Glacial Acetic Acid Uas Muaj Peev Xwm Siab - Ib qho Catalyst thiab Green Solvent rau Organic Synthesis
Cov txiaj ntsig tseem ceeb
1. Kev Ntshiab Siab Tshaj Plaws & Kev Ruaj Ntseg:
≥99.5% kev huv si ua kom muaj kev ua haujlwm zoo, muaj txiaj ntsig zoo, zoo tagnrho rau cov tshuaj syntheses rhiab heev (piv txwv li, cov tshuaj nruab nrab, cov khoom siv siv lead ua kua).
2. Kev siv tau ntau yam:
Qib Kuaj: Haum rau kev ua kom zoo dua qub ntawm cov tshuaj tiv thaiv me me thiab kev tshawb fawb txog cov txheej txheem.
Qib Kev Lag Luam: Sib xws nrog cov txheej txheem tsim khoom loj thiab cov txheej txheem tsim khoom tas mus li, suav nrog cov tshuab hluav taws xob microwave thiab cov tshuab siab.
3. Kev Nyab Xeeb & Kev Ruaj Ntseg:
Cov ntim khoom kaw (tsim kom tsis txhob xau + sau cov roj inert) tiv thaiv kev ua pa thiab kev ua qias tuaj, ua raws li ISO 14001 cov qauv ib puag ncig.
Siv tau dua los ntawm kev distillation lossis adsorption, txo cov khib nyiab ntau dua 70%.
4. Kev Siv Nyiaj Zoo:
Hloov cov kua qaub corrosive (piv txwv li, sulfuric acid) ua cov tshuaj catalyst acid muaj zog, txo qhov xeb ntawm cov khoom siv.
Ua ke nrog cov kua ionic los txhim kho cov txiaj ntsig thiab luv lub sijhawm ua haujlwm.
Cov Ntawv Thov Ib Txwm Muaj
Cov Tshuaj:
Esterification ntawm ibuprofen (cov txiaj ntsig txog li 98%).
Kev sib xyaw ntawm cefalexin (kev xaiv ntau ntxiv 20%).
Cov Tshuaj Zoo:
Kev tsim cov tsw qab: Kev tsim cov esters ntuj ntsuab (piv txwv li, isoamyl acetate, benzyl acetate).
Cov xim nruab nrab: Catalytic oxidation ntawm benzoic acid derivatives (qhov kub ntawm cov tshuaj tiv thaiv txo los ntawm 15%).
Kev Tshawb Fawb Txog Polymer:
Kev tsim cov tshuaj polyester resin: Kev tsim cov PET uas zoo rau ib puag ncig los ntawm kev hloov pauv.
Cellulose acetate: Siv rau hauv cov ntaub qhwv kho mob thiab cov ntim khoom uas lwj tau.
Kev Tshuaj Xyuas Tshuaj:
Cov kuab tshuaj polar rau HPLC mobile theem npaj.
Qauv kev kho ua ntej: Kev yaj cov tshuaj uas yaj tsis tau zoo (piv txwv li, alkaloids, steroids).
