Isopropyl cawv thiab isopropanol yog tib yam tshuaj lom neeg uas tsis muaj qhov sib txawv ntawm cov muaj pes tsawg leeg; lawv yog ob lub npe rau 2-propanol (CAS 67-63-0) siv sib hloov hauv kev lag luam.
Chemistry
Hais txog cov qauv tshuaj thiab purity, ob qho tib si xa mus rau tib lub molecule C₃H₈O. Cov khoom lag luam feem ntau raug faib ua 70%, 99%, lossis anhydrous isopropanol (Ntau dua lossis sib npaug rau 99.9%). Qib anhydrous muaj cov ntsiab lus dej hauv qab 0.1%, uas yog qhov tseem ceeb rau kev siv hluav taws xob thiab kev ua kom huv si.
| Khoom | Tus nqi |
|---|---|
| Tshuaj Formula | C3H8O |
| Molecular Luj | 60.1 g / mol |
| Boiling Point | ~ 82.5 degree |
| Solubility | Miscible nrog dej |
Kev Siv Hluav Taws Xob
Los ntawm kev xav txog kev lag luam, ob nqe lus hais txog tib cov kuab tshuaj siv hauv txheej txheej, tshuaj, thiab khoom siv hluav taws xob. Txawm li cas los xij, cov kev xav tau sib txawv: piv txwv li, kev tu semiconductor feem ntau xav tau ntau dua lossis sib npaug rau 99.9% anhydrous IPA, thaum degreasing thiab ntxuav saum npoo yuav siv 70-99% cov kev daws teeb meem, nyob ntawm seb tus nqi evaporation thiab kev nyab xeeb.
Toxicity thiab kev nyab xeeb
Hais txog kev nyab xeeb thiab tuav,isopropanolmuaj qhov taw tes nyem ntawm kwv yees li 11.7 degree, ua rau nws muaj cov nplaim taws kub hnyiab tau nyob rau hauv ib puag ncig puag ncig (GHS Qeb 2). Yog li ntawd, ob qho tib si "isopropyl cawv" thiab "isopropanol" ua raws tib yam kev nyab xeeb kev faib tawm, lub ntsiab lus khaws cia, thauj, thiab kev tuav pov hwm yog tib yam txawm hais tias lub npe sib cog lus.
Tianjin Gnee Biotech Co., Ltd.yog ib lub chaw tsim khoom thiab exporter ntawm isopropanol thiab lwm yam tshuaj raw cov ntaub ntawv, muab cov khoom zoo ruaj khov, nruj zoo tswj, thiab txhim khu kev qha khoom rau cov neeg muas zaub thoob ntiaj teb.
