Intshayelelo
2,3-Butanedithiol. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2,3-butanedithiol:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala
- Ivumba: Ivumba elibi
-Inyibilika: Inyibilika emanzini, kwiialkoholi nakwizinyibilikisi ze-ether
Sebenzisa:
- Ukusetyenziswa kwamashishini: I-2,3-butanedicaptan ingasetyenziswa njenge-accelerator ye-rubber kunye ne-antioxidant. Inokuphucula iimpawu zemishini kunye nokumelana nokushisa kwerubha kunye nokwandisa ubomi benkonzo yeemveliso zerabha.
Indlela:
Ukulungiswa kwe-2,3-butanedithiol kunokwenziwa ngenye yezi ndlela zilandelayo:
- Ukulungiswa kwemizi-mveliso: ibutene kunye nesalfure zisetyenziswa ngokuqhelekileyo njengemathiriyeli ekrwada kwaye zilungiswe yi-vulcanization reaction.
- Ukulungiswa kweLebhu: Inokulungiswa ngokusabela kwepropadiene sulfate kunye ne-sodium sulfite, okanye ngokuphendula kwe-2,3-dichlorobutane kunye ne-sodium sulfide.
Ulwazi ngoKhuseleko:
- I-2,3-butanedithiol iyacaphukisa kwaye inokubangela ukucaphuka kunye nokutshisa kwamehlo kunye nolusu.
- Ukuphefumla inani elikhulu le-2,3-butanedithiol kunokubangela isiyezi, isicaphucaphu, ukuhlanza kunye nezinye iimpawu ezingathandekiyo.
- Kuphephe ukuphefumla kunye nokunxibelelana kwesikhumba ngexesha lokusebenza, kwaye unxibe izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, izibuko, njl.njl. xa usebenzisa.
- Kulumkele ukudibana neeoksidi kunye nezinto ezinjengeeasidi ezomeleleyo kunye neealkali ukunqanda ukusabela okuyingozi.
