Isingeniso

I-Dimethyl sulfide (eyaziwa nangokuthi i-dimethyl sulfide) iyinhlanganisela yesulfure engaphili. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimethyl sulfide:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala olunephunga elikhethekile elinamandla.

- Ukunyibilika: kuxubene ne-ethanol, ama-ether, nezinyibilikisi eziningi eziphilayo.

 

Sebenzisa:

- Izicelo zezimboni: I-Dimethyl sulfide isetshenziswa kabanzi njenge-solvent ekuphenduleni kwe-organic synthesis, ikakhulukazi ekuphenduleni kwe-sulfidation kanye ne-thioaddition.

 

Indlela:

- I-Dimethyl sulfide ingalungiswa ngokusabela okuqondile kwe-ethanol nesibabule. Ukusabela ngokuvamile kwenzeka ngaphansi kwezimo ezine-acidic futhi kudinga ukushiswa.

- Ingalungiswa futhi ngokungeza i-sodium sulfide kuma-methyl bromide amabili (isb. i-methyl bromide).

 

Ulwazi Lokuphepha:

- I-Dimethyl sulfide inephunga elimnandi futhi inomphumela ocasulayo esikhumbeni nasemehlweni.

- Gwema ukuthinta isikhumba namehlo futhi uthathe izinyathelo ezifanele lapho usebenzisa.

- Ngesikhathi sokusetshenziswa nokugcinwa, ukuthintana nama-oxidants nama-asidi aqinile kufanele kugwenywe ukuze kugwenywe ukusabela okungaphephile.

- Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo kanye neziqondiso futhi akufanele ilahlwe.

- Gcina umoya ohlanzekile ngesikhathi sokugcina nokusetshenziswa.
