Selelekela

Boleng:

- Methylbenzene ke mokelikeli o se nang 'mala o nang le monko o monate o ikhethang.

- Trimethylbenzene ha e qhibilihe ka metsing 'me e qhibiliha ka har'a metsoako ea tlhaho e kang alcohols, ethers le ketone solvents.

 

Sebelisa:

- M-trimethylbenzene e sebelisoa haholo-holo e le mokelikeli ka har'a organic synthesis.

- E sebelisoa ha ho etsoa litlolo, li-pigments, dae le li-fluorescent.

- Bakeng sa ho lokisa li-inks, lihloekisi le liphahlo.

 

Mokhoa:

- Methylbenzene e ka lokisoa ho tloha toluene ka alkylation. Mokhoa o tloaelehileng ke ho itšoara ka toluene ka methane tlas'a maemo a catalyst le mocheso o loketseng ho etsa homoxylene.

 

Lintlha tsa Tšireletseho:

- Trimethylbenzene e na le chefo e itseng le litlamorao tse khopisang letlalong le mahlo.

- Trimethylbenzene e ka cha 'me e lokela ho bolokoa hole le malakabe a bulehileng le mocheso o phahameng. Ela hloko mehato ea thibelo ea mollo ha u boloka le ho sebelisa.

- Ha o sebelisa x-trimethylbenzene, fana ka maemo a matle a moea le ho qoba ho hema mouoane oa eona.
