Intshayelelo

I-2-Methyl-2-propanethiol yi-organosulfur compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-methyl-2-propane mercaptan:

 

Umgangatho:

- Lulwelo olungenambala nevumba elirhabaxa.

-Inyibilika kwizinyibilikisi ezininzi eziphilayo ezifana neealkoholi, ii-ethers kunye neehydrocarbons.

 

Sebenzisa:

- I-2-Methyl-2-propanethiol ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis.

 

Indlela:

I-2-Methyl-2-propanethiol inokulungiswa ngu:

- I-Isopropanol iphendulwa ngesulfure ukufumana i-2-methyl-2-propyl-1,3-dithiocyanol, kwaye ke i-2-methyl-2-propanethiol ifunyenwe ngokunciphisa ukusabela.

- Inokufumaneka ngokusabela kwe-isopropyl magnesium bromide kunye ne-hydrogen sulfide.

 

Ulwazi ngoKhuseleko:

- I-2-Methyl-2-propanethiol yinto ephazamisayo enokuthi ibangele iliso, ulusu, kunye nokuphazamiseka kokuphefumula xa udibene.

- Iinkqubo zokusebenza ezikhuselekileyo kufuneka zilandelwe ngokungqongqo xa kusetyenziswa naxa kugcinwa, kwaye kusetyenzwe kwindawo engena umoya.
