Selelekela

Dimethiomethane (eo hape e tsejoang e le methyl sulfide) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea dimethylthiomethane:

 

Boleng:

- Ponahalo: Mokelikeli o se nang 'mala

- Monko: E na le monko o matla oa hydrogen sulfide

- Sollubility: E qhibiliha ka har'a lihlapolli tse ngata tsa tlhaho tse kang ethanol le ether

 

Sebelisa:

- Joaloka solvent: Dimethiomethane ke motsoako oa bohlokoa oa tlhaho o ka sebelisoang ho qhaqha le ho hloekisa metsoako ea tlhaho.

- Motsoako oa lik'hemik'hale: Hangata e sebelisoa e le reagent le lipakeng tsa organic synthesis, 'me e nka karolo ho alkylation, oxidation, sulfidation le liketso tse ling.

- Lisebelisoa tsa polymer: Dimethylthiomethane e ka boela ea sebelisoa bakeng sa ho kopanya le ho fetola li-polymers.

 

Mokhoa:

- Dimethylthiomethane e ka fumanoa ka ho arabela methyl mercaptan ka dimethyl mercaptan. Ka karabelo, sodium iodide kapa sodium bromide hangata e sebelisoa e le sesosa.

 

Lintlha tsa Tšireletseho:

- Dimethylthiomethane e na le monko o hlabang hape e tena mahlo, letlalo le tsela ea ho hema. Liatlana tse sireletsang, likhalase tsa tšireletso le tšireletso ea phefumoloho li lokela ho apesoa ha li sebelisoa.

- Nakong ea ho boloka le ho tšoara, ho kopana le li-oxidizing tse matla le li-acids li lokela ho qojoa ho thibela lik'hemik'hale tse kotsi tsa lik'hemik'hale.

- Ha e chesoa, dimethylthiomethane e hlahisa likhase tse chefo (mohlala, sulfur dioxide) 'me e lokela ho sebelisoa sebakeng se nang le moea o motle.

- Ha o sebetsana le ho lahla litšila, ka kopo latela melao le melaoana e amehang ea lehae.
