Kev yaj tau: Nws tuaj yeem sib xyaw nrog dej, ethanol, ether, acetone, thiab lwm yam organic solvents.
Lwm Cov Khoom: Nws qhov hnyav molar yog 60.10 g / mol, qhov ceev yog 0.786 g / mL (ntawm 25 ℃), qhov taw tes yaj yog - 89.5 ℃, thiab qhov taw tes kub yog 82.3 ℃. Lub ntsiab lus flash yog 11.7 ℃.
Cov Cheeb Tsam Thov
Cov kuab tshuaj: Nws ua haujlwm ua cov kuab tshuaj zoo heev rau shellac, nitrocellulose, alkaloids, roj hmab, roj, thiab lwm yam. Nws kuj siv rau hauv kev tsim cov tshuaj tua kab thiab cov tshuaj ntxuav iav. Tsis tas li ntawd, nws tuaj yeem ua haujlwm ua cov extractant rau cov roj noob paj rwb thiab cov txuj lom.
Cov Khoom Siv Raw hauv Kev Lag Luam Tshuaj Organic: Los ntawm ntau yam kev tshuaj tiv thaiv, nws tuaj yeem tsim ntau yam khoom siv tshuaj xws li isopropylamine, methyl isobutyl ketone, methyl isobutyl carbinol, thiab lwm yam. Cov khoom no tau siv dav hauv kev lag luam xws li tshuaj, tshuaj tua kab, tshuaj pleev xim, thiab kua mem.
Kev Ua Tshuaj: Nws yog ib yam khoom siv raw rau kev tsim cov tshuaj xws li Propranolol, Rifampicin, Pindolol, Diisopropylamine Dichloroacetate, thiab lwm yam. Nws tuaj yeem siv los rho cov vitamins thiab ntxuav cov tshuaj ntsiav tshuaj. Nws feem ntau yog siv los ua tshuaj tua kab mob rau daim tawv nqaij, cov khoom siv prostheses, thiab cov khoom siv kho mob, thiab kuj tuaj yeem siv rau kev khaws cia cov qauv tshuaj lom neeg.
Kev Lag Luam Hluav Taws Xob: Cawv isopropyl uas muaj purity siab yog siv los ua tus neeg ntxuav thiab etchant thaum lub sijhawm tsim cov khoom semiconductor thiab kev sib dhos thiab kev ua cov integrated circuits loj heev. Nws kuj tseem siv tau ua tus neeg ntxuav hlau.
Kev Ua Haujlwm Tsheb: Ua ib yam khoom siv roj, nws tuaj yeem ua rau cov roj av muaj octane ntau dua, ua rau cov roj av zoo dua. Nws kuj tseem siv tau ua cov tshuaj ntxuav iav tsheb, tshuaj ntxuav iav qhov rais, thiab tshuaj tiv thaiv pos huab rau iav qhov rais aerosol.
Cov Txheej Txheem Npaj
Kev ua kom dej ntawm propylene: Tam sim no, txoj kev tseem ceeb yog kev ua kom propylene noo ncaj qha. Hauv qab qhov kev ua ntawm cov tshuaj catalyst, propylene ncaj qha cuam tshuam nrog dej los ntawm kev ntxiv cov tshuaj tiv thaiv kom tsim tau isopropyl cawv. Raws li theem ntawm cov tshuaj reactants, nws tuaj yeem faib ua txoj kev theem roj, roj - kua sib xyaw ua ke, thiab txoj kev theem kua.
Kev txiav txim siab ntawm acetone hauv cov ntshav: Nyob rau hauv qhov kev ua ntawm ib qho catalyst, acetone raug txo kom ua isopropyl cawv hauv huab cua hydrogen. Txoj kev no muaj qhov kub thiab txias qis dua, qhov siab ib txwm muaj, kev siv hluav taws xob tsawg, kev ua haujlwm yooj yim, thiab kev xeb tsawg dua rau cov khoom siv.
Kev ua kom huv ntawm Isopropyl Acetate: Nyob rau hauv qhov kev ua ntawm ib qho catalyst, isopropyl acetate yog hydrogenated kom tib lub sijhawm tsim isopropyl cawv thiab ethanol. Txawm li cas los xij, muaj ntau yam by-products, thiab kev sib cais ntawm ethanol thiab isopropyl cawv yog qhov nyuaj, yog li nws tsis tau siv dav.
Cov kev ceev faj
Cov pa ntawm isopropyl cawv ua rau lub qhov muag thiab daim tawv nqaij khaus, thiab kev ua pa tuaj yeem lom. Nws yog ib feem ntawm Pawg 3 carcinogen. Thaum tib neeg nqus cov pa sib txawv ntawm isopropyl cawv, lawv yuav muaj cov tshuaj tiv thaiv sib txawv. Piv txwv li, ntawm 400 ppm, nws yuav ua rau khaus me ntsis rau lub qhov muag, qhov ntswg, thiab caj pas, thiab ntawm 20000 ppm, nws yuav ua rau lub neej lossis kev noj qab haus huv muaj kev phom sij tam sim ntawd.
Cawv Isopropyl yog cov khoom siv uas yooj yim hlawv. Nws cov pa ua pa tuaj yeem ua rau muaj kev sib xyaw nrog huab cua. Nws tuaj yeem ua rau muaj kev kub hnyiab thiab tawg thaum raug rau cov nplaim taws qhib thiab kub heev. Nws yuav tsum khaws cia rau hauv qhov chaw txias thiab muaj cua nkag, deb ntawm cov chaw hluav taws thiab cov chaw kub, tiv thaiv kom tsis txhob raug tshav ntuj ncaj qha, thiab lub thawv yuav tsum kaw. Nws yuav tsum khaws cia cais ntawm cov tshuaj oxidants.
