I-Bis(2-5-Dimethyl-3-furyl) disulfide (CAS#28588-73-0)

Isingeniso

I-3,3′-Dithiobis(2,5-dimethyl)furan, eyaziwa nangokuthi i-DMTD, iyinhlanganisela ye-organosulfur. Okulandelayo yisingeniso kwezinye zezakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza, kanye nolwazi lokuphepha:

Ikhwalithi:

- Ukubukeka: I-DMTD iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elikhethekile le-thioether.

- Ukunyibilika: I-DMTD ayincibiliki emanzini futhi incibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, nama-hydrocarbon.

Sebenzisa:

- I-DMTD isetshenziswa njenge-accelerator ne-preservative. Ingasetshenziswa embonini yenjoloba ukukhuthaza ukusabela kwe-vulcanization yerabha futhi kuthuthukise amandla, ukumelana nokugqoka kanye nokumelana nokuguga kwemikhiqizo yenjoloba.

Indlela:

- I-DMTD ingalungiswa ngokusabela kwe-dimethyl disulfide (DMDS) nge-dimethylfuran. Ukusabela kwenzeka emazingeni okushisa aphezulu (150-160 °C) futhi kugaywa ziphuzo zazihluzwa nezinye izinyathelo zokucubungula ukuze kutholwe umkhiqizo omsulwa.

Ulwazi Lokuphepha:

- I-DMTD inephunga elimnandi futhi kufanele igwenywe ngokuchayeka isikhathi eside.

- Ezindaweni zokukhiqiza ezimbonini, ukungena komoya ngendlela efanele kanye nezinyathelo zokuzivikela ezifana namagilavu, izibuko, nezingubo zokuzivikela kufanele kube khona.

- I-DMTD iyacasula isikhumba namehlo, ngakho gwema ukuthintana nayo.

- Lapho ugcina futhi usebenzisa, gwema amazinga okushisa aphezulu, amalangabi avulekile, nama-oxidizing agents.
