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%.
