Intshayelelo

I-Dimethyl sulfide (ekwabizwa ngokuba yi-dimethyl sulfide) yi-inorganic sulfur compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dimethyl sulfide:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala kunye nevumba elikhethekileyo elinamandla.

-Ukunyibilika: ukuxutywa ne-ethanol, ii-ethers, kunye nezinyibilikisi ezininzi zezinto eziphilayo.

 

Sebenzisa:

- Izicelo zoshishino: I-Dimethyl sulfide isetyenziswa ngokubanzi njenge-solvent kwi-organic synthesis reactions, ngokukodwa kwi-sulfidation kunye ne-thioaddition reactions.

 

Indlela:

- I-Dimethyl sulfide inokulungiswa ngokuphendula ngokuthe ngqo kwe-ethanol kunye nesulfure. Ukusabela ngokuqhelekileyo kwenzeka phantsi kweemeko ze-acidic kwaye kufuna ukufudumeza.

- Isenokulungiswa ngokugalela i-sodium sulfide kwii-methyl bromides ezimbini (umz. i-methyl bromide).

 

Ulwazi ngoKhuseleko:

- I-Dimethyl sulfide inevumba elibi kwaye inefuthe elicaphukisayo esikhumbeni namehlo.

- Kuphephe ukudibana nolusu kunye namehlo kwaye uthathe izilumkiso ezifanelekileyo xa usebenzisa.

- Ngexesha lokusetyenziswa kunye nokugcinwa, ukudibanisa kunye ne-oxidants kunye ne-acids eqinile kufuneka kugwenywe ukuphepha ukuphendula okungakhuselekanga.

- Inkunkuma kufuneka ilahlwe ngokuhambelana nemithetho yengingqi kunye nemimiselo kwaye akufanele ilahlwe.

- Gcina umoya ococekileyo ngexesha lokugcinwa kunye nokusetyenziswa.
