbene mono-2,2 bisulfonic acid) yidayi ebalulekileyo ephakathi, isetyenziselwa ukuvelisa izikhanyisi ze-fluorescent, i-gland enomkhenkce ethe ngqo, i-R ngqo, i-Rheli ethe ngqo, i-F3G enganyangekiyo ekukhanyeni kwelanga kunye ne-anti-moth-eating agents. I-COD yi-6000-8000mg / L, ityuwa yi-6% -8%, kunye nombala ngamaxesha angama-50,000; ezona nxalenye ziphambili zamanzi amdaka zizikhompawundi ezinevumba elimnandi ne-nitro, i-amino kunye namaqela e-sulfonic, kwaye umlinganiselo we-BOD ukuya kwi-COD yi-0.03 kuphela, ekunzima kakhulu ukuyihlaziya.
Umgangatho wamanzi kunye nobungakanani bamanzi emveliso ye-asidi ye-DSD yamanzi amdaka azinzile, kodwa i-chromaticity kunye ne-sulfate concentration iphezulu kakhulu, izondlo ezifana ne-N kunye ne-P azikho, kwaye amanzi amdaka aqulethe izinto ezinobuthi neziyingozi, akukho mzekelo wonyango oluphumelelayo eTshayina. I-dsd acid yintlama etyheli ekhanyayo okanye umgubo, onyibilikayo kwi-ethanol kunye ne-ether, enganyibiliki emanzini, enyibilika kwisisombululo sealkali. (2) I-oxidized ngokulula ibe bomvu, kwaye ineempawu ze-aromatics kunye ne-amines ngexesha elifanayo.
3) Umgangatho wemveliso kunye nesalathisi sobugcisa: ixabiso elipheleleyo le-amino (ngokwexabiso elipheleleyo lokunamathisela) ≥48%; imveliso eyomileyo ixabiso lilonke le-amino (ngokwexabiso elipheleleyo leesampuli zokumisa) ≥95.0%; umxholo we-alkali onganyibilikiyo (ngexabiso lilonke lokuncamathisela) ≤0.05%; umxholo we-alkali onganyibilikiyo (ngexabiso lilonke lomgubo) ≤0.08%; i-benzyl umba (ngesixa sisonke seesampulu) ≤0.25% yokwenziwa kwe-arhente emhlophe ye-fluorescent, i-agent emhlophe ye-fluorescent, i-agent emhlophe ye-fluorescent, i-agent emhlophe ye-fluorescent, i-agent emhlophe ye-fluorescent, i-agent emhlophe e-fluorescent, i-agent emhlophe e-fluorescent, i-fluorescent whitening agent i-arhente emhlophe, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-agent emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe e-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent. Umthubi othe ngqo we-G kunye no-R otyheli othe ngqo, kwaye usetyenziswa njengesibulali zinambuzane.
Isifinyezo se-organic compound. Igama elipheleleyo yi-4,4`-diaminostilbene-disulfonic acid. Ingasetyenziselwa ukuhlanganiswa kwe-agent emhlophe ye-fluorescent kunye nezinye iidayi. Inombolo yeCAS: 81-11-8 Ifomula yeMolekyuli:C14H14N2O6S2 Ubunzima beMolekyuli:370.4008 Isalathiso soMgangatho (Inkcazo) INkangeleko (Inkangeleko): umgubo otyheli okhanyayo / uMxholo wepaste etyheli okhanyayo (Ubunyulu): ≥95. 0 Ukupakisha (Iphakheji): 25 mg / kg.
I-0 Ukupakisha (Iipakethi): 25kg / 40kg / bag Properties Physical Ubunzima beMolekyuli: 370.4, ikristale ephuzi okanye ephuzi kunye ne-hygroscopicity. Kulula ukwenza i-oxidize emoyeni. Le mveliso inetyhefu kwaye iyacaphukisa ulusu, ugweme ukudibanisa ngqo nomzimba womntu.
Indlela ye-Synthesis: Indlela yangoku yokudibanisa yi-p-nitrotoluene sulfonated ne-fuming sulfuric acid, emva koko igalelwe ngamanzi, kwaye i-NTS eyahluliweyo ifakwe i-oxidized phantsi kweemeko zealkaline ngomoya, kwaye i-DNS kwisisombululo se-oxidation igalelwe ityuwa, emva koko iyancipha ngentsimbi. umgubo, kwaye emva koko ugalelwe nge-asidi ye-sulfuric. Umgubo womile kwaye womisiwe. Umgubo uthengiswa njengemveliso emanzi kwiintengiso zasekhaya, kodwa uthengiswa kuphela ngokohlobo lomgubo kurhwebo lwamazwe ngamazwe.
Inkampani yoshishino lweMit-ivy ikakhulu ivelisa iDSD ACID enesakhono sonyaka semveliso yeetoni eziyi-1,000,000, kwaye inesabelo esipheleleyo semarike esingama-97%.
