Isingeniso
I-Diethyl disulfide (eyaziwa nangokuthi i-diethyl nitrogen disulfide) iyinhlanganisela ye-organosulfur. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-diethyldisulfide:
Ikhwalithi:
- Ukubukeka: Uketshezi olungenambala kuya kokuphuzi okuphaphathekile
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, ama-ether nama-ketone, okungancibiliki emanzini.
Sebenzisa:
- I-Diethyldisulfide ivamise ukusetshenziswa njenge-crosslinker, i-vulcanizing agent kanye ne-difunctional modifier.
- Ihlangana nama-polymers aqukethe amaqembu e-amino kanye ne-hydroxyl ukwakha inethiwekhi exhumanisayo ukuze kuthuthukiswe amandla nokumelana nokugqoka kwe-polymer.
- Ingasetshenziswa futhi njengento eluhlaza yama-catalysts, achromatics, ama-antioxidants, ama-antimicrobial agents, njll.
Indlela:
- I-Diethyl disulfide ivamise ukulungiselelwa ukusabela kwe-ethanol ukukhiqiza i-thioether. Ngaphansi kwezimo zokusabela, lapho kukhona i-ethoxyethyl sodium catalysis, isulfure ne-ethylene zincishiswa nge-lithium aluminate ukuze kwakhiwe i-ethylthiophenol, bese kuthi ukusabela kwe-etherification nge-ethanol kubhekane nokusabela kwe-etherification ukuze kutholwe umkhiqizo we-diethyldisulfide.
Ulwazi Lokuphepha:
- I-Diethyl disulfide iwuketshezi oluvuthayo, kufanele kuqashelwe ukugwema ukuthungela kanye namazinga okushisa aphezulu.
- Gcina indawo enomoya omuhle ngesikhathi sokusebenzisa nokugcina.
- Gqoka izinto zokuzivikela ezifanele njengamagilavu amakhemikhali, izibuko, nezingubo zokuzivikela ngesikhathi sokusebenza.
