Txog Sulphur Blue 7

CAS tus lej:1327-57-7

Cov Khoom: hmoov xiav-ntshav. Insoluble hauv dej, soluble hauv sodium sulfide kua yog ntsuab-grey. Nws yog xiav-ntshav hauv concentrated sulfuric acid thiab diluted rau hauv cov av xiav tsaus. Cov xim zas ua xim daj daj txiv ntseej hauv cov kua alkaline, thiab cov xim qub tuaj yeem rov qab tau tom qab oxidation; faded tag hauv sodium hypochlorite kua; Nws hloov xim xiav tsaus ntawm concentrated sulfuric acid.

Txoj kev tsim khoom: nitrosation ntawm phenol sodium nitrite thiab sulfuric acid los tsim p-nitrosyphenol, condensation nrog o-toluidine yaj hauv sulfuric acid, txo qis thiab vulcanization nrog sodium polysulfide nrog qee qhov sulfur reflection number, thiab tom qab ntawd los ntawm roj oxidation, thiab thaum kawg los ntawm kev lim, ziab, crushing thiab kev kho mob txheem los tsim cov khoom. Raw khoom noj (kg / t) O-toluidine (99%) 165-210 phenol (kev lag luam) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda tshauv (kev lag luam) 920-1120 sulfuric acid (100%) 900-1160 sulfur (99%) 430 sodium sulfide (63.5%) 480-620 Yuan hmoov 10

Siv: Nws yog qhov tsim nyog rau kev zas xim paj rwb, hemp, viscose thiab nws cov ntaub, thiab kuj tseem siv tau rau kev zas xim vinylon. Cov khoom no yog dyed navy xiav lub ntsiab xim zas xim, xim ci dua. Kev ruaj khov ntawm cov txheej txheem zas xim tsis zoo, yooj yim rau oxidize ib puas ntug liab, kab rov tav, liab qhov chaw thiab lwm yam tsis zoo, tshwj xeeb tshaj yog Sulphur xiav BRN, Sulphur xiav 7 yooj yim dua rau kev tswj hwm. Kev siv cov ntaub qhwv zas xim tuaj yeem txo qhov ntug liab, erythema thiab lwm yam tsis zoo. Vim tias tus lej ntawm cov pawg ntawm sodium polysulfide siv hauv kev tsim cov khoom no sib txawv, cov xim lag luam muaj xim sib txawv. Lub teeb xiav hu ua Sulphur xiav 7, lub teeb xiav liab hu uaXiav Sulphur 7, thiab lub teeb liab hu ua Sulphur xiav 7, uas yuav tsum tau them sai sai thaum siv. Sulphur xiav 7 tuaj yeem tsim los ntawm kev siv o-nitroethylbenzene, ib yam khoom siv hauv kev tsim cov chloramphenicol, es tsis txhob o-toluidine.

Peb lub tuam txhab feem ntau tsim tawmXim dub sulfur, Cov kua dub sulfur, Xiav Sulphur 7. Kev xa tawm mus rau Bangladesh, Is Nrias teb, Pakistan, Egypt, thiab Iran txhua xyoo. Ob qho tib si kev muab khoom thiab qhov zoo yog qhov ruaj khov tshwj xeeb. Qhov tseem ceeb tshaj plaws yog qhov zoo dua ntawm tus nqi.
