I ka ʻoihana kemika, isopropanol (Isopropanol)he mea hoʻoheheʻe koʻikoʻi a me ka hana ʻana i nā mea maka, hoʻohana nui ʻia ma nā ʻano āpau. Ma muli o kona flammability a me nā pilikia olakino, ʻo ka maʻemaʻe a me nā kikoʻī noiʻi nā kumu nui e noʻonoʻo ai i ke koho ʻana i nā mea hoʻolako isopropanol. E hāʻawi kēia ʻatikala i kahi alakaʻi hoʻolako piha no nā poʻe loea i ka ʻoihana kemika mai ʻekolu mau ʻano: nā kūlana maʻemaʻe, nā koi noi, a me nā manaʻo koho.
Nā waiwai a me ka hoʻohana ʻana o Isopropanol
ʻO ka Isopropanol kahi kemika kala ʻole a ʻala ʻole me ke ʻano kemika C3H8O. He wai hikiwawe loa ia (Note: Ua haʻi ka kikokikona kumu i ka "gas", ʻaʻole pololei; ʻo ka isopropanol he wai ma ka lumi wela) me kahi paila o 82.4°C (Note: ʻAʻole pololei ka "202°C" o ka kikokikona kumu; ʻo ka paila kūpono o ka isopropanol ma kahi o 82.4°C/0³ kumu. ʻAʻole pololei ka ʻōlelo "0128g/cm³" ma kahi o 0.786 g/cm³). He nui ka hoʻohana ʻana o Isopropanol i ka ʻoihana kemika, ka mea nui me ka hana ʻana i ka acetone a me ka ethyl acetate, e lawelawe ana ma ke ʻano he solvent a me ka solubilizer, a me nā noi i nā biopharmaceuticals, cosmetics, a me ka hana uila.
Mea nui a me nā kūlana o ka maʻemaʻe
Ka wehewehe a me ke koʻikoʻi o ka maʻemaʻe
Hoʻoholo pololei ka maʻemaʻe o isopropanol i kona pono a me ka palekana i nā noi like ʻole. He kūpono ka isopropanol maʻemaʻe kiʻekiʻe no nā manawa e koi ana i ka pololei kiʻekiʻe a me ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa, e like me ka biopharmaceuticals a me ka hana kemika kiʻekiʻe. ʻO ka isopropanol hoʻomaʻemaʻe haʻahaʻa, ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻopilikia i ka maikaʻi o ka huahana a hiki i nā pōʻino palekana.
Nā ʻano no ka nānā ʻana i ka maʻemaʻe
Hoʻoholo ʻia ka maʻemaʻe o ka isopropanol e nā ʻano loiloi kemika, me ka chromatography kinoea (GC), kiʻekiʻe-performance liquid chromatography (HPLC), a me nā ʻenehana thin-layer chromatography (TLC). ʻOkoʻa nā kūlana ʻike no ka isopropanol maʻemaʻe kiʻekiʻe e like me kā lākou hoʻohana. No ka laʻana, ʻo ka isopropanol i hoʻohana ʻia i nā biopharmaceuticals pono e hōʻea i ka maʻemaʻe o 99.99%, ʻoiai ʻo ka mea i hoʻohana ʻia i ka hana ʻoihana pono e hiki i ka 99% maʻemaʻe.
Ka hopena o ka maʻemaʻe ma luna o nā noi
He mea koʻikoʻi ka isopropanol maʻemaʻe kiʻekiʻe i nā noi biopharmaceutical no ka mea pono ka maʻemaʻe kiʻekiʻe loa e hōʻoia i ka paʻa a me ka pono o nā lāʻau lapaʻau. I nā noi ʻoihana, ʻoi aku ka haʻahaʻa o ka pono maʻemaʻe, akā pono ia e kaʻawale i nā mea haumia ʻino.
Nā Koina Noi o Isopropanol
Nā lāʻau lapaʻau biopharmaceutical
I loko o nā biopharmaceuticals, hoʻohana pinepine ʻia ka isopropanol e hoʻopau i nā lāʻau lapaʻau, kōkua iā lākou e hoʻoheheʻe a hoʻopuehu paha ma lalo o nā kūlana kikoʻī. Ma muli o kona hoʻoheheʻe maikaʻi ʻana a me ka hemo wikiwiki ʻana, pono loa ka isopropanol i nā haʻawina pharmacokinetic. Pono ka maʻemaʻe ma mua o 99.99% e pale ai i nā haumia mai ka hoʻopili ʻana i ka hana a me ke kūpaʻa o nā lāʻau lapaʻau.
Hana Hana Kemika
I ka hana ʻenehana ʻenehana, hoʻohana pinepine ʻia ka isopropanol ma ke ʻano he solvent a me ka solubilizer, e komo ana i nā hopena kemika. Ma kēia kahua noi, ʻoi aku ka haʻahaʻa o ka pono maʻemaʻe, akā pono ia e kaʻawale i nā haumia ʻino e pale aku i nā pōʻino palekana.
Hana Uila
I ka hana uila, hoʻohana pinepine ʻia ka isopropanol ma ke ʻano he solvent a me ka mea hoʻomaʻemaʻe. Ma muli o kona volatility kiʻekiʻe, ua loaʻa i ka ʻoihana hana uila nā koi maʻemaʻe kiʻekiʻe loa no ka isopropanol e pale ai i nā haumia mai ka hoʻohaumia ʻana i nā mea uila. ʻO Isopropanol me ka maʻemaʻe o 99.999% ka koho kūpono.
Kahua Hoomalu Kaiapuni
Ma ke kahua palekana kaiapuni, hoʻohana pinepine ʻia ka isopropanol ma ke ʻano he solvent a me ka mea hoʻomaʻemaʻe, me ka degradability maikaʻi. Pono kona hoʻohana ʻana e hoʻokō i nā lula mālama kaiapuni e pale aku i ka hoʻohaumia ʻana i ke kaiapuni. No laila, pono ka isopropanol no ka mālama ʻana i ke kaiapuni i ka palapala hōʻoia kūlohelohe e hōʻoia i ka maʻemaʻe a me ka hana palekana.
Nā ʻokoʻa ma waena o ka Isopropanol maʻemaʻe a me ka Isopropanol i hui ʻia
Ma nā noi kūpono, ʻo ka isopropanol maʻemaʻe a me ka isopropanol hui ʻia ʻelua mau ʻano maʻamau o isopropanol. ʻO ka isopropanol maʻemaʻe e pili ana i ke ʻano o 100% isopropanol, aʻo ka isopropanol i hui ʻia he hui ʻia o isopropanol a me nā mea hoʻoheheʻe ʻē aʻe. Hoʻohana pinepine ʻia ka isopropanol i hui ʻia i nā noi ʻoihana kūikawā, e like me ka hoʻomaikaʻi ʻana i kekahi mau waiwai o nā solvents a i ʻole e hoʻokō i nā koi kaʻina hana. ʻO ke koho ma waena o nā ʻano isopropanol ʻelua e pili ana i nā pono noi kūikawā a me nā koi maʻemaʻe.
Nā Manaʻo Manaʻo a me nā Manaʻo
Ke koho ʻana i kahi kūpono mea hoʻolako isopropanolʻO ka maʻemaʻe a me nā koi noi nā kumu nui. ʻO nā mea hoʻolako isopropanol wale nō e hāʻawi i ka maʻemaʻe kiʻekiʻe a hoʻokō i nā kūlana noi kikoʻī he mau hoa hilinaʻi. Manaʻo ʻia e heluhelu pono ka poʻe loea i ka ʻoihana kemika i nā palapala hōʻoia maʻemaʻe o ka mea hoʻolako a wehewehe i kā lākou pono noi ma mua o ka hoʻoholo ʻana i ke kūʻai.
He mea koʻikoʻi ka maʻemaʻe a me ka noi noi o isopropanol i ka ʻoihana kemika. Ma ke koho ʻana i nā mea hoʻolako isopropanol e hāʻawi ana i nā huahana maʻemaʻe kiʻekiʻe e hālāwai ana i nā kūlana noi, hiki ke hōʻoia i ka palekana o ke kaʻina hana a me ka maikaʻi o ka huahana.
