Intangiriro

Ubwiza:

- Methylbenzene ni amazi atagira ibara afite impumuro idasanzwe.

- Trimethylbenzene ntishobora gushonga mumazi kandi igashonga mumashanyarazi nka alcool, ethers hamwe na ketone.

Koresha:

- M-trimethylbenzene ikoreshwa cyane nkigisubizo muri synthesis.

- Ikoreshwa mugutegura flavours, pigment, amarangi na fluorescents.

- Mugutegura wino, isuku hamwe na coatings.

Uburyo:

- Methylbenzene irashobora gutegurwa kuva toluene na alkylation. Uburyo busanzwe ni ugukora toluene hamwe na metani mubihe bya catalizator hamwe nubushyuhe bukwiye kugirango habeho homoxylene.

Amakuru yumutekano:

- Trimethylbenzene ifite uburozi ningaruka zitera uruhu n'amaso.

- Trimethylbenzene irashya kandi igomba kubikwa kure yumuriro nubushyuhe bwinshi. Witondere ingamba zo gukumira umuriro mugihe ubitse kandi ukoresha.

- Mugihe ukoresheje x-trimethylbenzene, tanga uburyo bwiza bwo guhumeka kandi wirinde guhumeka umwuka wacyo.

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

Ibikurikira: 4-Inzoga ya Hydroxybenzyl (CAS # 623-05-2)
