Nhanganyaya
Diethyl disulfide (inozivikanwawo sediethyl nitrogen disulfide) inhengo ye organosulfur. Inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye diethyldisulfide:
Hunhu:
-Kutaridzika: isina ruvara kune yakachenuruka yero mvura
- Solubility: Soluble mu organic solvents senge madoro, ethers, ethers uye ketoni, isinganyungudika mumvura.
Shandisa:
- Diethyldisulfide inowanzo shandiswa se crosslinker, vulcanizing agent uye difunctional modifier.
-Inopindirana nemapolymers ane amino uye hydroxyl mapoka kuti aumbe muchinjika-inobatanidza network kuvandudza simba uye kupfeka kuramba kwepolymer.
- Inogona zvakare kushandiswa seyakagadzirwa zvinhu zvecatalysts, achromatics, antioxidants, antimicrobial agents, nezvimwe.
Nzira:
- Diethyl disulfide inowanzo gadzirirwa ne ethanol reaction kuti ibudise thioether. Pasi pemamiriro ekuita, pamberi pe ethoxyethyl sodium catalysis, sulfur uye ethylene inoderedzwa ne lithium aluminate kuti iite ethylthiophenol, uye ipapo etherification reaction ne ethanol iri kuitika etherification reaction kuti iwane chigadzirwa chediethyldisulfide.
Zvekuchengetedza
- Diethyl disulfide imvura inopisa, kutarisirwa kunofanirwa kutorwa kudzivirira kupisa uye kupisa kwakanyanya.
- Chengetedza nzvimbo ine mhepo inofefetera zvakanaka panguva yekushandiswa nekuchengetedza.
- Pfeka midziyo yekudzivirira yakakodzera senge magurovhosi emakemikari, magirazi uye zvipfeko zvekudzivirira panguva yekushanda.
