Selelekela

Dibromomethane. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea dibromomethane:

 

Boleng:

E na le monko o hlabang mochesong oa kamore 'me ha e qhibilihe ka metsing, empa e qhibiliha ka har'a metsoako e mengata e tloaelehileng ea tlhaho.

Dibromomethyl ke ntho e tsitsitseng ea lik'hemik'hale e sa boleng kapa ea sebetsanang le liphetoho tsa lik'hemik'hale habonolo.

 

Sebelisa:

Dibromomethane e atisa ho sebelisoa e le solvent bakeng sa karabelo ea organic synthesis, ho qhibiliha kapa ho ntša lipids, li-resin le lintho tse ling tsa tlhaho.

Dibromomethane e boetse e sebelisoa e le lisebelisoa tse tala bakeng sa ho lokisoa ha metsoako e meng ea manyolo, 'me e na le likopo lits'ebetsong tse ling tsa indasteri.

 

Mokhoa:

Dibromomethane hangata e lokisoa ka ho arabela methane ka bromine.

Tlas'a maemo a karabelo, bromine e khona ho nkela athomo e le 'ngoe kapa ho feta tsa haedrojene sebakeng sa methane ho etsa dibromomethane.

 

Lintlha tsa Tšireletseho:

Dibromomethane e chefo 'me e ka monngoa ka ho hema, ho kopana le letlalo kapa ho e noa. Ho pepeseha ha nako e telele ho ka ba le litlamorao tse mpe tsa bophelo bo botle.

Lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana, likhalase le lithebe tsa sefahleho li lokela ho apesoa ha li sebelisoa.

Tlhokomelo e lokela ho nkoa ho qoba ho kopana le mehloli ea mollo ha u tšoara le ho boloka dibromomethane, kaha e ka chesa.

Dibromomethane e lokela ho bolokoa hole le mehloli ea mocheso le mocheso o phahameng sebakeng se phodileng, se nang le moea o motle.

Ha u sebelisa, u boloka kapa u tšoara dibromomethane, mekhoa e sireletsehileng ea ts'ebetso e lokela ho lateloa ka thata ho netefatsa polokeho ea botho. Boemong ba likotsi, mehato e loketseng ea tšohanyetso e lokela ho nkoa.
