Intshayelelo

Umgangatho:

- Methylbenzene lulwelo olungenambala kunye nevumba elimnandi elingaqhelekanga.

- I-Trimethylbenzene ayinyibiliki emanzini kwaye i-soluble kwii-solvents eziphilayo ezifana ne-alcohol, i-ethers kunye ne-ketone solvents.

Sebenzisa:

- I-M-trimethylbenzene isetyenziswa kakhulu njenge-solvent kwi-organic synthesis.

- Isetyenziswa ekulungiseleleni incasa, ii-pigments, iidayi kunye ne-fluorescents.

- Ukulungiselela i-inki, abacoci kunye neengubo.

Indlela:

- I-Methylbenzene inokulungiswa kwi-toluene nge-alkylation. Indlela eqhelekileyo kukusabela kwi-toluene kunye ne-methane phantsi kweemeko ze-catalyst kunye nobushushu obufanelekileyo ukwenza i-homoxylene.

Ulwazi ngoKhuseleko:

- I-Trimethylbenzene inetyhefu ethile kunye nemiphumo ecaphukisayo eluswini kunye namehlo.

- I-Trimethylbenzene inokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu. Nika ingqalelo kumanyathelo okuthintela umlilo xa ugcina kwaye usebenzisa.

- Xa usebenzisa i-x-trimethylbenzene, bonelela ngeemeko ezilungileyo zokungenisa umoya kwaye ugweme ukuphefumla umphunga wayo.

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

Okulandelayo: I-4-Hydroxybenzyl alcohol(CAS#623-05-2)
