DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) waa dhex dhexaad dheeha muhiim ah, inta badan loo isticmaalo in lagu soo saaro dhalaalaysa fluorescent, jaalaha ah si toos ah barafaysan, R jaalle toos ah, oranji F3G u adkaysta iftiinka qoraxda iyo wakiilada ka hortagga aboor-cunista. COD-ku waa 6000-8000mg/L, milixdu waa 6%-8%, midabkuna waa 50,000 jeer; Qaybaha ugu muhiimsan ee biyaha wasakhda ah waa xeryahooda organic caraf udgoon leh nitro, amino iyo kooxaha sulfonic, iyo saamiga BOD iyo COD waa kaliya 0.03, taas oo aad u adag in biodegrade.

Tayada biyaha iyo tirada biyaha ee wax soo saarka aashitada DSD biyaha wasakhda ah waa kuwo deggan, laakiin chromaticity iyo sulfate-ka ayaa aad u sarreeya, nafaqooyinka sida N iyo P ayaa maqan, biyaha wasakhda ah waxaa ku jira walxo sun ah iyo walxo waxyeello leh, ma jirto daaweyn lagu guuleystay tusaale Shiinaha. dsd acid waa koollo huruud ah oo khafiif ah ama budo, oo ku milma ethanol iyo ether, aan lagu milmin biyaha, ku milma alkali. (2) Si sahal ah ayay oksaydhisku ugu gelaysaa casaan, waxayna leedahay sifooyinka udgoonka iyo aminyada isku mar.

3) Tayada badeecada iyo tilmaanta farsamada: wadarta qiimaha amino (sida ku cad cadadka koollada) ≥48%; badeecada qalalan wadarta qiimaha amino (sida ku cad wadarta guud ee shaybaarada qalajinta) ≥95.0%; Walxaha aan milmayn ee alkali (marka la eego wadarta cadadka koollada) ≤0.05%; Maaddada aan milmi karin ee alkali (marka loo eego wadarta guud ee budada) ≤0.08%; Maaddada benzyl (wadarta tirada muunadyada) ≤0.25% ee soo saarista walxaha caddeeya, wakiilka fluorescent, walaxda caddaynta, wax caddeeya, wax caddeeya, wax caddeeya, fluorescent, wax caddeeya, wax cadeenaya, fluorescent ah, wax caddeeya, fluorescent, wax cadeenaya, fluorescent. J jaalle ah baraf toos ah iyo jaalle toos ah, oo loo isticmaalo sidii cayayaanka.

Soo gaabinta isku dhafka dabiiciga ah. Magaca buuxa waa 4,4`-diaminostilbene-disulfonic acid. Waxaa loo isticmaali karaa isku-dhafka wakiilka caddeynta fluorescent iyo midabyo kale. CAS lambar 0 Xidhmada (Xirmooyinka): 25 mg/kg.

0 Xirmooyinka (Xirmooyinka): 25kg/40kg/bac Astaanta Jireed Miisaanka Unugyada: 370.4, Huruud ama huruud khafiif ah oo leh hygroscopicity. Way fududahay in hawada lagu oksijiso. Alaabtani waa sun iyo cuncun maqaarka, iska ilaali taabashada tooska ah ee jidhka bini'aadamka.

Habka synthesis: Habka hadda loo isticmaalo waa p-nitrotoluene sulfonated leh qiiqa sulfuric acid, ka dibna biyo lagu shubay, iyo NTS kala soocay waa oksaydhized hoos xaaladaha alkaline hawada, iyo DNS ee xal oksaydhisku waxaa lagu da'ay milix, ka dibna la dhimay birta. budada, ka dibna lagu shubo sulfuric acid. Budada waa la qalajiyey oo la qalajiyey. Budada waxaa loo iibiyaa sida alaab qoyan oo iibka gudaha ah, laakiin waxa kaliya oo lagu iibiyaa qaab budo ah ganacsiga caalamiga ah.

Shirkadda warshadaha Mit-ivy waxay inta badan soo saartaa DSD ACID oo leh awood wax-soo-saar sanadle ah 1,000,000 tan, waxayna leedahay saami suuq ah oo dhan 97%.
