Hordhac

Tayada:

Methylbenzene waa dareere aan midab lahayn oo leh ur udgoon oo gaar ah.

- Trimethylbenzene waa mid aan lagu milmin biyaha waxayna ku milmayaan dareerayaasha organic sida khamriga, ethers iyo ketone dareerayaasha.

Isticmaal:

- M-trimethylbenzene waxaa inta badan loo isticmaalaa sida dareere ah in synthesis organic.

Waxaa loo isticmaalaa diyaarinta dhadhanka, midabada, midabada iyo fluorescents.

- Diyaarinta khadadka, nadiifiyeyaasha iyo dahaarka.

Habka:

- Methylbenzene waxaa laga diyaarin karaa toluene by alkylation. Habka caadiga ah waa in lagu falceliyo toluene leh methane iyada oo la raacayo shuruudaha kicinta iyo heerkulka ku habboon si loo sameeyo homoxylene.

Macluumaadka Badbaadada:

- Trimethylbenzene waxay leedahay qaar sun ah iyo saameyn cuncun maqaarka iyo indhaha.

- Trimethylbenzene waa guban karta waana in laga fogeeyaa ololka furan iyo heerkulka sare. U fiirso tillaabooyinka ka hortagga dabka marka aad kaydinayso oo aad isticmaalayso.

- Markaad isticmaalayso x-trimethylbenzene, bixi xaalado hawo wanaagsan oo iska ilaali neefsashada uumiga.

Kii hore: 2,4,6-Trimethylnitrobenzene anion radical (CAS#34505-32-3)

Xiga: 4-Hydroxybenzyl khamriga (CAS#623-05-2)
