Numera CAS:1327-57-7
Meatotino: paʻu lanumoana-lanu viole.E le mafai ona solu i le vai, solu i le sodium sulfide solution e lanumeamata-efuefu.E lanumoana-lanu violē i le sulfuric acid fa'ato'atoa ma fa'afefeteina i se pa'epa'e lanumoana uliuli.O le vali e avea ma lanu samasama malamalama lanu olive i le alkaline inisiua pa'u vaifofo, ma le lanu muamua e mafai ona toe fa'afo'i pe a uma oxidation;Ua mou atoa ile vaifofo ole sodium hypochlorite;E liu lanu viole pogisa ile sulfuric acid
Gaosiga auala: nitrosation o le phenol sodium nitrite ma sulfuric acid e maua ai p-nitrosyphenol, condensation ma o-toluidine solo i sulfuric acid, faaitiitia ma vulcanization ma sodium polysulfide ma se numera o le sulfur atagia, ona e ala i le kesi oxidation, ma mulimuli ane e ala i filtration , faʻamago, tuʻimomomoina ma faʻataʻitaʻiina togafitiga e gaosia ai oloa.Fa'aaogāina o mea mata (kg/t) O-toluidine (99%) 165-210 phenol ( alamanuia) 185-220 sodium nitrite 195-230 sua (100%) 1-20 soda efuefu ( alamanuia) 920-1120 sulfuric acid ( 100%) 900-1160 sulfur (99%) 430 sodium sulfide (63.5%) 480-620 Yuan pauta 10
Fa'aoga: E talafeagai mo le valiina o le cotton, hemp, viscose ma ona ie, ma e mafai foi ona fa'aoga mo le valiina o le vinylon.O lenei oloa e valiina le lanu moana lanumoana lanu autu, o le lanu e sili atu ona susulu.E le lelei le mautu o le valiina, faigofie ona faʻamaʻiina le selau lanu mumu, faʻalava, lanu mumu ma isi faaletonu, aemaise lava Sulfur blue BRN, Sulfur blue 7 e faigofie ona faʻatautaia.O le fa'aogaina o le vali vali e mafai ona fa'aitiitia ai le pito mumu, erythema ma isi fa'aletonu.Ona o le numera o vaega o le sodium polysulfide o loʻo faʻaaogaina i le gaosiga o lenei oloa e ese, o lanu faʻatau pisinisi e eseese lanu.O le moli lanumoana e taʻua o le Sulfur blue 7, o le lanu mumu lanumoana e taʻuaSulfur Blue 7, ma o le moli mumu e taʻua o Sulfur blue 7, lea e tatau ona gauai atu i ai pe a faʻaaogaina.O le sulfur blue 7 e mafai ona gaosia e ala i le fa'aaogaina o le o-nitroethylbenzene, o se mea e maua mai i le gaosiga o le chloramphenicol, nai lo le o-toluidine.
O la matou kamupani e tele lava ina gaosiaSulfur uliuli, Sulfur Black Suavai, Sulfur Blue 7.Fa'aola fa'atauva'a i Bangladesh.Initia.Pakistan.Aikupito, ma Iran.O le sapalai ma le tulaga lelei e sili ona mautu.E sili atu le taua o le tau faʻamanuiaga
