Tshuaj Solvent Ethyl acetate (CAS 141-78-6)yog dav siv nyob rau hauv ntau yam lag luam, tab sis txawv daim ntawv thov yuav tsum tau sib txawv purity theem thiab ua raws li cov qauv.
Kev nkag siab txog qhov sib txawv ntawm kev lag luam, tshuaj, thiab zaub mov-qib (E1504) ethyl acetate yog qhov tseem ceeb rau cov tuam txhab lag luam hauv kev lag luam sib txawv los xyuas kom meej cov khoom ua tau zoo, kev nyab xeeb, thiab ua raws.
Kab lus no yuav qhia txog peb qib tseem ceeb: qib kev lag luam (rau kev tsim khoom niaj hnub), qib tshuaj (rau kev kho mob precision), thiab qib zaub mov (hu ua E1504, rau cov neeg siv khoom ruaj ntseg) los pab koj txiav txim siab yuav khoom.
Dab tsi txiav txim siab Ethyl Acetate hnyav zoo?
- Purity: Siab purity kom ruaj khov khoom ua haujlwm; tsawg impurity cov ntsiab lus.
- Cov ntsiab lus noo noo: Cov dej noo ntau dhau tuaj yeem ua rau cov khoom tsis ruaj khov.
- Acidity (cov ntsiab lus acetic acid).
- Impurities: Cov kuab tshuaj uas tsis tshua muaj (piv txwv li, ethanol) zam kev tawm ntawm - ntxhiab tsw thiab txaus ntshai.
- Xim (APHA): Yuav tsum yog qhov tseeb thiab pob tshab, yuav luag tsis muaj xim.
