Glacial Acetic Acid maleng mandha - piny ma tiyo ku yore madwong man jamb tiyo maber pi yubu piny ma kwo
Ber pa piny
1.Ultra-High Purity & Stability:
≥99.5% maleng timo tic maber, ma kelo adwogi maber, maber pi timo piny ma pire tek (e.g., piny ma jutiyo kudu pi yath, piny ma jutiyo kudu pi pii).
2.Bedo maber:
Lab-Grade: Ber pi timo lembe ma nok man ponji mi tic.
Industrial-Grade: Ecopu tiyo ku lembe ma jutimo i rwom ma malu man ma rwinyo, ikinde utiye microwave reactors man high-pressure systems.
3.Gwok man bedo ma rii:
Jam piny ma jugwoko maber (ma juyike ma pii copo mol ngo + pong pa yamo ma nyai) juku pii kud i pii man nyayu piny ma rac, nimakere ku cik mi ISO 14001 mi gwoko kwo pa piny.
Jucopo tiyo kudu kendu nikadhu kud i distillation nyo adsorption, ma dwoko piny ma rac ku 70%.
4.Bedo maber:
Eloko asidi ma nyai (calu, asidi sulfuric) calu acid ma tek, ma jwigo nyai pa jam tic.
Tiyu karacelu ku pii ma ionic pi medo rwom pa tic man dwoko piny kare mi dwoko piny.
Tic ma rwinyo
Yath:
Esterification pa ibuprofen (yield up to 98%).
Amidation pa cefalexin (selectivity umedire ku 20%).
Kemikol mabecu:
Yubu midu: Yubu maber pa esters (e.g., isoamyl acetate, benzyl acetate).
Dye intermediates: Catalytic oxidation of benzoic acid derivatives (reaction temperature reduced by 15%).
Ngec mi Polymer:
Polyester resin synthesis: Eco-friendly PET production via transesterification.
Cellulose acetate: Jutiyo kudu i bongo mi yath man i jam piny ma copo nyothre.
Analytical Chemistry:
Polar solvent pi HPLC mobile phase preparation.
Sample pretreatment: Dwoko piny ma rwinyo ngo maber (e.g., alkaloids, steroids).
