Intshayelelo
I-Diethyl disulfide (ekwabizwa ngokuba yi-diethyl nitrogen disulfide) yi-organosulfur compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-diethyldisulfide:
Umgangatho:
- Imbonakalo: Ayinabala ukuya kulwelo olumthubi
- Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, ii-ethers kunye neeketones, ezinganyibilikiyo emanzini.
Sebenzisa:
- I-Diethyldisulfide isetyenziswa ngokuqhelekileyo njenge-crosslinker, i-agent ye-vulcanizing kunye ne-difunctional modifier.
- Isabela kunye neepolymers eziqulethe amaqela e-amino kunye ne-hydroxyl ukwenza inethiwekhi yokudibanisa i-cross-link ukuze kuphuculwe amandla kunye nokumelana nokunxiba kwepolymer.
- Inokusetyenziswa kwakhona njengento ekrwada ye-catalysts, i-achromatics, i-antioxidants, i-antimicrobial agents, njl.
Indlela:
I-Diethyl disulfide idla ngokulungiswa yi-ethanol reaction ukuvelisa i-thioether. Phantsi kweemeko zokusabela, phambi kwe-ethoxyethyl sodium catalysis, isulfure kunye ne-ethylene ziyancitshiswa yi-lithium aluminate ukuze zenze i-ethylthiophenol, kwaye emva koko i-etherification reaction kunye ne-ethanol iphantsi kwe-etherification reaction ukuze ifumane imveliso ye-diethyldisulfide.
Ulwazi ngoKhuseleko:
- I-Diethyl disulfide iyilwelo oluvuthayo, kufuneka kuthathelwe ingqalelo ukuphepha ukutshisa kunye nokushisa okuphezulu.
- Gcina indawo enomoya kakuhle ngexesha lokusetyenziswa kunye nokugcinwa.
- Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zekhemikhali, iiglasi, kunye nempahla yokukhusela ngexesha lokusebenza.
