Phenothiazine: Mea Hoʻohui Nui me nā noi like ʻole

ʻO ka Phenothiazine, he mea hoʻohuihui mea ola nui me ke ʻano molekala C12H9NS, ua ʻohi i ka manaʻo no kāna mau noi ākea ma waena o nā ʻoihana like ʻole. Mai nā lāʻau lapaʻau i nā huahana mahiʻai, ʻo kāna mau waiwai kūʻokoʻa e pono ai i nā kaʻina hana.

Ua ʻike mua ʻia ma ke ʻano he melemele a ʻōmaʻomaʻo-hina ʻeleʻele a i ʻole ka mea crystalline, ʻo ka solubility o phenothiazine i loko o benzene, ether, a me ka wai acetic wela, me kona insolubility i ka wai a me ka petroleum ether, ua hoʻopiʻi i ka hoihoi o nā mea noiʻi. ʻO kona hiki ke keʻakeʻa i nā monomer vinyl i paʻa i ke ala no kona hoʻohana nui ʻana i ka hana ʻana i ka waikawa acrylic, nā esters acrylic, methyl methacrylate, a me ka vinyl acetate. ʻAʻole i hoʻoponopono wale kēia noi i nā kaʻina hana hana akā ua hoʻonui pū i ka maikaʻi o ka huahana.

Ma waho aʻe o kāna hana i ka hana polymer, he hana koʻikoʻi ka phenothiazine i ka synthesis pharmaceutical. ʻO kona komo ʻana i ka hana ʻana i nā antihistamines, tranquilizers, a me nā lāʻau lapaʻau ʻē aʻe e hōʻike ana i kona koʻikoʻi i ka ʻoihana olakino. Hoʻohui, loaʻa ka phenothiazine i ka pono i ka synthesis o nā dyes, antioxidants, a me polyethers, e hōʻike hou ana i kāna versatility i ka ʻoihana kemika.

Ma ka mahiʻai, lawelawe ʻo phenothiazine ma ke ʻano he mea nui i nā dewormers holoholona a me nā insecticides no nā lāʻau hua. ʻO kona kūpono e kūʻē i nā ʻano parasite a me nā inike e hōʻike ana i kona koʻikoʻi i ka mālama ʻana i ke olakino holoholona a me ka pale ʻana i nā mea kanu. Eia nō naʻe, ʻo kona ʻona a me ka hopena o ke kaiapuni e pono ai ka hoʻohana pono a me ka mālama ʻana i nā lula palekana.

ʻOiai ʻo kāna mea hoʻohana kupaianaha, ʻaʻohe pilikia o ka phenothiazine. ʻO ka mālama lōʻihi e alakaʻi i ka pōʻeleʻele o ka kala a me ka maʻalahi i ka oxidation, e hoʻoikaika ana i ka pono o ka mālama pono ʻana a me ka mālama ʻana. Eia kekahi, ʻo kāna mau waiwai sublimation a me ka hoʻonāukiuki ʻana i ka ʻili e hōʻike ana i ke koʻikoʻi o ka mālama palekana i kāna hana ʻana a me ka hana ʻana.

I ka hopena, ʻo nā waiwai multifaceted o phenothiazine e lilo ia i waiwai waiwai ma waena o nā ʻoihana. Mai ka hoʻonui ʻana i ka pono o ka lāʻau i ka pale ʻana i nā hua mahiʻai, ʻaʻole hiki ke hōʻole ʻia kāna mau haʻawina. Ke hoʻomau nei ka noiʻi i ka wehe ʻana i nā noi hou a hoʻomaʻemaʻe i nā kaʻina hana e kū nei, ua paʻa ke kuleana o ka phenothiazine i ka hoʻomohala ʻana i nā ʻāpana like ʻole o ka hoʻokele waiwai.
