Intshayelelo
I-Dimethiomethane (ekwabizwa ngokuba yi-methyl sulfide) yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dimethylthiomethane:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala
- Ivumba: Inevumba elinamandla lehydrogen sulfide
-Ukunyibilika: Inyibilika kwizinyibilikisi ezininzi eziphilayo ezifana ne-ethanol kunye ne-ether
Sebenzisa:
- Njenge-solvent: I-Dimethiomethane yinto ebalulekileyo ye-solvent engasetyenziselwa ukunyibilika nokucoca i-organic compounds.
- I-Chemical synthesis: Ihlala isetyenziswa njenge-reagent kwaye iphakathi kwi-organic synthesis, kwaye ithatha inxaxheba kwi-alkylation ethile, i-oxidation, i-sulfidation kunye nezinye iimpendulo.
- Izinto zePolymer: I-Dimethylthiomethane ingasetyenziselwa ukudibanisa kunye nokuguqulwa kweepolymers.
Indlela:
- I-Dimethylthiomethane inokufumaneka ngokuphendula i-methyl mercaptan kunye ne-dimethyl mercaptan. Ekuphenduleni, iodide yesodium okanye i-sodium bromide idla ngokusetyenziswa njenge-catalyst.
Ulwazi ngoKhuseleko:
- I-Dimethylthiomethane inevumba elibi kwaye iyacaphukisa amehlo, ulusu kunye nomgudu wokuphefumla. Iiglavu ezikhuselayo, iiglasi zokhuseleko kunye nokhuseleko lokuphefumla kufuneka zinxitywe xa zisetyenziswa.
- Ngexesha lokugcinwa kunye nokuphatha, ukudibanisa kunye nee-oxidizing agents eziqinileyo kunye ne-acids kufuneka kugwenywe ukukhusela ukuphendula kweekhemikhali eziyingozi.
- Xa itshisiwe, i-dimethylthiomethane ivelisa iigesi ezinetyhefu (umz. i-sulphur dioxide) kwaye kufuneka isetyenziswe kwindawo engena umoya.
- Xa uphethe kwaye ulahla inkunkuma, nceda ulandele imigaqo efanelekileyo yendawo kunye nemimiselo.
