Kev txheeb xyuas txoj kev ntawm isopropanol

Isopropanol yog ib qho organic compound, ib qho isomer ntawm n-propanol, tseem hu ua dimethyl methanol thiab 2-propanol. Nws tseem hu ua IPA hauv isopropanol manufacturers. Nws yog cov kua uas tsis muaj xim pob tshab, zoo ib yam li cov ntxhiab tsw ntawm ethanol thiab acetone. Soluble nyob rau hauv dej, tab sis kuj soluble nyob rau hauv cawv, ether, benzene, chloroform thiab lwm yam organic solvents. Isopropanol yog ib qho tseem ceeb ntawm cov khoom siv tshuaj thiab cov khoom siv raw. Isopropanol tuam ntxhab feem ntau siv nws hauv cov tshuaj, tshuaj pleev ib ce, yas, txuj lom, txheej, thiab lwm yam.

Cov yam ntxwv: cov kua tsis muaj xim thiab pob tshab, nrog cov ntxhiab tsw ntawm ethanol thiab acetone sib tov, tuaj yeem ua rau miscible nrog cawv, ether, chloroform thiab dej, tuaj yeem yaj alkaloids, roj hmab, shellac, rosin, hluavtaws cob thiab lwm yam organic thiab qee yam inorganic tshuaj, daim ntawv. azeotrope nrog dej, thiab yog insoluble nyob rau hauv ntsev tov. Nws tuaj yeem ignite thiab hlawv nyob rau hauv chav tsev kub, thiab nws cov chav yog ib qho yooj yim los tsim explosive sib tov thaum tov nrog huab cua.

Isopropanol yog nquag tsim peroxide, uas qee zaum yuav tsum tau txheeb xyuas ua ntej siv. Txoj kev sim yog: noj {{0}}.5ml isopropanol, ntxiv 1ml10 feem pua ​​​​poov tshuaj iodide tov thiab 0.5ml1:5 dilute hydrochloric acid thiab ob peb tee ntawm starch tov, co rau 1 feeb, yog hais tias nws tig xiav. los yog xiav dub, nws qhia tias muaj peroxide. Nws zoo ib yam li ethanol thiab propanol, tab sis nws muaj cov yam ntxwv ntawm cov cawv thib ob.
