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

Intshayelelo

I-3,3'-Dithiobis (2,5-dimethyl) furan, eyaziwa ngokuba yi-DMTD, i-organosulfur compound. Oku kulandelayo sintshayelelo kwezinye iipropati zayo, ukusetyenziswa, iindlela zokuvelisa, kunye nolwazi lokhuseleko:

Umgangatho:

- Imbonakalo: I-DMTD lulwelo olungenambala ukuya kolutyheli olukhanyayo kunye nevumba elikhethekileyo le-thioether.

- Ukunyibilika: I-DMTD ayinyibiliki emanzini kwaye inyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, kunye neehydrocarbons.

Sebenzisa:

- I-DMTD isetyenziswa njenge-vulcanization accelerator kunye ne-preservative. Ingasetyenziswa kwishishini lerabha ukukhuthaza ukusabela kwe-vulcanization yerabha kunye nokuphucula amandla, ukuxhathisa ukunxiba kunye nokumelana nokuguga kweemveliso zerabha.

Indlela:

- I-DMTD inokulungiswa ngokusabela kwe-dimethyl disulfide (DMDS) kunye ne-dimethylfuran. Ukusabela kwenzeka kumaqondo obushushu aphezulu (150-160 °C) kwaye iphantsi kwedistillation kunye namanye amanyathelo okulungisa ukufumana imveliso ecocekileyo.

Ulwazi ngoKhuseleko:

- I-DMTD inevumba elinukayo kwaye kufuneka ithintelwe ukuba sesichengeni ixesha elide.

- Kwiindawo zemveliso yemizi-mveliso, umoya ofanelekileyo kunye namanyathelo okukhusela umntu afana neeglavu, iiglasi kunye nempahla yokukhusela kufuneka ibe khona.

-I-DMTD iyacaphukisa ulusu kunye namehlo, ngoko kunqande ukudibana nayo.

-Xa ugcina kwaye usebenzisa, zigcine kude namaqondo obushushu aphezulu, amadangatye avulekileyo, kunye nee-oxidizing agents.
