Hoʻolauna

ʻAno maikaʻi:

- He wai waihoʻoluʻu ʻole ka Methylbenzene me kahi ʻala ʻala.

- ʻAʻole hiki ke hoʻoheheʻe ʻia ʻo Trimethylbenzene i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā alcohols, ethers a me ketone solvents.

 

E hoʻohana:

- Hoʻohana nui ʻia ka M-trimethylbenzene ma ke ʻano he solvent i ka synthesis organik.

- Hoʻohana ʻia i ka hoʻomākaukau ʻana i nā mea ʻono, nā puaʻa, nā mea pena a me nā fluorescents.

- No ka hoʻomākaukau ʻana i nā inika, nā mea hoʻomaʻemaʻe a me nā uhi.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka Methylbenzene mai toluene e ka alkylation. ʻO ke ʻano maʻamau, ʻo ia ka hoʻopili ʻana i ka toluene me ka methane ma lalo o nā kūlana o kahi catalyst a me ka mahana kūpono e hana ai i ka homoxylene.

 

ʻIke palekana:

- Loaʻa i ka Trimethylbenzene kekahi mau mea make a me nā hopena hoʻonāukiuki i ka ʻili a me nā maka.

- He mea wela ka Trimethylbenzene a pono e mālama ʻia mai ke ahi ākea a me nā wela kiʻekiʻe. E noʻonoʻo i nā hana pale ahi ke mālama a hoʻohana.

- I ka hoʻohana ʻana i ka x-trimethylbenzene, hāʻawi i nā kūlana hoʻoluʻu maikaʻi a pale i ka inhalation o kāna mau mahu.
