Na Waiwai Kemika::

ʻO Toluene, he mea hoʻohuihui mea ola me ke ʻano kemika C₇H₈, he wai waihoʻoluʻu ʻole me ka ʻala ʻala. He waiwai refractive ikaika kona. Hiki ke hui pū me ka ethanol, ether, acetone, chloroform, carbon disulfide a me glacial acetic acid, a hiki ke hoʻoheheʻe iki ʻia i ka wai. Hiki ke ahi, hiki i ka mahu ke hana i kahi hui pahū me ka ea, hiki ke pahū ka leo o ka hui ʻana ma kahi haʻahaʻa. ʻona haʻahaʻa, LD50 (iole, waha) 5000mg/kg. kiʻekiʻe o ke kinoea he narcotic, irritating

Noi:

Loaʻa ka Toluene mai ka lanahu a me ka aspetroleum. Loaʻa ia i loko o ka ʻaila a me ka nui o nā solvents petroleum. Hoʻohana ʻia ka Toluene e hana i trinitrotoluene (TNT), toluene diisocyanate, a me benzene; ma ke ʻano he mea hana fordyes, lāʻau lapaʻau, a me nā mea holoi; a ma ke ʻano he mea hoʻoheheʻe ʻoihana no nā ʻōpala, pena, nā ʻili, a me nā aila.

He nui nā noi o Toluene i ka ʻoihana kemika a me ka ʻaila, me 6 miliona mau tona i hoʻohana ʻia i kēlā me kēia makahiki ma ʻAmelika Hui Pū ʻIa a me 16 miliona mau tona i hoʻohana ʻia ma ka honua holoʻokoʻa. ʻO ka hoʻohana nui ʻana o toluene ma ke ʻano he octane booster i ka ʻaila. He helu octane ka Toluene he 114. ʻO Toluene kekahi o nā pūhui ʻala nui ʻehā, me benzene, xylene, a me ethylbenzene, i hana ʻia i ka wā hoʻomaʻemaʻe e hoʻomaikaʻi i ka hana o ka ʻaila. ʻO ka hui pū ʻana, ua hoʻopau ʻia kēia mau pūhui ʻehā ʻo BTEX. ʻO BTEX kahi mea nui o ka ʻaila, hoʻokumu ʻia ma kahi o 18% ma ke kaumaha o kahi hui maʻamau. ʻOiai ʻokoʻa ka hapa o nā mea ʻala e hana i nā hui like ʻole e hoʻokō i nā koi ʻāina a me nā kau, ʻo toluene kekahi o nā mea nui. Aia ma kahi o 5% toluene ma ke kaumaha o ka ʻaila maʻamau.
ʻO Toluene kahi meaʻai mua i hoʻohana ʻia no ka hana ʻana i nā pūhui organik like ʻole. Hoʻohana ʻia ia e hana i nā diisocyanates. Aia i loko o ka Isocyanates ka pū'ulu hana ?N = C = O, a 'o ka diisocyanates 'elua o ia mau mea. ʻO nā diisocyanates nui ʻelua he toluene 2,4-diisocyanate a me ka toluene 2,6-diisocyanate. ʻO ka hana ʻana o nā diisocyanates ma ʻAmelika ʻĀkau kokoke i kahi piliona paona i kēlā me kēia makahiki. ʻOi aku ma mua o 90% o ka hana toluene diisocyanate i hoʻohana ʻia no ka hana ʻana i nā ʻōpū polyurethanes. Hoʻohana ʻia nā mea hope e like me ka hoʻopiha piha ʻana i nā lako, nā moena, a me nā cushions.Ma ke ʻano ʻoʻoleʻa ua hoʻohana ʻia ia no ka insulation, nā uhi paʻa paʻa, nā mea kūkulu hale, nā ʻāpana kaʻa, nā huila androller skate.

I ka hana ʻana i ka waikawa benzoic, benzaldehyde, nā mea pahū, nā mea hoʻonaninani, a me nā mea hoʻohui ʻē aʻe he nui; ma ke ʻano he mea hoʻoheheʻe no nā pena, lacquers, gums, resins; ʻoi aku ka lahilahi no ka ʻīnika, nā mea ʻala, nā mea pena; i ka unuhi ʻana i nā loina like ʻole mai nā mea kanu; e like me ka mea hoʻohui ʻaila.
