Selelekela

Dimethyl sulfide (eo hape e tsejoang e le dimethyl sulfide) ke motsoako oa sebabole oa inorganic. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea dimethyl sulfide:

 

Boleng:

- Ponahalo: Mokelikeli o se nang mebala o nang le monko o khethehileng o matla.

- Sollubility: e kopane le ethanol, ethers le litlhare tse ngata tsa organic.

 

Sebelisa:

- Lits'ebetso tsa indasteri: Dimethyl sulfide e sebelisoa haholo joalo ka mokelikeli ho karabelo ea organic synthesis, haholo karabelo ea sulfidation le thioaddition.

 

Mokhoa:

- Dimethyl sulfide e ka lokisoa ka karabelo e tobileng ea ethanol le sebabole. Karabelo hangata e etsahala tlasa maemo a asiti mme e hloka ho futhumatsa.

- E ka boela ea lokisoa ka ho eketsa sodium sulfide ho tse peli tsa methyl bromide (mohlala, methyl bromide).

 

Lintlha tsa Tšireletseho:

- Dimethyl sulfide e na le monko o hlabang 'me e na le phello e khopisang letlalong le mahlo.

- Qoba ho ama letlalo le mahlo 'me u nke mehato e nepahetseng ha u sebelisa.

- Nakong ea ts'ebeliso le polokelo, ho kopana le li-oxidants le li-acid tse matla ho lokela ho qojoa ho qoba ts'ebetso e sa sireletsehang.

- Litšila li lokela ho lahloa ho latela melao le melaoana ea lehae 'me ha lia lokela ho lahleloa.

- Boloka moea o nepahetseng nakong ea polokelo le tšebeliso.
