Nā hoʻohana o ka phenol

Phenolhe ʻano hui pūhui me ka hoʻolālā apo benzene. He wai ʻawaʻawa a me ka ʻala hoʻonāukiuki. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka etera, a hiki ke hoʻoheheʻe ʻia i loko o benzene, toluene a me nā mea hoʻoheheʻe kūlohelohe ʻē aʻe. He mea koʻikoʻi ka Phenol i ka ʻoihana kemika a hiki ke hoʻohana ʻia no ka synthesis o nā pūhui ʻē aʻe, e like me nā plasticizers, dyes, herbicides, lubricants, surfactants a me nā mea hoʻopili. No laila, hoʻohana nui ʻia ka phenol i ka hana ʻana o kēia mau ʻoihana. Eia kekahi, he mea koʻikoʻi ka phenol i ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i nā lāʻau lapaʻau he nui, e like me ka aspirin, penicillin, streptomycin a me tetracycline. No laila, nui loa ka noi no ka phenol ma ka mākeke.

 

ʻO ke kumu nui o ka phenol ka lanahu tar, hiki ke unuhi ʻia e ke kaʻina distillation tar. Eia kekahi, hiki ke hana ʻia ka phenol e nā ala ʻē aʻe he nui, e like me ka decomposition o benzene a me toluene i mua o nā catalysts, ka hydrogenation o nitrobenzene, ka hoʻemi ʻana o ka phenolsulfonic acid, a me nā mea ʻē aʻe. loaʻa ma ka decomposition o cellulose a i ʻole ke kō ma lalo o ke kūlana kiʻekiʻe o ka wela a me ke kaomi.

 

Ma waho aʻe o nā ʻano o luna, hiki ke loaʻa ka phenol ma o ka ʻohi ʻana i nā huahana kūlohelohe e like me ka lau kī a me nā pī koko. Pono e ʻōlelo ʻia ʻo ke kaʻina hana ʻoki ʻana o nā lau kī a me nā pī koko ʻaʻohe haumia i ke kaiapuni a he ala nui hoʻi ia e loaʻa ai ka phenol. I ka manawa like, hiki i nā pīni koko ke hana i kekahi mea waiwai nui no ka synthesis o nā plasticizers - phthalic acid. No laila, ʻo ka pī koko kekahi mea waiwai nui no ka hana ʻana i nā plasticizers.

 

Ma keʻano laulā, hoʻohana nui ʻia ka phenol i nā ʻoihana like ʻole a loaʻa kahi manaʻo mākeke maikaʻi loa. No ka loaʻa ʻana o nā huahana phenol kiʻekiʻe, pono mākou e hoʻolohe i ke koho ʻana i nā mea maka a me nā kūlana kaʻina hana i ke kaʻina hana e hōʻoia i ka hoʻokō ʻana o nā huahana i nā kūlana kūpono a me nā koi.
