Ku saabsan Sulfur Blue 7

Lambarka CAS:1327-57-7

Guryaha: budada buluug-guduudan. Aan ku milmin biyaha, ku milmay milanka sodium sulfide waa cagaar-cawlan. Waa buluug-buluug oo ku jira sulfuric acid oo xoogaysan waxaana lagu qasi jiray roobab buluug madow ah. Midabku wuxuu noqdaa midab buluug ah oo huruud ah oo iftiin ah oo ku jira xalalka budada caymiska alkaline, iyo midabka asalka ah ayaa dib loo soo celin karaa ka dib oksaydhka; Si buuxda u baaba'ay xalka sodium hypochlorite; Waxay isu beddeshaa guduud mugdi ah sulfuric acid

Habka wax soo saarka: nitrosation of phenol sodium nitrite iyo sulfuric acid si loo soo saaro p-nitrosyphenol, uumi leh o-toluidine ku milmay sulfuric acid, hoos u dhigista iyo vulcanization leh sodium polysulfide oo leh nambarka milicsiga baaruud gaar ah, ka dibna iyada oo loo marayo oksidation gaaska, iyo ugu dambeyntii iyada oo loo marayo sifaynta. , qalajinta, burburinta iyo daaweynta caadiga ah si loo soo saaro alaabta. Isticmaalka alaabta ceeriin (kg/t) O-toluidine (99%) 165-210 phenol (warshad) 185-220 sodium nitrite 195-230 soodhaha caustic (100%) 1-20 soodhaha ash (warshad) 920-1120 sulfuric acid 100%) 900-1160 baaruud (99%) 430 sodium sulfide (63.5%) 480-620 Yuan budada 10

Isticmaala: Waxay ku habboon tahay midabaynta suufka, hemp, viscose iyo dharkeeda, waxaana sidoo kale loo isticmaali karaa midabaynta vinyl. Alaabtan waxaa lagu dheehday midab buluug ah oo buluug ah, midabkiisu aad buu u iftiimaa. Xasiloonida habka midabaynta waa mid liidata, fududahay in la oksijiso boqol gees oo casaan ah, siman, meel casaan ah iyo cillado kale, gaar ahaan Sulfur blue BRN, Sulfur blue 7 way fududahay in la barto. Isticmaalka midabaynta suufku waxay yarayn kartaa cidhifka cas, erythema iyo cilladaha kale. Sababtoo ah tirada dufcadaha polysulfide sodium ee loo isticmaalo wax soo saarka alaabtan way kala duwan yihiin, midabada ganacsiga ayaa leh midabyo kala duwan. Nalka buluuga ah waxaa lagu magacaabaa Sulfur blue 7, nalka buluuga ah ee casaanka ah ayaa loo yaqaanSulfur buluug 7, iyo iftiinka cas waxaa loo yaqaan Sulfur blue 7, kaas oo ah in fiiro gaar ah loo yeesho marka la isticmaalo. Sulfur blue 7 waxaa lagu soo saari karaa iyadoo la isticmaalayo o-nitroethylbenzene, oo ah wax soo saarka chloramphenicol, halkii o-toluidine.
